AP United States History

1. Before the Mayflower: a crowded continent

Learning goal: Describe Native American adaptation to Europeans without treating Native societies as bystanders.

In 1491 the Americas held many societies with different farming, trade and political systems. Period 1 of the course (1491 to 1607) asks you to treat them as active. They traded, fought, allied, resisted and borrowed. The 2025 Set 1 Long Essay Question 2 asked how Native American societies adapted to European colonists in North America between 1500 and 1754, spanning Periods 1 and 2, so a good essay needs a verb for what Native people did, not only what happened to them.

Europeans brought horses, metal tools, livestock and disease, and took back crops such as maize and potatoes. Historians call this two-way movement the Columbian Exchange. Spanish colonizers built labor and tribute systems such as the encomienda. Where Spanish power was thin, Pueblo, Plains and other societies could use horses or trade goods to change their own politics.

Adaptation can mean military alliance, new trade routes, religious blending, migration or resistance. It is not the same as defeat. Before you write a claim, name the society, name the change, and name the reason the group chose it.

Practice turning a topic into a claim with verbs. Weak: "Native Americans and Europeans traded." Stronger: "Native groups used trade with Europeans to gain metal tools and goods, and some used those goods to strengthen their own power over neighbors." The second sentence says what Native people did and why it mattered. Try the same with alliance, migration and resistance, and keep the group in the subject of the sentence.

Watch for a common trap: treating the Columbian Exchange as one-way. Horses, livestock and disease came from Europe, while crops such as maize and potatoes moved the other way, and both changed societies on both sides of the Atlantic. Disease changed population and politics, and survivors had to rebuild. An invented but plausible outline for an essay: claim, one example of trade or alliance, one example of migration or religious blending, and a closing sentence on change over time. Always mention the period you are in, so your evidence matches the dates.

Worked example

Write a claim about Native adaptation that includes a group, a change and a reason.

1. Choose a society that actually used a European introduction.
2. State the change in what that society did.
3. Add why the group might have chosen it.
4. Combine them: some Plains societies adopted horses, allowing them to travel across the Great Plains to hunt bison.

Mental model: Adaptation needs a group, a change and a reason.

Common trap: Treating Native Americans as one undifferentiated group.

2. Colonies with different moods

Learning goal: Separate political developments from economic and social ones in colonial British North America.

The SAQ on colonial politics in 2025 asked for one political development in British North America from 1607 to 1753. The Chief Reader noted that responses often struggled to distinguish types of developments. HYPOTHETICAL exercise (invented for practice): if an answer only describes exports, it gives an economic development; explain a change in government or political authority when the prompt asks for politics.

Political developments are about who held power and how decisions were made. Virginia's House of Burgesses began meeting in 1619. The Mayflower Compact of 1620 was an agreement among settlers to govern themselves. New England towns used town meetings. Economic developments, by contrast, concern labor, production and trade, such as cash crops or the Atlantic trade.

Conflicts over land, including Metacom's War in 1675 to 1676, were political and military as colonists and Native groups fought over authority and territory. A strong answer labels the type of development in its own words, then supports it with a specific example.

Sort developments with a simple three-column habit. Political: who holds power and how decisions are made, such as the House of Burgesses, the Mayflower Compact or town meetings. Economic: how people made a living or traded, such as tobacco, rice or the Atlantic trade. Social: how people lived together, such as family structure, religion or the growth of slavery. Put each example in one column before you write about it.

Then write a full sentence: "The House of Burgesses, which began meeting in 1619, was a political development because it created an elected assembly that shared in making laws for Virginia." The sentence names the item, the date, the type and the reason. If a question asks for a political development and you describe how tobacco was grown, the answer sits in the wrong column. Practice using a short verb phrase for each, such as "created", "limited" or "shared", to show the change in power.

Worked example

Choose and justify a political development for 1607 to 1753.

1. Pick a body or agreement, such as the House of Burgesses.
2. Give the date range check: 1619 falls inside 1607 to 1753.
3. Describe it: it was a representative assembly in Virginia.
4. Add effect if asked: it gave colonists a model for local self-government.

Mental model: Name the type of development before choosing the example.

