The Africa Cup of Nations referred to as AFCON (, sometimes referred to as CAN, or TotalEnergies Africa Cup of Nations for sponsorship reasons), and sometimes as African Cup of Nations, is the main international men's association football competition in Africa. It is sanctioned by the Confederation of African Football (CAF), and was first held in 1957. Since 1968, it has been held every two years, switching to odd-numbered years in 2013. In the first tournament in 1957, there were only three participating nations: Egypt, Sudan, and Ethiopia. South Africa was originally scheduled to join, but was disqualified due to the apartheid policies of the government then in power. Since then, the tournament has expanded greatly, making it necessary to hold a qualifying tournament. The number of participants in the final tournament reached 16 in 1998 (16 teams were to compete in 1996, but Nigeria withdrew, reducing the field to 15, and the same happened with Togo's withdrawal in 2010), and until 2017, the format had been unchanged, with the 16 teams being drawn into four groups of four teams each, with the top two teams of each group advancing to a "knock-out" stage. On 20 July 2017, the Africa Cup of Nations was moved from January to June and expanded from 16 to 24 teams. Egypt is the most successful nation in the cup's history, winning the tournament seven times. Three trophies have been awarded during the tournament's history, with Ghana, and Cameroon winning the first two versions to keep after each of them won a tournament three times. The current trophy was first awarded in 2002. Egypt won an unprecedented three consecutive titles in 2006, 2008, and 2010. In 2013, the tournament format was switched to being held in odd-numbered years so as not to interfere with the FIFA World Cup. Senegal are the tournament's current champions, having beaten Egypt on penalties in the 2021 final. History 1950s–60s: Origin and early years The origin of the African Nations Cup dates from June 1956, when the creation of the Confederation of African Football was proposed during the third FIFA congress in Lisbon. There were immediate plans for a continental tournament to be held and, in February 1957, the first Africa Cup of Nations was held in Khartoum, Sudan. There was no qualification for this tournament, the field being made up of the four founding nations of CAF (Egypt, Sudan,
