Wadai Empire (1635–1912)
The Wadai Empire or Sultanate was a kingdom located to the east of Lake Chad in present-day Chad and in the Central African Republic. The sultanate expanded its power as it profited considerably from its strategic position astride the trans-Saharan trade routes. The militaristic Wadai fought French domination until being overcome on June 6, 1909. Resistance continued until 1912.
