2 Summer Olympics, formally the Games of the XXX Olympiad and commonly known as London 2012, was an international multi-sport event that was held from 27 July to 12 August 2012 in London, United Kingdom. The first event, the group stage in women's football, began on 25 July at the Millennium Stadium in Cardiff, followed by the opening ceremonies on 27 July. 10,768 athletes from 204 National Olympic Committees (NOCs) participated.Following a bid headed by former Olympic champion Sebastian Coe and then-Mayor of London Ken Livingstone, London was selected as the host city on 6 July 2005 during the 117th IOC Session in Singapore, defeating bids from Moscow, New York City, Madrid, and Paris. London became the first city to host the modern Olympics three times, having previously hosted the Summer Games in 1908 and in 1948.Construction for the Games involved considerable redevelopment, with an emphasis on sustainability. The main focus was a new 200-hectare (490-acre) Olympic Park, constructed on a former industrial site at Stratford, East London. The Games also made use of venues that already existed before the bid.The Games received widespread acclaim for their organisation, with the volunteers, the British military and public enthusiasm praised particularly highly. The opening ceremony, directed by Danny Boyle, received widespread acclaim throughout the world, particular praise from the British public and a minority of widely ranging criticisms from some social media sites. During the Games, Michael Phelps became the most decorated Olympic athlete of all time, winning his 22nd medal. Saudi Arabia, Qatar, and Brunei entered female athletes for the first time, so that every currently eligible country has sent a female competitor to at least one Olympic Games. Women's boxing was included for the first time, thus the Games became the first at which every sport had female competitors. These were the final Olympic Games under the IOC presidency of Jacques Rogge.
The final medal tally was led by the United States, followed by China and host Great Britain. Several world and Olympic records were set at the games. Though there were several controversies, the 2012 games were deemed highly successful with the rising standards of competition amongst nations across the world, packed stadiums and smooth organisation. Furthermore, the focus on sporting legacy and post-games venue sustainability was seen as a blueprint for future Olympics.2016 Summer Olympics
The 2016 Summer Olympics (Portuguese: Jogos Olímpicos de Verão de 2016), officially known as the Games of the XXXI Olympiad and commonly known as Rio 2016, was an international multi-sport event that was held from 5 to 21 August 2016 in Rio de Janeiro, Brazil, with preliminary events in some sports beginning on 3 August.

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 Summer Olympic Games to take place under the International Olympic Committee (IOC) presidency of Thomas Bach. The host city Rio de Janeiro was announced at the 121st IOC Session in Copenhagen, Denmark, on 2 October 2009. Rio became the first South American city ever to host the Olympic Games. These were the first games 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, and the first since 2000 to be held in the Southern Hemisphere.The lead-up to these Games was ma
