1940 Summer Olympics in the context of "1964 Summer Olympics"

The 1952 Summer Olympics (Finnish: Kesäolympialaiset 1952, Swedish: Olympiska sommarspelen 1952), officially known as the Games of the XV Olympiad (Finnish: XV olympiadin kisat, Swedish: Spel i XV Olympiaden) and commonly known as Helsinki 1952, were an international multi-sport event held from 19 July to 3 August 1952 in Helsinki, Finland.

After Japan declared in 1938 that it would be unable to host the 1940 Olympics in Tokyo due to the ongoing Second Sino-Japanese War, Helsinki had been selected to host the 1940 Summer Olympics, which were then cancelled due to World War II. Tokyo eventually hosted the games in 1964. Helsinki is the northernmost city at which a summer Olympic Games have been held. With London hosting the 1948 Olympics, 1952 is the most recent time when two consecutive summer Olympic Games were held entirely in Europe. The 1952 Summer Olympics was the last of the two consecutive Olympics to be held in Northern Europe, following the 1952 Winter Olympics in Oslo, Norway.

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.

The modern Olympics began in 1896. Since then, summer and winter games have usually celebrated a four-year period known as an Olympiad. From the inaugural Winter Games in 1924 until 1992, winter and summer Games were held in the same year. Since 1994, summer and winter Games have been held in staggered even years. The last Olympic games were held at Paris in July-Aug 2024. Through 2024, there have been 30 Summer Olympic Games, held in 23 cities, and 24 Winter Olympic Games, held in 21 cities. In addition, three summer and two winter editions of the games were scheduled to take place but were later cancelled due to war: Berlin (summer) in 1916; Sapporo–Garmisch-Partenkirchen (winter) and Tokyo–Helsinki (summer) in 1940; and Cortina d'Ampezzo (winter) and London (summer) in 1944. The 1906 Intercalated Olympics were officially sanctioned and held in Athens. However, in 1949, the International Olympic Committee (IOC) decided to unrecognize the 1906 Games. The 2020 Summer Olympics in Tokyo were postponed for the first time in the Olympics history to summer 2021 due to the COVID-19 pandemic, with the 2022 Winter Olympics being held roughly six months later in Beijing which also hosted the 2008 Summer Olympics.

Five cities and regions have been chosen by the IOC to host upcoming Olympic Games: the 2026 Winter Olympics will be the first Olympic Games officially shared between two host cities (Milan and Cortina d'Ampezzo); Los Angeles for the 2028 Summer Olympics; the 2030 Winter Olympics will be the first Olympic Games to be hosted by a region (the French Alps—comprising 7 cities and towns); Brisbane will host the 2032 Summer Olympics; and Utah will host the 2034 Winter Olympics.

The 1936 Winter Olympics, officially known as the IV Olympic Winter Games (German: IV. Olympische Winterspiele) and commonly known as Garmisch-Partenkirchen 1936, were a winter multi-sport event held from 6 to 16 February 1936 in the market town of Garmisch-Partenkirchen, Germany. Later that year, the country also hosted the 1936 Summer Olympics, which were held in Berlin. It was the last year in which the Summer and Winter Games both took place in the same country (the cancelled 1940 Olympics would have been held in Japan, with Tokyo hosting the Summer Games and Sapporo hosting the Winter Games).

The 1940 Winter Olympics, officially known as the V Olympic Winter Games (第五回オリンピック冬季競技大会, Dai Go-kai Orinpikku Tōkikyōgi Taikai) and as Sapporo 1940 (札幌1940), was a planned international multi-sport event scheduled to have been held from 3 to 12 February 1940 in Sapporo, Empire of Japan. They were ultimately cancelled because of World War II alongside the 1940 Summer Olympics in Tokyo City, Empire of Japan (later Helsinki, Finland), and were the second games to be canceled due to war.

Sapporo subsequently hosted the 1972 Winter Olympics, becoming the first city in Asia to host the Winter Olympics.