Common trap: Describing a famous colonial event that is economic when asked for political.

3. Debt, tea and pamphlets

Learning goal: Explain an effect of the Seven Years' War and group-specific responses to imperial policy.

Britain won the Seven Years' War in 1763 and carried large debt. The Proclamation of 1763 tried to limit colonial settlement west of the Appalachians. Parliament then passed taxes such as the Sugar Act and the Stamp Act. The 2025 SAQ expected a cause-and-effect link from the war to these policies.

Part C asked how a group responded to debates over colonists' rights from 1765 to 1783. The Chief Reader reported difficulty identifying specific groups. Saying that colonists protested is vague. Naming the Sons of Liberty and their public protests is stronger. Women also played a significant role in the non-importation movement by controlling household spending and producing goods to replace British imports.

A group answer has three parts: who, what they did, and why it responded to the rights debate. The last part is where the point is earned.

Build a cause-and-effect chain from the war to the protests. Britain won the Seven Years' War, which left it with large debt. Officials sought revenue from the colonies and tried to manage western settlement. Colonists objected that taxes passed without their consent violated their rights, and protests followed. Each link has a verb, and each can be a sentence in an essay.

For group responses, give a three-part answer. Merchants who signed non-importation agreements chose to stop buying British goods to pressure Parliament. Women who made cloth at home reduced demand for imports and made the boycott work. The Sons of Liberty organized public protests against the Stamp Act. In each case, say who, what they did and how it connected to the debate over rights and representation. Avoid sweeping statements about all colonists, since groups responded in different ways and some stayed loyal to Britain.

Worked example

Write one specific group response that links to rights.

1. Name the group: Sons of Liberty.
2. State the action: they organized public protests against the Stamp Act.
3. Explain why: they argued Parliament taxed them without their consent.
4. Check date: 1765 is within the prompt window.

Mental model: Group, action, link to rights.

Common trap: Naming the policy but not the group.

4. Writing the rules twice

Learning goal: Compare historians' arguments about early politics and keep evidence inside the period.

The first government of the United States under the Articles of Confederation was weak by design. The Constitution of 1787 created stronger national powers. Within a decade Federalists, led by figures such as Alexander Hamilton, and Democratic-Republicans, linked to Thomas Jefferson, argued over federal power. Federalists supported a national bank. Jefferson's party criticized broad federal power, yet Jefferson proceeded with the Louisiana Purchase in 1803 despite his strict reading of the Constitution and his concern that it contained no provision empowering him to buy territory.

The 2025 first SAQ gave two historians' arguments about early national politics and asked for a difference, evidence supporting one, and evidence supporting the other. Part B average score was 0.27 out of 1. The Chief Reader said students found evidence but struggled to explain how it supported an argument, and some cited out-of-period examples such as Andrew Jackson giving voting rights.

Run a period check. The prompt covered political developments to 1820. Jackson's presidency began in 1829, so it sits outside. Then explain: evidence plus a because clause that links it to the claim.

Run the period check as a routine. Before using an example, ask: does it fall inside the dates in the prompt? Andrew Jackson's presidency starts in 1829, so it would not support a claim about politics in the 1790s. Next, ask what the historian's argument says. If one historian says early politics were driven by fear of concentrated power and another says it was driven by economic interests, your evidence should fit one of those claims.

A short model: "Hamilton's national bank supports the argument that Federalists wanted a stronger national government, because it extended federal economic power. Jefferson's party criticized such broad powers, which shows a different view of the Constitution." Then explain the link in a final sentence. Writing the connection explicitly is the step that earns the point, so never leave evidence standing without a sentence that shows how it supports the claim. If you are unsure about a date, choose a different example rather than guess.

Worked example

Use the Louisiana Purchase as evidence for a claim that Democratic-Republicans used federal power expansively.

1. Date check: 1803 is inside the period.
2. Fact: Jefferson's administration bought Louisiana from France.
3. Link: the Constitution does not explicitly authorize buying territory, yet the executive acted anyway.
4. Sentence: the purchase supports the claim because it used federal power in a way that departed from strict limits.

Mental model: Date check, then because.

Common trap: Listing an example without checking its date.

