Tensions carried over from the 1970s, including Cold War rivalry, stagflation, the Iranian Revolution, and the Soviet invasion of Afghanistan, created conditions for a sharp rightward political turn. Reagan and Thatcher championed supply-side economics and an aggressive posture toward the Soviet Union, while developing nations accumulated unsustainable debt.
The 1980s were defined by escalating US-Soviet confrontation, widespread adoption of free-market capitalism, the global recognition of the AIDS epidemic, and dramatic political upheaval across Eastern Europe. By 1989, popular uprisings had toppled several communist governments, and the Berlin Wall was torn down, signaling the end of the Cold War order.
The Soviet Union's weakened position following Gorbachev's reforms culminated in the August Coup of 1991 and the USSR's dissolution. Germany reunified, free-market economics spread globally, and the geopolitical balance shifted decisively. The AIDS crisis drove lasting changes in public health policy, while debt crises in developing nations reshaped the role of international financial institutions.
