American History on the citizenship test

The history questions cover 400 years, but the test only wants the highlights: names, events, and one-line reasons. You never need an essay, a full timeline, or more than a handful of dates. This guide walks the three official eras in order, teaches exactly what the questions ask, and flags where the two test versions differ. It is part of our citizenship test study guide.

How big this topic is

Both official lists split American History into the same three eras. The 2025 list goes deeper in every era:

Colonial period and independence

The story starts before the colonies: American Indians (Native Americans) lived in America before the Europeans arrived, and Africans were taken to America and sold as slaves. Colonists came for freedom, political liberty, religious freedom, and economic opportunity, and later fought the British over high taxes (taxation without representation), soldiers quartered in their houses, and the lack of self-government.

The founding facts are the core of this era: Thomas Jefferson wrote the Declaration of Independence, adopted on July 4, 1776. The Constitution was written in 1787 at the Constitutional Convention, and the Federalist Papers (written by Madison, Hamilton, and Jay under the name Publius) supported its passage. George Washington is the Father of Our Country and the first President. There were 13 original states: the 2008 test asks you to name three of them, the 2025 test asks for five.

Version note: the 2025 list adds a "famous for" set covering Benjamin Franklin, Washington, Jefferson, Madison, and Hamilton, plus questions naming the American Revolution and its major events, such as the Declaration itself, Valley Forge, and the British surrender at Yorktown.

The 1800s

The smallest era on both lists, anchored by two things. First, the Louisiana Territory, which the United States bought from France in 1803. Second, the Civil War, the war between the North and the South. Know one problem that led to it (slavery, economic reasons, or states' rights) and what Abraham Lincoln did: freed the slaves through the Emancipation Proclamation, saved the Union, and led the country through the war. The Emancipation Proclamation freed slaves in the Confederacy.

The century's other wars make a single question on both lists: the War of 1812, the Mexican-American War, the Civil War, and the Spanish-American War; you name one. For the women's rights movement, the 2008 list asks what Susan B. Anthony did (fought for women's rights), while the 2025 list asks you to name one movement leader and accepts Anthony, Elizabeth Cady Stanton, Sojourner Truth, Harriet Tubman, and others.

Version note: the 2025 list also asks which war ended slavery (the Civil War), about Civil War events such as Gettysburg and Appomattox, and about two amendments: the 14th (everyone born or naturalized in the United States is a citizen) and the 15th (all men got the right to vote after the Civil War, in 1870).

Recent American history

The 1900s questions follow the wars. The United States fought five in that century: World War I, World War II, the Korean War, the Vietnam War, and the Persian Gulf War. Franklin Roosevelt was President during the Great Depression and World War II, and Dwight Eisenhower was a general in World War II before becoming President. On the 2008 list, you also need Woodrow Wilson as the World War I President and Japan, Germany, and Italy as the World War II enemies.

After the wars come the Cold War, where the main U.S. concern was communism; the civil rights movement, which fought to end racial discrimination, led by Martin Luther King, Jr.; and September 11, 2001, when terrorists attacked the United States. Both lists also ask you to name one American Indian tribe, such as the Cherokee or Navajo.

Version note: the 2025 list asks why the United States entered each conflict: Germany attacked U.S. ships (World War I), the Japanese attacked Pearl Harbor (World War II), and stopping the spread of communism (Korea and Vietnam); the Gulf War answer is forcing the Iraqi military out of Kuwait. It adds the Soviet Union as the Cold War rival, the Great Depression (the longest economic recession, started by the 1929 stock market crash), when women got the right to vote (1920, the 19th Amendment), post-2001 conflicts, and one question on American innovations, from the light bulb to landing on the moon.

How to study this topic

Study chronologically: colonial period, then the 1800s, then the 1900s. The eras connect (independence leads to the Constitution, slavery leads to the Civil War, the wars lead to the Cold War), and that storyline is what makes the answers stick. One advantage of this topic: nothing in it changes with elections, so whatever you learn now stays correct through your interview.

Read the official questions for your version with answers and explanations: the 2008 history sections or the 2025 history sections. Then quiz yourself out loud, era by era, until the names and reasons come from memory.

Frequently asked questions

How many American History questions are on the citizenship test?

It is the second-largest topic. The 2008 test draws 30 of its 100 questions from American History (13 on the colonial period and independence, 7 on the 1800s, 10 on recent history). The 2025 test draws 46 of its 128 (17, 10, and 19). If you are on the 2025 test, history deserves noticeably more of your time.

What history dates do I need to memorize?

Very few. On the 2008 list the official answers include only three dates: July 4, 1776 (Declaration of Independence adopted), 1787 (Constitution written), and 1803 (Louisiana Purchase). The 2025 list adds 1870 (all men get the right to vote, 15th Amendment), 1920 (women get the right to vote, 19th Amendment), and 1929 (the Great Depression begins). Everything else is names, events, and reasons.

Do I need to know all 13 original states?

No. The 2008 test asks you to name three of the 13 original states, and the 2025 test asks for five. The official answers list all 13, so pick a handful you can say quickly and confidently, for example the ones you can locate on a map, and practice those.

How is the 2025 history section different from the 2008 one?

It is half again as large: 46 questions instead of 30. The 2025 list adds a set of questions about what individual founders are famous for (Franklin, Washington, Jefferson, Madison, Hamilton), more reasoning questions such as why the United States entered each war, and new facts like the 14th and 15th Amendments, the Great Depression, and post-2001 conflicts. Study only your version's list.

Do the history answers ever change?

No. Unlike the American Government topic, where officeholder answers change with elections, every history answer is fixed. That makes this topic ideal to study early: once you learn it, it stays learned, and you can spend your final pre-interview days on the changing answers instead.

Which presidents come up in the history section?

A short list. George Washington (Father of Our Country, first president), Thomas Jefferson (wrote the Declaration of Independence), Abraham Lincoln (Civil War, Emancipation Proclamation), Franklin Roosevelt (Great Depression and World War II), and Dwight Eisenhower (World War II general). The 2008 list also asks who was president during World War I (Woodrow Wilson), and the 2025 list adds James Madison, the Father of the Constitution.
