Want to understand us history without memorizing endless dates? Start with a few turning points: independence, the Constitution, the Civil War, the Great Depression and civil rights. This guide walks through them in order.
| Milestone | Year |
|---|---|
| Declaration of Independence | 1776 (year) |
| Constitution of the United States | 1787 (year) |
| Bill of Rights | 1791 (year) |
| Louisiana Purchase Treaty | 1803 (year) |
| Emancipation Proclamation | 1863 (year) |
| Civil Rights Act | 1964 (year) |
Years in the table follow document titles on the National Archives milestone documents page, which was last reviewed on August 3, 2022. Figures and groupings can change, so check the source before you rely on them.
How did the founding era create a new nation?
The usual starting point is the Declaration of Independence, dated 1776 on the National Archives milestone documents page. The Archives files it under Revolution and the New Nation, a group spanning 1754 to the 1820s. The american revolution timeline covers the war itself in more depth.
The Declaration asserted the colonies’ freedom from British rule and introduced ideals such as liberty and justice. A Timetoast timeline adds that those principles were initially limited to white, land-owning men, a paradox that would fuel later social and civil rights movements. The declaration of independence summary walks through the text in plain language.
Independence did not settle how to govern. An American Public Square timeline describes the Articles of Confederation as proving to be a failure, and it dates the Constitution to 1787. For a closer look at the document, see us constitution explained.
The National Archives list marks the first years under the new government with these documents:
- Virginia Plan (1787) and Northwest Ordinance (1787)
- President George Washington’s First Inaugural Speech (1789)
- Federal Judiciary Act (1789)
- Bill of Rights (1791)
The Bill of Rights closes that run, and the bill of rights summary explains the rights it protects. The American Public Square timeline also marks the Whiskey, or anti-tax, rebellion of 1791 to 1794.
Expansion and reform in the early republic
The Archives’ Expansion and Reform group spans 1801 to 1861, and its documents show a country growing in size and in conflict. At its center is the Louisiana Purchase Treaty of 1803, and the louisiana purchase facts page has the details. The milestone list also includes these documents:
- Patent for Cotton Gin (1794)
- Jefferson’s Secret Message to Congress Regarding the Lewis and Clark Expedition (1803)
- Missouri Compromise (1820)
- Monroe Doctrine (1822)
- Treaty of Guadalupe Hidalgo (1848)
Expansion carried a human cost. According to an American Public Square factsheet, President Jackson signed the Indian Removal Act, which authorized the forced removal of Native Americans living in the eastern part of the country to lands west of the Mississippi River, and by the late 1830s the Jackson administration relocated nearly 50,000 Native Americans. A Timetoast entry dates the act to May 28, 1830 and links it to the Trail of Tears.
Civil War and Reconstruction
The Archives’ Civil War and Reconstruction group runs from 1850 to 1877, and its early documents trace the road to the Civil War: the Compromise of 1850, the Kansas-Nebraska Act (1854) and Dred Scott v. Sandford (1857). The causes of the civil war page explains the tensions behind them. Both are listed on the National Archives page.
The Archives marks the war’s start with the telegram announcing the surrender of Fort Sumter (1861), and an American Public Square timeline lists the Civil War as 1861 to 1865. The Emancipation Proclamation is dated Jan 1, 1863 on Timetoast, which says it declared all enslaved people in Confederate states free. It did not immediately free everyone, but it reframed the war as a fight for human freedom.
That same year, the Archives list records War Department General Order 143, which created the U.S. Colored Troops (1863). Reconstruction then brought three constitutional changes, marked in the same list:
- 13th Amendment: abolition of slavery (1865)
- 14th Amendment: civil rights (1868)
- 15th Amendment: voting rights (1870)
The Timetoast timeline summarizes these amendments as abolishing slavery, granting citizenship and extending voting rights to Black men, while noting that many states quickly enacted laws to undermine them. The American Public Square timeline dates the end of Reconstruction to 1877.