5. Markets, ballots and a new sound

Learning goal: Connect the market revolution, expanding white male suffrage and reform movements in 1800 to 1848.

The Erie Canal opened in 1825 and lowered freight shipping costs. Factories and wage labor changed work, especially in the Northeast. Debates over internal improvements belong to this era. The 2025 Chief Reader report recommends the CED optional source, John Quincy Adams's letter to John McLean on internal improvements; it does not identify that letter as a source used in the exam question.

Politically, the expansion of voting rights for white men included removing property qualifications, which widened the electorate. Expanded white male voting rights did not mean universal suffrage: racial and gender restrictions remained. Treating democracy as simply expanding misses the way rights narrowed for some groups.

The Second Great Awakening influenced moral and social reforms. Reform movements in this era included temperance, antislavery activism and women's rights. The Seneca Falls Convention in 1848 gave a public declaration of women's rights. Always attach each development to a cause and a consequence.

Connect cause to effect for the Erie Canal in an invented outline. Cheaper transport lowered the cost of moving goods and farm produce between regions, so farmers could sell farther away and cities could grow. Growing markets encouraged specialization and factory production, which changed how people worked. Each step is a cause-and-effect link and can be written as a sentence with because.

For politics, remember that wider voting for white men did not extend to women or most Black Americans. The era of reform gave rise to temperance and antislavery movements, partly through religious revival, which motivated many people to see social problems as moral duties. Seneca Falls in 1848 brought together women who stated demands for rights. A good paragraph picks one development, names the cause, describes the change and names who gained or did not gain. A careful answer uses words such as "expanded for" instead of "expanded democracy" without qualification.

Worked example

Explain how the Erie Canal affected politics or economy.

1. Say what it is: a canal linking the Hudson River and the Great Lakes, completed 1825.
2. State the economic effect: lower shipping costs and stronger market links.
3. State a political effect: debates over who should pay for internal improvements.
4. Close with the link: transportation growth encouraged regional specialization and new political interests.

Mental model: Date, development type, effect.

Common trap: Mixing economic change with political change.

6. A country that kept splitting the difference

Learning goal: Trace compromises over slavery from 1820 to 1865 and avoid chronological blending.

The 2025 second SAQ gave a Daniel Webster speech on the Compromise of 1850. The Chief Reader reported that the most common misconception was misunderstanding the purpose of the speech, which promoted national unity. Another was assuming southern states widely discussed secession throughout the 1830s. A third was inaccurate chronology.

The Missouri Compromise of 1820 admitted Missouri as a slave state and Maine as a free state, and banned slavery north of the 36 degree 30 minute line in the rest of the Louisiana Purchase. After the Mexican-American War, new territory reopened the question. The Compromise of 1850 followed. The Kansas-Nebraska Act of 1854 introduced popular sovereignty and undermined the earlier line.

Split the period at 1848. Early debates were about balance of free and slave states. Later debates were about the status of territory taken from Mexico and then about whether federal law could stop slavery from expanding. Each compromise answered a regional difference over slavery and federal power.

Build a timeline in your head and sort each compromise into its question. 1820: how to balance free and slave states when Missouri sought admission. 1850: what to do with land taken from Mexico and how to handle a package of related issues. 1854: whether settlers in a territory should decide the question themselves, which replaced the earlier line. For each, write the problem, the solution and the weakness of the solution.

Test the weakness: the 1820 line held only as long as new territory fit the pattern. The 1850 package eased tension for a while but left strong disagreements. Popular sovereignty in 1854 invited conflict inside the territory itself. Notice how each solution handled a regional difference and left something unresolved. When writing, avoid placing events from the 1860s in a discussion of the 1830s. If the prompt asks about a source's purpose, ask who the speaker is, who the audience is and what the speaker wants them to do.

Worked example

Place popular sovereignty in the right sub-period and explain it.

1. Popular sovereignty let settlers decide slavery in a territory.
2. It is tied to the Kansas-Nebraska Act of 1854.
3. That date is after 1848.
4. So it belongs with the later period, when the debate was about territory from the Mexican-American War and beyond.

Mental model: Separate the sub-periods, then compromise answers regional differences.

