The 2016 Summer Olympics (), officially the Games of the XXXI Olympiad () and also known as Rio 2016, was an international multi-sport event held from 5 to 21 August 2016 in Rio de Janeiro, Brazil, with preliminary events in some sports beginning on 3 August. Rio de Janeiro was announced as the host city at the 121st IOC Session in Copenhagen, Denmark, on 2 October 2009.
11,238 athletes from 207 nations took part in the 2016 Games, including first-time entrants Kosovo, South Sudan, and the Refugee Olympic Team. With 306 sets of medals, the Games featured 28 Olympic sports, including rugby sevens and golf, which were added to the Olympic program in 2009. These sporting events took place at 33 venues in the host city and at five separate venues in the Brazilian cities of São Paulo, Belo Horizonte, Salvador, Brasília, and Manaus.
These were the first Olympic Games to be held in South America, as well as the first to be held in a Portuguese-speaking country, the first summer edition to be held entirely in the host country's winter season, the first since 1968 to be held in Latin America (the second being 2018 Summer Youth Olympics in Buenos Aires, Argentina), and the first since 2000 to be held in the Southern Hemisphere. These were also the first Summer Olympics to take place under the International Olympic Committee (IOC) presidency of Thomas Bach.
The United States topped the medal table, winning the most gold medals (46) and the highest number of medals overall (121); the US team also won its 1,000th Summer Olympic gold medal overall. Great Britain finished second and became the first country to increase its tally of medals in the Olympiad immediately after being host nation in 2012. China finished third in the medal table. Host nation Brazil won seven gold medals and 19 medals, its best result at any Olympics, finishing in thirteenth place. Bahrain, Fiji, Ivory Coast, Jordan, Kosovo, Puerto Rico, Singapore, Tajikistan and Vietnam all won their first gold medals, as did the group of Independent Olympic Athletes (from Kuwait).
Bidding process
The bidding process for the 2016 Summer Olympics was officially launched on 16 May 2007. The first step for each city was to submit an initial application to the International Olympic Committee by 13 September 2007, confirming their intention to bid. Completed official bid files containing answers to a 25-question IOC form were to be submitted by each city by the deadline of 14 January 2008. On 4 June 2008, two months before the Beijing Olympics, four candidate cities were chosen for the shortlist: Chicago, Madrid, Rio de Janeiro, and Tokyo, which had already hosted the Summer Olympics in 1964. Three cities—Baku, Doha, and Prague—failed to reach the candidature phase. Doha was not promoted, despite scoring higher than the selected candidate city Rio de Janeiro, because of their proposal to host the Olympics in October, outside the IOC's sporting calendar, added with its problems while hosting the 2006 Asian Games, including deaths and illnesses involving athletes and volunteers. Others included lack of infrastructures, including beds for athletes and media reporters at that time.
Nawal El Moutawakel of Morocco headed the 10-member Evaluation Commission, having also chaired the evaluation commission for the 2012 Summer Olympics bids, which was awarded to London, United Kingdom. The commission made on-site inspections in the second quarter of 2009. They issued a comprehensive technical appraisal for IOC members on 2 September, one month before the elections.
Many safeguards were put in place to prevent bidding cities from communicating with or directly influencing the 115 IOC members eligible to vote in the elections. For example, cities could not invite any IOC member to visit, nor could they send anything that could be construed as a gift. Nonetheless, bidding cities invested large sums in their PR and media programs to indirectly influence the IOC members by garnering domestic support and backing from sports media and general international media.
The final voting was held in Copenhagen on 2 October 2009, with Madrid and Rio de Janeiro considered favorites to secure the Games. Chicago was eliminated after the first round of voting, and Tokyo after the second (The latter city would eventually awarded the 2020 Summer Olympics in 2013). Rio de Janeiro took a significant lead over Madrid, heading into the final round; the lead was held, and Rio de Janeiro was announced as host of the 2016 Summer Olympics.
