The 1948 Summer Olympics 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, forty years earlier. The Olympics would return again to London 64 years later in 2012, making London the first city to host the games three times, and the only such city until Paris and Los Angeles host their third games in 2024 and 2028, respectively. The 1948 Olympic Games were also the first of two summer Games held under the IOC presidency of Sigfrid Edström.
The 1976 Summer Olympics, officially known as the Games of the XXI Olympiad and commonly known as Montreal 1976, were an international multi-sport event held from July 17 to August 1, 1976, in Montreal, Quebec, Canada. Montreal was awarded the rights to the 1976 Games at the 69th IOC Session in Amsterdam on May 12, 1970, over the bids of Moscow and Los Angeles. It was the first and, so far, only Summer Olympic Games to be held in Canada. Toronto hosted the 1976 Summer Paralympics the same year as the Montreal Olympics, which still remains the only Summer Paralympics to be held in Canada. Calgary and Vancouver later hosted the Winter Olympic Games in 1988 and 2010, respectively.
The 1980 Summer Olympics, officially known as the Games of the XXII Olympiad and commonly known as Moscow 1980, were an international multi-sport event held from 19 July to 3 August 1980 in Moscow, Soviet Union, in present-day Russia. The games were the first to be staged in an Eastern Bloc country, as well as the first Olympic Games and only Summer Olympics to be held in a Slavic language-speaking country. They were also the only Summer Olympic Games to be held in a socialist state until the 2008 Summer Olympics held in China. These were the final Olympic Games under the IOC Presidency of Michael Morris, 3rd Baron Killanin before he was succeeded by Juan Antonio Samaranch, a Spaniard, shortly afterwards.

The dominion did not appear at the Games under a Rhodesian banner until 1960, when it sent a fourteen-athlete delegation as part of the Federation of Rhodesia and Nyasaland.

South Sudan competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. South Sudan had been an independent nation since 2011, but its civil war had delayed its membership with the International Olympic Committee until 2015, making 2016 its first official appearance at the Olympic Games. The country was offered three universality placements in athletics, as no South Sudanese athletes met the Olympic qualifying standards prior to the Games. Three athletes, two men and one woman, competed in three track and field events, but did not win any medals. The sole woman, Margret Rumat Hassan, was given a spot eight days prior to the start of the Games that had been allotted previously to Mangar Makur Chuot. This change was against the advice of the South Sudan Athletics Federation and was due allegedly to pressure from Samsung, for whom Hassan had appeared in an advertisement. The flagbearer for both the opening and closing ceremony was Guor Marial, a marathon runner who, then unable to represent South Sudan, had competed as an Independent Olympic Athlete in 2012. Five South Sudanese nationals also competed as members of the Refugee Olympic Team.