Common trap: Blending 1820 events with 1850s debates.

7. Reconstruction is a political story first

Learning goal: Separate political effects from economic ones and explain how groups reacted to federal policy after 1865.

The Thirteenth, Fourteenth and Fifteenth Amendments abolished slavery, defined citizenship and protected the right to vote regardless of race. These are political developments. Southern states responded with Black Codes and, later, intimidation and violence by groups such as the Ku Klux Klan.

The 2025 fourth SAQ asked about Reconstruction and post-Reconstruction politics. The Chief Reader noted students often identified an economic development rather than a political one, struggled to name historically appropriate effects of the end of Reconstruction, and often failed to support a group's reaction with specifics. Overall mean score was 1.43 out of 3.

After 1877, federal troops left the South. Jim Crow laws, poll taxes and literacy tests limited Black political power. Sharecropping was an economic system, so it belongs under economics, though it affected politics through dependence. Match each example to what the prompt asks.

Use a three-column sort for Reconstruction examples. Political: the Fourteenth Amendment defined citizenship, the Fifteenth Amendment protected the right to vote regardless of race, and Black men were elected to office in the period. Economic: sharecropping, land access and wages. Social: schools, churches and family reunification. After 1877, political changes included the end of federal enforcement, and then laws and practices that limited voting.

For group reactions, specify who and what: formerly enslaved people formed institutions and voted; many white Southern officials passed Black Codes and used violence and intimidation to resist. Each reaction needs the group, the action and the connection to federal policy. When a prompt asks for an effect of the end of Reconstruction, say what changed after federal troops left, such as weaker protection for Black voters. Do not simply restate that Reconstruction ended. Check that the example fits the political category before you write it.

Worked example

Describe a political effect of the end of Reconstruction.

1. End date: 1877.
2. Name a policy: poll taxes or literacy tests.
3. Link to political change: they limited Black voting.
4. Check not economic: voting access is political.

Mental model: Match type of development to the prompt.

Common trap: Using sharecropping when asked for politics.

8. Gilded money, Progressive cleanup

Learning goal: Identify what Progressives wanted and how that changed politics.

After Reconstruction, industry, railroads and big cities grew fast, along with immigration and labor conflict. Reformers in the Progressive era (here dated to the 1890s through the 1920s) argued that government should regulate business, improve city life and widen political participation.

The 2025 SAQ reported that many students struggled to identify the goals of the Progressive movement and its influence on politics, economics and society. A goal is not a result. A goal might be breaking monopoly power or protecting consumers. A result might be the Pure Food and Drug Act or the Seventeenth Amendment's direct election of senators.

Women's suffrage activists used marches, lobbying and state campaigns. The Nineteenth Amendment, ratified in 1920, prohibited denying the right to vote on account of sex; some women already had voting rights under state law, and other barriers continued to prevent many women from voting. When you describe a group, keep the sequence: goal, action, result.

Practice the sequence goal, action, result with an invented set of notes. Goal: reformers wanted safer food and less corruption in city government. Action: they wrote exposes, organized campaigns and lobbied legislatures. Result: laws such as the Pure Food and Drug Act, and constitutional changes such as direct election of senators. Writing the three parts as separate sentences keeps goals from being confused with results.

Do the same for a labor or business example. Goal: limit monopoly power. Action: the government brought cases and passed regulations. Result: more oversight, though enforcement varied. Progressives did not all agree, and some reforms had limits or excluded groups. A balanced answer notes who benefited and who was left out. When asked about influence on politics, economics or society, choose the category the prompt names and name a specific policy or institution, not only the general idea of reform.

Worked example

Describe a Progressive goal and a result.

1. Pick a goal: regulate dangerous food production.
2. Pick an action: reformers publicized abuses.
3. Pick a result: the federal government passed food and drug regulation in 1906.
4. Check the label: it is an economic and social change with political cause.

Mental model: Goal, action, result.

Common trap: Listing results as goals.

9. Two wars, one crash and an argument about government

Learning goal: Explain isolationism, entry into war and the expansion of federal power in the Great Depression.

