9.1 Contextualizing Period 9
Period 9 runs from 1980 to the present. It opens with a conservative revival led by Ronald Reagan and covers the end of the Cold War, a digital and global economy, new waves of immigration and the war on terrorism after September 11, 2001. Knowing where Americans stood in 1980 helps you explain everything that follows.
Key terms
- contextualization
- conservatism
- stagflation

- post–Cold War world
Where things stood in 1980
By 1980 many Americans had lost faith in the federal government. The Vietnam War had ended badly, and the Watergate scandal had forced President Nixon to resign in 1974. Stagflation, meaning high inflation and high unemployment at the same time, squeezed families; inflation hit about 13.5 percent in 1980. Iranian students had held 52 Americans hostage since November 1979, and the Soviet invasion of Afghanistan that December ended the thaw in Cold War tensions known as détente.
Meanwhile a conservative movement had been growing for decades. It drew on anticommunists, critics of big government and taxes, white suburban and Sun Belt voters, and newly active evangelical Christians. Ronald Reagan, a former actor and governor of California, united these groups and defeated President Jimmy Carter in 1980.
The big threads of Period 9
- Conservatism and the role of government: conservatives won lower taxes and less regulation, but popular programs like Social Security and Medicare survived, and debates over the safety net, trade and banking continued.
- The end of the Cold War: a U.S. military buildup, diplomacy with Soviet leader Mikhail Gorbachev and the Soviet Union's own collapse ended the Cold War by 1991. The U.S. then had to decide how to use its power as the only superpower.
- A new economy: computers, the internet and global trade raised productivity, while factory jobs and union membership declined and inequality grew.
- Demographic change: immigration from Latin America and Asia, and the continued shift of people to the South and West, changed culture and politics.
- The war on terrorism: after the September 11, 2001 attacks, the U.S. fought long wars in Afghanistan and Iraq and argued about security versus civil liberties.
Change and continuity with earlier periods
Many Period 9 developments grow out of Period 8. The rise of conservatism was partly a reaction against the Great Society and the cultural changes of the 1960s. The Immigration Act of 1965 made the new immigration from Asia and Latin America possible. Environmental laws of the 1970s set up later debates over climate change. Computer research funded during World War II and the Cold War laid the groundwork for the digital revolution.
Some patterns are much older. Debates over the size of government echo the Gilded Age and the New Deal. Arguments over immigrants and assimilation recall the nativism of the late 1800s and the 1920s. Rising inequality led some writers to call the 1990s and 2000s a 'second Gilded Age.'
How much of the exam this is
Period 9 carries only about 4–6 percent of the exam weight, tied with Period 1 for the smallest share. The DBQ covers only 1754–1980, so Period 9 shows up in multiple-choice questions, in short-answer questions (which reach only to 2001) and possibly as the later end of a broad long essay prompt. Focus on the big trends and key evidence rather than memorizing every event since 1980.

- Example 1
Writing contextualization for a Period 9 essay
Write a contextualization paragraph for this prompt: Evaluate the extent to which the Reagan administration changed the role of the federal government in the 1980s.
Show the solutionHide the solution
- Step 1: Context means the broader situation that came before or surrounded the topic. Reach back before 1981, not forward.
- Step 2: Pick two or three developments that explain why voters wanted a change: the expansion of government under the New Deal and Great Society, the loss of trust after Vietnam and Watergate, and the stagflation of the 1970s.
- Step 3: Add the rise of the New Right so the paragraph explains who backed Reagan.
- Step 4: End by connecting the context to the prompt's subject.
Answer: Model paragraph: Since the New Deal of the 1930s, and especially after Lyndon Johnson's Great Society of the 1960s, the federal government had taken on a large role in regulating business and fighting poverty. By the late 1970s, however, the Vietnam War and the Watergate scandal had badly damaged Americans' trust in government, and stagflation, with inflation over 13 percent in 1980, seemed to show that federal economic management was failing. A growing conservative movement of anti-tax activists, anticommunists and evangelical Christians in groups like the Moral Majority argued that big government was the problem. These frustrations helped Ronald Reagan defeat Jimmy Carter in 1980 on a promise to cut taxes, regulation and federal spending.
Common mistakes
- Writing context that comes after the prompt's time period. Context for a 1980s prompt should come from the 1960s and 1970s.
- Treating 1980 as a total break. Conservatism, Sun Belt growth and the new immigration all began well before 1980.
- Spending too much study time on Period 9. It carries the least weight of the later periods, so master Periods 3–8 first.
On the exam
- For contextualization, a few sentences on the 1970s crises and the rise of the New Right work for most Period 9 prompts.
- The long essay covers a broad stretch of the course, so be ready to carry a theme like civil rights or the role of government past 1980 as the end point of a long-term trend.
