APUSH Period 9 — 1980 to the Present: Positions and Trends

Period 9 of AP United States History covers 1980 to the present and carries between 4 and 6 percent of the exam. Its questions are usually about large trends and about the arguments Americans have made over them, so this material is organized around trends and positions, stated fairly on every side, rather than around individual politicians.

It begins with the political realignment of 1980: the coalition of evangelical Christians, economic conservatives and anticommunists that formed the New Right. Two economic trends follow: the weakening of organized labor, symbolized by the firing of the striking air traffic controllers in 1981, and the long shift from manufacturing toward services, finance and technology, with widening income inequality.

The end of the Cold War is treated through Reagan's combination of pressure and negotiation with Mikhail Gorbachev, which produced the INF Treaty, and through the several explanations historians give for the collapse of Soviet power between 1989 and 1991. The Persian Gulf War of 1991 shows the new era's first major conflict.

The 1990s and after are covered through their main debates: the North American Free Trade Agreement, with the case its supporters and its critics made; the welfare reform law of 1996; the Immigration Reform and Control Act of 1986 and the enforcement-versus-legalization argument that followed it; the response to the attacks of September 11, 2001, including the war in Afghanistan and the argument over the PATRIOT Act; the 2003 invasion of Iraq and its stated rationale; and the financial crisis of 2008 with the federal response.

The twelve quiz questions are built so that the right answer is a matter of record, not of opinion: what a law did, what each side argued, what historians cite. One question opens with a public-domain presidential source, Reagan's words in Berlin in 1987. The explanations add the context an essay needs.

The seventeen flashcards run from the Moral Majority to the Great Recession, with dates and significance.

The category's material on 1945 to the present already covers supply-side economics, the general shift in post-Cold War foreign policy, demographic change since 1965 and the debate over the federal government's role; this material fills in the rest of Unit 9, for class or for review before the May exam.
