The 1960s in Angola were marked by the War of Independence (1961–1975). Portuguese police arrested Agostinho Neto of the MPLA and future President of Angola (1975–1979) in 1960 for the third time. Delegates discussed Cabinda's self-determination in relation to Angola at the 4th Commission of the United Nations on Decolonization in New York in 1962. Cabinda became a member of the Organisation of African Unity (OAU) as the 39th colonized country in 1964.
