The agreement was signed by the Portuguese government, the People's Movement for the Liberation of Angola (MPLA), the National Liberation Front of Angola (FNLA), National Union for the Total Independence of Angola (UNITA), and it established a transitional government composed of representatives of those four parties. It was not signed by the Front for the Liberation of the Enclave of Cabinda (FLEC) or the Eastern Revolt as the other parties excluded them from negotiations. The transitional government soon fell apart, with each of the nationalist factions, distrustful of the others and unwilling to share power, attempting to take control of the country by force.
