Short answers, pulled from the story.
Russia, as the Russian Empire, first competed at the 1900 Summer Olympics in Paris. The Empire returned for the 1908 and 1912 Games before a forty-year absence that ended when the Soviet Union debuted at the 1952 Summer Olympics in Helsinki.
From 1994 to 2016, Russian athletes won 542 total Olympic medals, including 193 gold. That placed Russia second in the world during that span, behind only the United States.
Russia was suspended in 2017 due to a state-sponsored doping scandal. The ban implicated the national program itself, not just individual athletes, and led to Russian competitors appearing under alternative designations at subsequent Games.
Russia has been stripped of 48 Olympic medals due to doping violations, the most of any country in Olympic history. That total is four times the number of the runner-up and represents approximately 30 percent of all medals removed globally for doping.
Russia has hosted the Olympics twice. Moscow hosted the 1980 Summer Games, and Sochi hosted the 2014 Winter Games. The Moscow Games ran from the 19th of July to the 3rd of August; the Sochi Games ran from the 7th to the 23rd of February.
Russian athletes competed at the 2024 Summer Olympics as Individual Neutral Athletes, abbreviated as AIN. They were barred from team events and could not display the Russian flag, anthem, colors, or organizational affiliations.
