On the evening of November 9, 1989, an East German spokesman, Günter Schabowski, announced new travel rules at a press conference. Asked when they took effect, he answered, in effect, that they took effect at once. Thousands of East Berliners went to the border crossings, and that night the guards opened the gates. Just over two years later, the Soviet Union itself was gone. A popular version of the story says one American speech brought down the wall. The real story has more causes, and that is what this period asks you to explain.
This lesson covers Period 9 of AP US History, from 1980 to the present. It is the most recent period, so the course asks what happened and what changed, not which side was right.
The big themes
- A conservative rise. Beliefs in traditional social values and a smaller role for government gained ground after 1980.
- Technology, economy and population. Computers and the internet transformed work, manufacturing declined, and migration reshaped the country.
- A new role in the world. The Cold War ended, and after 2001 foreign policy centered on fighting terrorism.
Reagan and conservatism
Ronald Reagan's win over Jimmy Carter in 1980 came amid inflation, unemployment and the Iran hostage crisis. Groups such as Jerry Falwell's Moral Majority brought evangelical voters into politics. Reagan cut income taxes in 1981, continued the deregulation of industries that had begun in the 1970s, and fired striking air traffic controllers. Conservatives argued that liberal programs did not reduce poverty or spur growth, but many programs, such as Social Security and Medicare, stayed popular. Debates over free trade, the safety net and financial reform continued: NAFTA (1994), the Contract with America (1994), welfare reform signed by Bill Clinton (1996), and later the Affordable Care Act (2010).
The end of the Cold War
Reagan opposed communism in speeches, built up nuclear and conventional forces, proposed the Strategic Defense Initiative, and backed anti-communist forces abroad. The Iran-Contra affair, revealed in 1986, exposed secret arms sales to Iran and aid to the Contras that Congress had banned. After Mikhail Gorbachev took power in 1985, the two leaders held summits and signed the INF Treaty in 1987. Most communist governments in Eastern Europe fell in 1989, and the Soviet Union dissolved in 1991. The US then led a coalition in the 1991 Gulf War and sent forces on peacekeeping missions, and Americans kept debating when to use military power.
A changing economy and population
Digital technology raised productivity and tied the US more closely to world markets. Service jobs grew while manufacturing jobs fell, union membership declined, and real wages stagnated for many working- and middle-class families as inequality grew. People kept moving to the South and West, raising the Sun Belt's political weight. Immigration from Latin America and Asia rose sharply, and the Immigration Reform and Control Act of 1986 paired legal status for many undocumented immigrants with penalties for employers. Debates over immigration, diversity, gender roles and family structures stayed intense, from the AIDS crisis to same-sex marriage.
Challenges of the 21st century
On September 11, 2001, al-Qaeda attacks killed nearly 3,000 people. The US went to war in Afghanistan in 2001 and invaded Iraq in 2003; both wars were long and contested. The PATRIOT Act and the new Department of Homeland Security aimed to improve security but raised questions about civil liberties and human rights. The Great Recession of 2007–2009 renewed arguments about regulating finance. Conflicts in the Middle East and concern about climate change fed debates over dependence on fossil fuels. Through all this, the US remained the world's leading superpower.
Common mistakes students make
- Saying Reagan alone ended the Cold War. Soviet economic problems, Gorbachev's reforms and Eastern European movements mattered too.
- Saying conservatives dismantled the New Deal. Taxes fell and regulation eased, but major programs survived.
- Linking Iraq to 9/11. The main stated case for the 2003 war was claimed weapons of mass destruction, and no stockpiles were found.
- Writing opinion instead of history. For recent events, explain causes and effects and use evidence, as with any period.
