The 1980 Moscow Olympics were held in Moscow, Soviet Union, from July 19 to August 3. This event marked the 22nd modern Olympic Games and featured athletes from 80 countries competing in 21 sports. However, the games were significantly affected by a boycott led by the United States, protesting the Soviet invasion of Afghanistan in 1979. As a result, many countries, including the U.S., withdrew their athletes, leading to a reduced number of participants and events compared to previous Olympics.
