Angolan nationalists in the then Belgian Congo founded the Union of the Peoples of Northern Angola (UPNA), an early organizational predecessor to the UPA and later the FNLA, helping establish a northern-based nationalist pole in the independence movement.
The People’s Movement for the Liberation of Angola (MPLA) was founded through the merger of nationalist groups in Luanda, creating a durable organizational core that would later lead one major wing of the armed struggle and ultimately claim state power at independence.
A labor revolt in the Baixa do Cassanje region (Malanje) erupted against colonial labor conditions; it is widely treated as an early trigger of the broader 1961 escalation into armed struggle against Portuguese rule.
Armed attacks in Luanda targeted a prison and police facilities in an effort to free political prisoners; these February attacks are commonly treated as the opening action of Angola’s armed independence struggle and part of the wider Portuguese Colonial War.
Forces led by Holden Roberto’s UPA crossed from Congo into northern Angola, attacking colonial outposts and settlements; the масштаб and brutality of the violence accelerated militarization and expanded the conflict beyond Luanda.
Jonas Savimbi and associates founded the National Union for the Total Independence of Angola (UNITA), adding a third major nationalist-military actor whose competition with the MPLA and FNLA would shape the transition to independence.
Portugal’s 25 April revolution overthrew the Estado Novo regime and rapidly shifted colonial policy, opening negotiations that moved Angola from a long counterinsurgency war toward a formal timetable for independence.
MPLA, FNLA, and UNITA leaders met in Mombasa and sought to curb inter-movement fighting while aligning positions for talks with Portugal—an effort to present a unified front that soon unraveled amid renewed rivalry.
Portugal, the MPLA, the FNLA, and UNITA signed the Alvor Agreement in Alvor, Portugal, establishing a transitional arrangement and fixing 11 November 1975 as the date for Angola’s independence—though implementation quickly collapsed into conflict.
South African forces covertly entered from Namibia, aligning with anti-MPLA forces and aiming to shape the independence outcome; the incursion internationalized the struggle and intensified the race for control of key territory before 11 November.
On the eve of independence, MPLA-aligned forces (FAPLA) with Cuban support defeated an FNLA-led assault (with Zairean and South African involvement) near Quifangondo, preventing the capture of Luanda and strengthening the MPLA’s claim to govern from the capital.
Agostinho Neto proclaimed independence in Luanda and the MPLA declared the People’s Republic of Angola, while rival declarations by UNITA and the FNLA elsewhere underscored that decolonization had merged into a civil and internationalized conflict.
