Fiji has suffered several coups d'état: military in 1987 and 2006 and civilian in 2000. All were ultimately due to ethnic tension between indigenous Fijians and Indo-Fijians, who originally came to the islands as indentured labour in the late nineteenth and early twentieth century. The 1987 coup followed the election of a multi-ethnic coalition, which Lieutenant Colonel Sitiveni Rabuka overthrew, claiming racial discrimination against ethnic Fijians. The coup was denounced by the United Nations and Fiji was expelled from the Commonwealth of Nations.