Between 1890 and 1945 the United States became a global power and then a government with larger domestic reach. The 2025 Set 1 fourth SAQ, Part C, asked students to explain how a group responded to debates about the role of the federal government from 1900 to 1945. Isolationists argued against entering World Wars I and II, which makes them a group with a clear stance.

The Great Depression pushed many voters to favor more federal action. The New Deal created relief and reform programs. The Social Security Act of 1935 is an example. The Chief Reader report describes the Democratic Party advocating more government involvement in response to the Great Depression and recommends comparing Democratic and Republican views during the New Deal.

A good answer picks a debate, names a group, and explains how that group acted. For example: isolationist sentiment helped produce the Neutrality Acts of the 1930s. Critics believed bankers and arms manufacturers had drawn the United States into World War I for profit, and wanted to avoid another war.

Frame the period as a debate over the size of the federal role. Early in the century, many reformers asked government to regulate business. In the Great Depression, many Americans looked to Washington for relief and economic help, and the New Deal created programs such as Social Security. Critics argued that federal power was growing too large and threatened individual liberty and local control. Both views are groups with arguments you can name.

For foreign policy, write a similar line of reasoning. Isolationists argued that the nation should stay out of European conflicts. After World War I, many believed that the United States had been drawn in by outside interests, and Neutrality Acts followed. Later events changed public opinion, but the debate shows how a group's position led to a policy. An essay should name the group, state its view and then link the view to a result, with dates that stay inside the prompt's years.

Worked example

Explain how one group responded to a debate over entering World War I.

1. Pick group: isolationists or anti-war groups.
2. Name the action: lobbied against entering the war.
3. Add reason: they feared costs and entanglement.
4. Check the era: the debate was in 1914 to 1917.

Mental model: Debate, group, action.

Common trap: Describing the war without a group response.

10. From containment to now: argue like a historian

Learning goal: Use the Cold War and later developments to practice evaluating extent and writing a complete argument.

From the late 1940s, containment guided U.S. foreign policy toward the Soviet Union. At home, the civil rights movement challenged segregation. The Supreme Court decided Brown v. Board of Education in 1954, and Congress passed the Civil Rights Act of 1964 and Voting Rights Act of 1965. Later decades included debates over federal power, immigration and economic change.

The 2025 Chief Reader report's DBQ comments emphasized that better responses understood how the question was framed. For prompts that say evaluate the extent to which, you must take a position on how much, not only whether. Practice with Venn diagrams and timelines for continuity and change.

The report also advised teachers to separate describe and explain. Describe gives characteristics. Explain gives a cause or reason. A strong essay includes a claim, context, evidence and reasoning that connects evidence to the claim.

Use an invented prompt to practice the extent skill: "Evaluate the extent to which the federal government changed the lives of Black Americans between 1945 and 1965." A weak response says yes or no. A better response says: to a significant extent in law, because Brown and the Civil Rights Act of 1964 changed legal rules, but to a smaller extent in daily life where enforcement and local practice lagged. The claim has a degree and a reason.

Next, add context, such as the Cold War setting in which segregation hurt the country's image, and evidence, such as the named laws and cases. Then connect each piece of evidence to the claim with a sentence. Finish with continuity and change: what changed, and what stayed the same. For describe, give characteristics. For explain, give causes. Use a short timeline to make sure your examples are in order and in range.

Worked example

Write an extent thesis about Brown v. Board.

1. State the decision: 1954 Supreme Court ruling that school segregation was unconstitutional.
2. Choose a degree: it was important but limited.
3. Give a reason: enforcement relied on later action.
4. Combine into one sentence.

Mental model: Claim, context, evidence, reasoning.

Common trap: Stating a claim with no degree.

11. A war measure that changed the war

Learning goal: Explain what the Emancipation Proclamation did and did not do, and why it changed the character of the Civil War.

President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863. The National Archives quotes its central statement: that "all persons held as slaves" within the rebellious areas "are, and henceforward shall be free." To understand the document, start with the war aims. The Archives explains that the Civil War was initially fought by the North to prevent the secession of the Southern states and preserve the Union. Sectional conflict over slavery had been a major cause of the war, but ending slavery was not a goal of the war.