Industrial growth and modern America in us history
The Archives sorts this era into The Development of the Industrial United States, which spans 1870 to 1900, and The Emergence of Modern America, which spans 1890 to 1930. Together they show a country of new inventions, new regulation and new fights over who counts as a full citizen. Key entries on the National Archives list include:
- Thomas Edison’s Patent Application for the Light Bulb (1880)
- Chinese Exclusion Act (1882)
- Sherman Anti-Trust Act (1890)
- Plessy v. Ferguson (1896)
- 16th Amendment: federal income tax (1913)
- Zimmermann Telegram (1917)
- 19th Amendment: women’s right to vote (1920)
Labor and migration shaped the same decades. A Timetoast timeline says the Pullman Strike of 1894 became a national labor issue when federal troops intervened, and that the NAACP formed on Feb 12, 1909 in response to escalating racial violence. It also dates the Great Migration to 1916, when millions of African Americans moved from the rural South to urban areas in the North.
War also changed the country’s role in the world. The American Public Square timeline lists the Spanish American War in 1898 and U.S. involvement in World War I from 1917 to 1918. The Archives list adds President Woodrow Wilson’s 14 Points (1918).
The Great Depression and World War II
The Archives’ Great Depression and World War II group covers 1929 to 1945, and the great depression summary explains the economic collapse behind it. Its New Deal documents include the Tennessee Valley Authority Act (1933) and the Social Security Act (1935), both on the National Archives list. A Timetoast timeline says the New Deal addressed economic collapse with policies that created jobs and improved public infrastructure.
Hardship reached Washington itself in 1932. An American Public Square timeline describes a gathering of probably 10,000 to 25,000 World War I veterans, with estimates varying widely, who came to demand immediate payment of their wartime bonus.
World War II then reshaped the federal government and the country. The Archives list includes:
- Lend-Lease Act (1941)
- Executive Order 8802, prohibiting discrimination in the defense industry (1941)
- Joint Address to Congress leading to a declaration of war against Japan (1941)
- Executive Order 9066, resulting in Japanese-American internment (1942)
- Servicemen’s Readjustment Act (1944)
- Surrender of Germany (1945) and Surrender of Japan (1945)
- United Nations Charter (1945)
The American Public Square timeline describes Executive Order 9066 as an order authorizing the evacuation of all persons deemed a threat to national security from the west coast to relocation centers further inland. Readers interested in the people who served can explore military and veterans.
What changed in postwar America and the civil rights era?
The Archives’ Postwar United States group runs from 1945 to the early 1970s, and an American Public Square timeline dates the Cold War to 1947 through 1991. The National Archives list includes the Truman Doctrine (1947), the Marshall Plan (1948), the order establishing the Peace Corps (1961) and the Medicare and Medicaid Act (1965).
The same list charts the legal turning points of the civil rights movement, and the civil rights movement timeline gives the full sequence. In order:
- Executive Order 9981: desegregation of the armed forces (1948)
- Brown v. Board of Education (1954)
- Executive Order 10730: desegregation of Central High School (1957)
- Official Program for the March on Washington (1963)
- Civil Rights Act (1964)
- Voting Rights Act (1965)
Timetoast adds that Brown v. Board of Education, dated May 17, 1954, ruled segregation in public schools unconstitutional and overturned Plessy v. Ferguson. It dates the March on Washington to Aug 28, 1963 and the Americans with Disabilities Act to Jul 26, 1990.
The Archives page, last reviewed on August 3, 2022, says its original list included only documents created prior to 1965. The American Public Square timeline carries on to later events, including the September 11 attacks of 2001 and the Great Recession of 2008. For the people behind these dates, the patriotic stories collection is a good next stop.
Frequently asked questions
Where should I start with us history?
Show answer
A practical start is the National Archives milestone list, which grew out of the project Our Documents: 100 Milestone Documents from the National Archives. Read it group by group, from Revolution and the New Nation through Postwar United States. The page was last reviewed on August 3, 2022.
Where does a timeline of us history begin?
Show answer
It depends on the author. The American Public Square timeline begins with the Declaration of Independence in 1776. A Timetoast timeline begins earlier, with the arrival of Columbus and the beginning of colonization, and labels that period 1492 to 1764.
Why do some timelines show different dates?
Show answer
Sources can disagree, so compare them. The American Public Square timeline lists the Emancipation Proclamation under 1861 and the Voting Rights Act under 1956, while the National Archives list dates them to 1863 and 1965. When dates conflict, check the original document.
How can I read a timeline critically?
Show answer
The American Public Square factsheet offers a useful question: how does an individual’s race, identity, and/or socio-economic status influence how that individual was impacted by these events? Asking it for each date turns a list of facts into a more complete story.
