Angola Liberation Day is commemorated every February 4 in Angola, alongside the Day of the Armed Struggle. This day celebrates the actions of the People's Movement for the Liberation of Angola (M.P.L.A.), which involved a significant attack to liberate detained independence leaders from a jail in Luanda. The origins of this observance trace back to February 1961, when black militants initiated a rebellion against Portuguese colonial rule, marked by assaults on police and military establishments. The Angolan War of Independence, part of the broader Portuguese Colonial War, continued until a ceasefire was declared in 1974, leading to Angola's eventual independence. Typical customs associated with the day include remembrance of the struggle for independence and recognition of the sacrifices made by those involved in the liberation efforts.
