Concerted efforts. The peoples' of Angola, though tribally divided rose up in various parts of the country against Portuguese rule.

The formation of liberation movements such as the MPLA, FNLA, UNITA favoured the struggle for independence.

The assistance from the socialist block also enabled the Angolans fight a successful war of independence.

Support from African states. The then independent African states

The O.A.U and its liberation committee did what ever was possible to assist the liberation struggle in Angola.

The hit and run tactics of the guerrillas helped to weaken the Portuguese.

The Angolan terrain characterised by thick forests in the interior provided the nationalists with natural hideouts where they carried out their guerrilla activities.

The reluctance of African recruits to fight fellow Africans led to the success of the Angolan war of independence.

The aid given to refugees by the UNO and some Western countries played a part of keeping the soldiers hopeful.

The 1974 coup in Lisbon which removed Caetano from power and brought in Spinola helped the liberation fighters to succeed.

The role of MPLA. In a special way the MPLA contributed to the success of the Liberation war. It was non-tribal and was well organised.

The role of CONCP. The leaders of the MPLA, FRELIMO and PAIGC formed a common party - the CONCP and held regular meetings to share tactics , ideas and the like.

Some educational and political reforms in liberated zones also won public support for MPLA.

The Portuguese military response to African militarism only led to more determination. Hence leading to success.
