1980 Moscow Olympics Boycott

The 1980 Moscow Olympics were devastated by the largest boycott in Olympic history, with 65 countries—led by the United States—refusing to participate over the Soviet Union’s 1979 invasion of Afghanistan. Only 80 nations competed, the lowest turnout since 1956, and 36 gold medals went uncontested due to absent rivals. This political standoff cost athletes their dreams: U.S. swimmer Tracy Caulkins, who set five world records, never competed, while Soviet gymnast Alexander Dityatin won 8 medals without full competition. The boycott reduced total viewership to roughly 2.5 billion, compared to 3.5 billion for the 1976 Montreal Games, and cost the Soviet Union an estimated $9 billion in preparation.
