Fijian Governor-General Penaia Ganilau is overthrown in a coup d'état led by Lieutenant colonel Sitiveni Rabuka.

Ratu Sir Penaia Kanatabatu Ganilau was a Fijian politician who served as the first President of Fiji, serving from 8 December 1987 until his death in 1993. He had previously served as Governor-General of Fiji, representing Elizabeth II, Queen of Fiji, from 12 February 1983 to 15 October 1987.

The Fijian coups d'état of 1987 resulted in the overthrow of the elected government of Fijian Prime Minister Timoci Bavadra, the deposition of Elizabeth II as Queen of Fiji, and in the declaration of a republic. The first coup d'état, in which Bavadra was deposed, took place on 14 May 1987; a second coup d'état on 25 September ended the monarchy, and was shortly followed by the proclamation of a republic on 10 October. Both military actions were led by Lieutenant Colonel Sitiveni Rabuka, then third in command of the Royal Fiji Military Forces.

Sitiveni Ligamamada Rabuka is a Fijian politician, sportsman, and former soldier who has been serving as Prime Minister of Fiji since 24 December 2022. He was the instigator of two military coups in 1987. He was democratically elected as Prime Minister of Fiji, serving from 1992 to 1999, and again in 2022, leading a three-party coalition. He also served as Chairman of the Great Council of Chiefs from 1999 to 2001, and later as Chairman of the Cakaudrove Provincial Council from 2001 to 2008.
