7.1 Contextualizing Period 7
Period 7 runs from 1890 to 1945, a time when the United States became a world power and Americans debated how much government should do at home and abroad. Reform, two world wars, a decade of boom and the Great Depression all pushed the federal government to grow far beyond its Gilded Age role.
Key terms
- contextualization
- industrialization
- urbanization
- Progressive Era
- isolationism vs. internationalism
Where the period starts
By 1890 the U.S. had the world's largest industrial economy, giant corporations, crowded cities full of immigrants, and angry farmers and workers (Period 6). The 1890 census said the frontier was closed, and a severe depression began in 1893. Many Americans concluded that the old laissez-faire approach could not handle an industrial society, and that the country needed new markets overseas.
Those two conclusions drive this unit: reform at home and expansion abroad.
Three big debates
- Government's role in the economy and society: Progressives (1890s–1920) and the New Deal (1930s) expanded federal regulation and created a social safety net. The pro-business 1920s pulled back in between.
- America's role in the world: Americans argued over imperialism after 1898, entered World War I in 1917, rejected the League of Nations, tried to stay neutral in the 1930s, and then fought World War II as a global superpower in the making.
- National identity and culture: Who counted as a real American? This shaped immigration quotas in the 1920s, the Great Migration, the Harlem Renaissance, women's suffrage, and the clash between modern and traditional values.
A timeline to anchor you
| Years | Era | Big themes |
|---|---|---|
| 1890–1914 | Imperialism and the Progressive Era | Spanish–American War, muckrakers, trust-busting, 16th and 17th Amendments (1913) |
| 1914–1919 | World War I | Neutrality, entry in 1917, home-front controls, Treaty of Versailles fight, 18th and 19th Amendments |
| 1920–1929 | The 1920s | Consumer economy, mass culture, culture wars, immigration quotas |
| 1929–1941 | Great Depression and New Deal | Collapse, Hoover's limited response, FDR's New Deal, neutrality |
| 1941–1945 | World War II | Total mobilization, victory, the atomic bomb, the United Nations |
Continuities to watch
Not everything changed. Racial segregation stayed legal in the South for the whole period, and the federal government did little to stop lynching. Nativism ran from the Chinese Exclusion Act through the quota laws of the 1920s to the incarceration of Japanese Americans in 1942. And Americans kept arguing over the same basic question raised in the Gilded Age: should government protect ordinary people from economic power, or stay out of the way? Noticing these threads helps you write about continuity as well as change.
Where it ends
By 1945 the U.S. had the world's strongest economy and military, sole possession of the atomic bomb, and a leading role in the new United Nations. The federal government was much bigger and more involved in daily life than in 1890. A growing rivalry with the Soviet Union set up the Cold War of Period 8.
A useful way to use context is to note what Americans had learned by each turning point. For example, the failure of the League of Nations after World War I shaped the decision to join the United Nations in 1945.

Picking context that fits the prompt
Which developments would make the strongest contextualization for an essay on the causes of the New Deal, and why?
Show the solutionHide the solution
- Step 1: Context should explain the situation that made the New Deal possible or necessary, not the New Deal itself.
- Step 2: Good choices: the 1929 crash and economic collapse, Hoover's reliance on voluntary action, and earlier Progressive ideas about government regulation.
- Step 3: Weak choices: details of individual New Deal programs (those are evidence, not context) or unrelated events like the Scopes Trial.
Answer: The strongest context explains how the Great Depression (bank failures, roughly 25 percent unemployment by 1933) and the limits of Hoover's response created demand for bold federal action, and notes that Progressive Era reforms had already shown the federal government could regulate the economy. Then tie it to the prompt: these conditions set the stage for Franklin Roosevelt's New Deal.
Common mistakes
- Forgetting that Period 7 starts in 1890 and overlaps Period 6. Populism, the 1890s depression and Hawaii's annexation fit both.
- Treating the period as steady growth of government. The 1920s brought a pro-business retreat between Progressivism and the New Deal.
- Using events from the prompt itself as context. Context must be broader than the topic you are arguing about.
On the exam
- Period 7 is one of the most heavily tested periods. Questions often ask you to compare reform eras or the paths to the two world wars (7.15).
- For DBQ context, describe developments before the prompt's dates and connect them explicitly to the question.

"Up to our own day American history has been in a large degree the history of the colonization of the Great West. The existence of an area of free land, its continuous recession, and the advance of American settlement westward, explain American development. . . .
And now, four centuries from the discovery of America, at the end of a hundred years of life under the Constitution, the frontier has gone, and with its going has closed the first period of American history."

Turner's claim that "the frontier has gone" was based in part on