That changed on September 22, 1862, when Lincoln issued a Preliminary Emancipation Proclamation, stating that enslaved people in states or parts of states still in rebellion on January 1, 1863 would be declared free. One hundred days later, with the rebellion continuing, he issued the final proclamation. The Archives says it came a few days after the Union victory at Antietam, and describes Lincoln's hopes: to inspire Black people, and especially enslaved people in the Confederacy, to support the Union, and to keep England and France from recognizing and aiding the Confederacy.

Because it was a military measure, the proclamation was limited. It applied only to states that had seceded, which left slavery untouched in the loyal border states. It expressly exempted parts of the Confederacy that were already under Union control. Most importantly, the freedom it promised depended on Union military victory. The Archives states directly that it did not end slavery in the nation.

Even so, it transformed the war. After January 1, 1863, every advance of federal troops expanded the domain of freedom. The proclamation announced the acceptance of Black men into the Union Army and Navy, and by the end of the war almost 200,000 Black soldiers and sailors had fought for the Union. In an argument, pair the limits with the effects, and avoid claiming either that it freed all enslaved people or that it changed nothing.

Worked example

A student writes that the Emancipation Proclamation ended slavery throughout the United States on January 1, 1863. Correct the claim using the National Archives description.

1. The Archives says the proclamation applied only to states that had seceded.
2. It left slavery untouched in the loyal border states and exempted some Union-held areas.
3. The promised freedom depended on Union military victory.
4. The Archives states that it did not end slavery in the nation, though it changed the character of the war.

Mental model: A limited military measure that still changed the war: new war aim, new soldiers, expanding freedom with each Union advance.

Common trap: Claiming it ended slavery everywhere, or that it had no effect.

12. Overruling Plessy: the Brown decision

Learning goal: Explain the holding of Brown v. Board of Education, its constitutional basis and the debate over its method.

In Brown v. Board of Education of Topeka, decided May 17, 1954, the Supreme Court ruled that separating children in public schools on the basis of race was unconstitutional. The National Archives says it overruled the "separate but equal" principle set forth in Plessy v. Ferguson, which the Court had adopted nearly 60 years earlier. Chief Justice Earl Warren delivered the unanimous ruling. The Court held that state-sanctioned segregation of public schools violated the Fourteenth Amendment.

The decision came in two steps. After the 1954 ruling, the Court heard further arguments on how to impose it. On May 31, 1955, Warren read the unanimous decision known as Brown II, instructing the states to begin desegregation plans "with all deliberate speed." The Archives describes this wording as careful but vague, and it notes considerable resistance to the ruling.

The Archives also records the debate about method. Some constitutional scholars felt the decision went against legal tradition by relying heavily on data supplied by social scientists instead of precedent or established law. Supporters of judicial restraint believed the Court had overstepped its powers by essentially writing new law. Proponents of judicial activism believed the Court had properly used its position to adapt the Constitution to new problems. Minority groups and members of the civil rights movement were buoyed by the decision, even without specific directions for implementation.

The Archives adds that the Warren Court stayed on this course for 15 years, deciding cases affecting race relations, the administration of criminal justice, the operation of the political process and the separation of church and state. When you write about Brown, give the holding, the constitutional basis, the implementation problem and one side of the debate about the Court's role. Name the case it overruled, and quote the phrase "all deliberate speed" correctly.

Worked example

Explain why the phrase "with all deliberate speed" is important in the history of Brown.

1. Brown II (May 31, 1955) instructed states to begin desegregation plans "with all deliberate speed".
2. The Archives describes the wording as careful but vague.
3. Without a fixed timetable, there was considerable resistance to the ruling.
4. So the phrase shows how a clear principle in 1954 met a slow and contested implementation.

Mental model: Brown I ruled segregation in public schools unconstitutional; Brown II set a vague timetable that met resistance.

Common trap: Saying Brown ended school segregation immediately.

13. Passing the Civil Rights Act of 1964

Learning goal: Explain what the Civil Rights Act of 1964 did and how supporters overcame the obstacles to passing it.

