Ever since Portugal handed over sovereignty of its former overseas province of Angola to the local independence groups (MPLA, UNITA and FNLA), the territory of Cabinda has been a focus of separatist guerrilla actions opposing the Government of Angola (which has employed its armed forces, the FAA—Forças Armadas Angolanas) and Cabindan separatists. The Front for the Liberation of the Enclave of Cabinda-Armed Forces of Cabinda (FLEC-FAC) announced the virtual Federal Republic of Cabinda under the Presidency of N'Zita Henriques Tiago. One of the characteristics of the Cabindan independence movement is its constant fragmentation, into smaller and smaller factions.
