List of participating nations at the Winter Olympic Games
The first Winter Games were held in 1924, in Chamonix, France. They were originally called "International Winter Sports Week" and held in association with the 1924 Summer Olympics, but were in retrospect designated by the International Olympic Committee (IOC) as the "I Olympic Winter Games".
Sixteen nations participated in these Games: fourteen from Europe and two from North America.
Four years later, 25 nations were represented at the 1928 Winter Olympics, in St. Moritz, Switzerland, including Argentina (the first nation from the Southern Hemisphere), Japan (the first Asian nation), and Mexico.
Participation in the 1932 Games, held in Lake Placid, United States, during the Great Depression, was reduced to 17 nations.
The 1936 Winter Games, in Garmisch-Partenkirchen, Germany, had 28 participating nations, the largest number to that date.
These would be the last Winter Games for twelve years, as the planned 1940 Games and 1944 Games were cancelled due to World War II.
List of bids for the Summer Olympics
The first three games were not subject to bids; the first IOC Session, in 1894, awarded the first games to Athens (1896) and Paris (1900), respectively. The 1904 Olympics were initially awarded to Chicago, but then moved to St. Louis to be co-located with the World Fair. A system with bids was introduced ahead of the 1908 Olympics, and were awarded to Rome. After the 1906 eruption of Mount Vesuvius, Italy returned the games to IOC, which awarded them to London. The 1916 Olympics were awarded to Berlin, but canceled due to the First World War. The 1940 Olympics were originally awarded to Tokyo, but after the 1938 break-out of the Second Sino-Japanese War, they were returned to the IOC, who awarded them to Helsinki. The games, and the 1944 Olympics awarded to London, were ultimately canceled due to the Second World War. The 1956 Olympics were awarded to Melbourne, but Australian horse quarantine rules forced the equestrian events to be held in Stockholm. Three times there have been only a single bid, Stockholm in 1912, and Los Angeles in 1932 and 1984. Starting with the 2004 Olympics, only the highest-rated cities are short-listed for the final IOC vote.
