The 1984 Summer Olympics, officially known as the Games of the XXIII Olympiad, were held in Los Angeles, California, USA. The games are perhaps most known for the impressive performance of the US team, which won a total of 174 medals, including 83 gold medals. This remains the most gold medals won by a single nation at a Summer Olympics. The 1984 Olympics were also notable for being the first to be fully sponsored by private funds, without any government financing. This allowed for the construction of new facilities and infrastructure, which helped to modernize the city of Los Angeles. The 1984 Olympics were also noteworthy for the boycott by the Soviet Union and several other Eastern Bloc countries. This was in response to the US-led boycott of the 1980 Summer Olympics in Moscow, which was held in protest of the Soviet Union’s invasion of Afghanistan. As a result, many of the top athletes from these countries did not participate in the 1984 Olympics. Finally, the 1984 Olympics were memorable for a number of individual achievements, such as Carl Lewis winning four gold medals in track and field, Mary Lou Retton becoming the first American woman to win the all-around gold medal in gymnastics, and Edwin Moses winning his second gold medal in the 400m hurdles.
