Several communist countries supported the guerrillas with weapons and military training. The conflict in Portuguese Guinea involving the PAIGC guerrillas and the Portuguese Army was the most intense and damaging of all Portuguese Colonial War. Thus, during the 1960s and early 1970s, Portuguese development plans promoting strong economic growth and effective socioeconomic policies, like those applied by the Portuguese in the other two theaters of war (Portuguese Angola and Portuguese Mozambique), were not possible. In 1972 Cabral sets up a government in exile in Conakry, the capital of neighbouring Guinea. It was there, in 1973, that he was assassinated outside his house - just a year before a left-wing military coup in Portugal dramatically altered the political situation.
