Olympic Games: The Games of the XIV Olympiad: After a hiatus of 12 years caused by World War II, the first Summer Olympics to be held since the 1936 Summer Olympics in Berlin, open in London.

The modern Olympic Games are the world's preeminent international sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games, open to both amateur and professional athletes, involves more than 200 teams, each team representing a sovereign state or territory. By default, the Games generally substitute for any world championships during the year in which they take place. The Olympics are staged every four years. Since 1994, they have alternated between the Summer and Winter Olympics every two years during the four-year Olympiad.

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 summer olympics twice. 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.

The Summer Olympic Games, also known as the Summer Olympics or the Games of the Olympiad, is a major international multi-sport event normally held once every four years. The inaugural Games took place in 1896 in Athens, then part of the Kingdom of Greece, and the most recent was held in 2024 in Paris, France. This was the first international multi-sport event of its kind, organised by the International Olympic Committee (IOC) founded by Pierre de Coubertin. The tradition of awarding medals began in 1904; in each Olympic event, gold medals are awarded for first place, silver medals for second place, and bronze medals for third place. The Winter Olympic Games were created out of the success of the Summer Olympic Games, which are regarded as the largest and most prestigious multi-sport international event in the world.
