Portugal's wars against independence guerrilla fighters in its 400-year-old African territories began in 1961 with Angola. In Mozambique, the conflict erupted in 1964 as a result of unrest and frustration amongst many indigenous Mozambican populations, who perceived foreign rule to be a form of exploitation and mistreatment, which served only to further Portuguese economic interests in the region. Many Mozambicans also resented Portugal's policies towards indigenous people, which resulted in discrimination, traditional lifestyle turning difficult for many African indigenes, and limited access to Portuguese-style education and skilled employment.
