After the World War II, as communist and anti-colonial ideologies spread across Africa, many clandestine political movements were established in support of independence using various interpretations of Marxist revolutionary ideology. These new movements seized on anti-Portuguese and anti-colonial sentiment to advocate the complete overthrow of existing governmental structures in Portuguese Africa. These movements alleged that Portuguese policies and development plans were primarily designed by the ruling authorities for the benefit of the territories' ethnic Portuguese population at the expense of local tribal control, the development of native communities, and the majority of the indigenous population, who suffered both state-sponsored discrimination and enormous social pressure to comply with government policies largely imposed from Lisbon. Many felt they had received too little opportunity or resources to upgrade their skills and improve their economic and social situation to a degree comparable to that of the Europeans. Statistically, Portuguese Africa's white Portuguese population were indeed wealthier and more educated than the indigenous majority.
