Several rebel groups, most importantly FRELIMO, fought against Portugal in the Mozambican War of Independence from 1964. One insurgent faction, the Mozambique Revolutionary Committee (COREMO), was active in northwestern Mozambique. It splintered in 1968 when its deputy president Amos Sumane broke off and founded the Rumbezi African National Union (UNAR). UNAR was primarily active in Zambezia Province, a region where FRELIMO had little popular support. Sumane's forces fought for the separation of "Rumbezia", the region between the Rovuma and Zambezi rivers, from Mozambique and its eventual unification with Malawi. FRELIMO claimed that UNAR was created by the Portuguese PIDE-DGS secret police and the Malawian government under President Hastings Banda. UNAR was short-lived, but Sumane remained active and forged close links to the Mozambican community in Malawi.