The National Archives describes the Civil Rights Act of 1964 as the most sweeping civil rights legislation since Reconstruction. President Lyndon Johnson signed it on July 2, 1964. It prohibited discrimination in public places, provided for the integration of schools and other public facilities, and made employment discrimination illegal. The Archives specifies that it outlawed segregation in businesses such as theaters, restaurants and hotels, banned discriminatory employment practices and ended segregation in public places such as swimming pools, libraries and public schools.

The origin matters. In a televised address on June 6, 1963, President John F. Kennedy urged the nation to guarantee equal treatment regardless of race and proposed legislation on voting rights, public accommodations, school desegregation and nondiscrimination in federally assisted programs. After Kennedy's assassination in November 1963, his proposal culminated in the act.

Passage was difficult. Opponents in the House bottled up the bill in the Rules Committee. In early 1964, House supporters overcame this by threatening to send the bill to the floor without committee approval. In the Senate, Southern Democratic opponents tried to talk the bill to death in a filibuster. The Archives credits the floor leadership of Senator Hubert Humphrey, the support of President Johnson and the efforts of Minority Leader Everett Dirksen, who convinced enough Republicans to support the bill over Democratic opposition. The compromise bill passed the Senate 73 to 27.

Title VII created the Equal Employment Opportunity Commission (EEOC) to implement employment provisions. In an answer, link the law to its causes (a presidential call for action), its obstacles (the committee and the filibuster) and its effects (public accommodations and employment). Note that support and opposition did not follow a single party line, which the Archives's account of Republican and Democratic roles shows.

Worked example

The Senate passed the compromise bill 73 to 27. What fraction of the senators voting supported it, as a percentage?

1. The votes were 73 for and 27 against, for 100 votes.
2. 73 / 100 = 0.73.
3. That is 73 percent of the votes cast.
4. The Archives notes that the support crossed party lines, since enough Republicans backed the bill over Democratic opposition.

Mental model: The act banned segregation in public accommodations and employment discrimination, and passed after the committee and filibuster obstacles.

Common trap: Describing the law as the work of a single party or a single leader.

14. Continuity and change across 101 years

Learning goal: Compare the Emancipation Proclamation and the Civil Rights Act of 1964 using continuity and change.

AP U.S. History often asks for continuity and change over time. Two National Archives documents give a good pair: the Emancipation Proclamation (January 1, 1863) and the Civil Rights Act of 1964 (July 2, 1964). The gap is 101 years, and each took a different path to a different kind of result. The Archives also calls the 1964 act the most sweeping civil rights legislation since Reconstruction, which links the two.

Start with the source of power. The Emancipation Proclamation was a military measure issued by the President as Commander-in-Chief during a rebellion. The 1964 act was a statute passed by Congress, signed by the President and enforced in part by a new body, the EEOC. One came from executive war power, the other from the ordinary legislative process, with committee and filibuster obstacles.

Next, compare scope. The proclamation applied only to states in rebellion, left slavery in the loyal border states untouched and depended on Union victory. The 1964 act covered public accommodations such as theaters, restaurants and hotels, public places and schools, and employment practices. Its scope was national in its list of covered settings, though its effects depended on enforcement and resistance.

Then find continuity. Both responded to pressure and events: the war and the actions of enslaved people in the first case, and a national address and a broad movement in the second. Brown v. Board, decided between them in 1954, shows the same pattern of a stated principle followed by resistance and gradual enforcement. A good comparison states one clear change, one clear continuity and the evidence for each. Avoid claiming that either document by itself finished the struggle for equality.

Worked example

Write one claim of change and one of continuity comparing the Emancipation Proclamation and the Civil Rights Act of 1964.

1. Change: the 1863 measure was issued by the President as a war measure, while the 1964 act was passed by Congress through the legislative process.
2. Evidence for change: the Archives calls the first a military measure and describes the House Rules Committee and Senate filibuster for the second.
3. Continuity: both responded to pressure from events and movements, and both met limits or resistance in practice.
4. Evidence for continuity: the proclamation depended on Union victory; the Archives notes resistance to civil rights decisions and the need for an enforcement body.

Mental model: Compare source of power, scope and enforcement, then name one change and one continuity.

Common trap: Treating either document as the end of the struggle.
