The UK established a protectorate over the Solomon Islands in the 1890s. Some of the bitterest fighting of World War II occurred on this archipelago. Self-government was achieved in 1976 and independence two years later. Ethnic violence, government malfeasance, endemic crime, and a narrow economic base have undermined stability and civil society. In June 2003, then Prime Minister Sir Allan KEMAKEZA sought the assistance of Australia in reestablishing law and order; the following month, an Australian-led multinational force arrived to restore peace and disarm ethnic militias. The Regional Assistance Mission to the Solomon Islands (RAMSI) has generally been effective in restoring law and order and rebuilding government institutions.
