From 1990 to 1995, a rebellion by various Tuareg groups took place in Niger and Mali, with the aim of achieving autonomy or forming their own nation-state. The insurgency occurred in a period following the regional famine of the 1980s and subsequent refugee crisis, and a time of generalised political repression and crisis in both nations. The conflict is one in a series of Tuareg-based insurgencies in the colonial and post-colonial history of these nations. In Niger, it is also referred to as the Second or Third Tuareg Rebellion, a reference to the pre-independence rebellions of Ag Mohammed Wau Teguidda Kaocen of the Aïr Mountains in 1914 (Kaocen Revolt) and the rising of Firhoun of Ikazkazan in 1911, who reappeared in Mali in 1916. In fact the nomadic Tuareg confederations have come into sporadic conflict with the sedentary communities of the region ever since they migrated from the Maghreb into the Sahel region between the 7th and 14th centuries CE. Some (but not all) Tuareg wanted an independent Tuareg nation to be formed when French colonialism ended. This, combined with dissatisfaction over the new governments, led some Tuareg in Northern Mali to rebel in 1963.
