 The Mozambique Liberation Front or FRELIMO ( <unk> de <unk> de Moçambique ) , formally ( Marxist @-@ <unk> as of 1977 but <unk> to such positions since the late 1960s ) , was formed in Dar es Salaam , the largest city in neighbouring Tanzania , on June 25 , 1962 . It was created during a conference , by political figures who had been forced into exile , by the merging of various existing nationalist groups , including the Mozambican African National Union , National African Union of Independent Mozambique and the National Democratic Union of Mozambique which had been formed two years earlier . It was only in exile that such political movements could develop , due to the strength of Portugal 's grip on <unk> activity within Mozambique itself .
