The 1948 Summer Olympics, officially the Games of the XIV Olympiad and officially branded as London 1948, were an international multi-sport event held from 29 July to 14 August 1948 in London, United Kingdom. Following a twelve-year hiatus caused by the outbreak of World War II, these were the first Summer Olympics held since the 1936 Games in Berlin. The 1940 Olympic Games had been scheduled for Tokyo and then for Helsinki, while the 1944 Olympic Games had been provisionally planned for London. This was the second time London hosted the Olympic Games, having previously hosted them in 1908, making it the second city to host the Summer Olympics twice (after Paris). The Olympics would return again to London 64 years later in 2012, making London the first city to host the games thrice, and the only such city until Paris, who hosted their third games in 2024, and Los Angeles, who will host theirs in 2028. The 1948 Olympic Games were also the first of two summer Games held under the IOC presidency of Sigfrid Edström. So far, the only Summer Olympics to be held in the 1940s as the 1940 and 1944 Summer Olympics were cancelled due to World War II
The 1948 Olympics came to be known as the "Austerity Games" due to the difficult economic climate and rationing imposed in the aftermath of World War II. No new venues were built for the games (with events taking place mainly at Wembley Stadium, also known as Empire Stadium, and the Empire Pool at Wembley Park), and athletes were housed in existing accommodation at the Wembley area instead of an Olympic Village, as were the 1936 Games and the subsequent 1952 Games in Helsinki. A record 59 nations were represented by 4,104 athletes, 3,714 men, and 390 women in 19 sport disciplines. Germany and Japan were not invited to participate in the games; the Soviet Union was invited but chose not to send any athletes, sending observers instead to prepare for the 1952 Olympics. Israel requested to participate (symbolically represented by Raya Bronstein and Frieda Berson-Lichtblau [he]) but was denied as the International Olympic Committee did not yet recognize the country, while the Olympic mandate of Palestine expired. This in turn shifted the view of the Arab countries who had intended to boycott the event and now decided to take part.
