The Africa Cup of Nations, officially CAN, also referred to as African Cup of Nations, or AFCON, is the main international 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. The title holders at the time of a FIFA Confederations Cup qualify for that competition. As of 2013, the tournament was switched to being held in odd-numbered years so as not to clash with the FIFA World Cup.
