Fiji became independent in 1970, after nearly a century as a British colony. Democratic rule was interrupted by two military coups in 1987, caused by concern over a government perceived as dominated by the Indian community (descendants of contract laborers brought to the islands by the British in the 19th century). A 1990 constitution favored native Melanesian control of Fiji, but led to heavy Indian emigration; the population loss resulted in economic difficulties, but ensured that Melanesians became the majority. Amendments enacted in 1997 made the constitution more equitable. Free and peaceful elections in 1999 resulted in a government led by an Indo-Fijian. Fiji has been a major contributor to UN peacekeeping missions in various parts of the world.
