In 1975 Mozambique attained its independence from Portugal. Independence Day is celebrated on June 25, which was the day in 1962 that the liberation movement Frelimo (Frente de Libertaçao de Moçambique) was established. Under the leadership of the Marxist-Leninist party Frelimo, Mozambique became a republic of peasants and workers. A civil war (1980-1992) followed, which took a heavy toll of 1.5 million dead and 5 million refugees. In the first half of the nineties, Mozambique had a new constitution and began a process of democratization.
