I want to know the answer to the following question:
Until when did the Portuguese government resist decolonization of their overseas territories?
All the background I'm provided with is that "The retreat from the overseas territories and the acceptance of its independence terms by Portuguese head representatives for overseas negotiations, which would create independent states in 1975, prompted a mass exodus of Portuguese citizens from Portugal's African territories (mostly from Portuguese Angola and Mozambique).". Is that enough to answer the question?
