A People's Calendar (aPC) is an open-source project that seeks to promote the worldwide history of working class movements and liberation struggles in the form of a searchable "On This Day" style calendar.
On this day in 1956, the People's Movement for the Liberation of Angola (MPLA) was founded in a merger between 2 smaller communist and anti-colonial parties. The MPLA was a major faction in the Angolan Civil War, which lasted until 2002.
