sentences:  South Africa was one of four African nations to attend FIFA's 1953 congress, at which the four demanded, and won, representation on the FIFA executive committee.Thus the four nations (South Africa, Ethiopia, Egypt and Sudan) founded the Confederation of African Football in 1956, and the South African representative, Fred Fell, sat at the first meeting as a founding member.It soon became clear however that South Africa's constitution prohibited racially mixed teams from competitive sport and so they could only send either an all-black side or an all-white side to the planned 1957 African Cup of Nations.
