1607 - 1800

Colonization & the founding era

Event	Significance

1800 - 1877

Expansion, division, and Civil War

Manifest Destiny: The 19th-century belief that the US was destined to expand across North America, driving westward settlement.
Missouri Compromise (1820): Attempted to balance free and slave states as the nation expanded west - one of several failed compromises over slavery.
Civil War (1861-1865): Fought between the Union and the Confederacy primarily over slavery and states' rights; ended with the Union's victory and slavery's abolition.
Emancipation Proclamation (1863): Declared enslaved people in Confederate states free; the 13th Amendment (1865) abolished slavery nationwide.
Reconstruction (1865-1877): The postwar period of rebuilding the South and integrating formerly enslaved people, which ended with the withdrawal of federal troops.

1877 - 1920

Industrialization & reform

Event / Movement	Significance
Gilded Age	Rapid industrialization and wealth inequality in the late 1800s; rise of monopolies (Rockefeller, Carnegie)
Progressive Era	Early 1900s reform movement targeting corruption, labor conditions, and public health
19th Amendment (1920)	Granted women the right to vote after decades of suffrage activism

1920 - present

20th century & beyond

The Great Depression (1929-1939): Severe economic collapse following the 1929 stock market crash; the New Deal under FDR expanded the federal government's role in the economy.
World War II (1941-1945, US involvement): The US entered after the attack on Pearl Harbor; emerged as a global superpower afterward.
Cold War (1947-1991): Decades-long geopolitical tension between the US and Soviet Union, fought through proxy conflicts, an arms race, and the Space Race rather than direct war.
Civil Rights Movement (1950s-1960s): Campaign to end racial segregation and discrimination, led by figures like Martin Luther King Jr.; resulted in the Civil Rights Act (1964) and Voting Rights Act (1965).

Common Mistakes

Where students go wrong in US history

Patterns we see again and again in student work. Each one is fixable once you know to look for it.

Memorizing amendments and acts without their context: Knowing that the 14th Amendment guarantees equal protection is a fact. Knowing that it was passed during Reconstruction, that it was largely ignored for decades, and that it became the basis for Brown v. Board of Education a century later is an understanding. Exams test the second one.
Treating the Civil War as a single-cause event: Slavery was the central cause, and answers that dodge that lose marks. But strong answers also explain the mechanisms: sectional economics, the fight over new territories, the collapse of compromise, and the 1860 election. Learn the chain, not just the endpoint.
Skipping the "why now" question: Why did the civil rights movement accelerate in the 1950s and 1960s rather than earlier? Why did Progressivism emerge when it did? Every major movement has timing that depends on what came before, and "why then" is one of the most common essay prompts.
Confusing similar-sounding people and documents: Articles of Confederation versus the Constitution. Federalists versus Anti-Federalists versus the later Federalist Party. Two Roosevelts, two Adamses, two Johnsons. Make a deliberate comparison card for each pair the first time you meet them, before they blur.
Not reading primary sources: Document-based questions are a large part of most US history exams. Practice reading a short primary source and answering: who wrote it, for whom, when, and what were they trying to achieve? That four-part habit is most of the skill.
