 In 1906, the Oubangui-Chari territory was united with the Chad colony; in 1910, it became one of the four territories of the Federation of French Equatorial Africa (AEF), along with Chad, Middle Congo, and Gabon.The next thirty years were marked by mostly small scale revolts against French rule and the development of a plantation-style economy.The largest of these revolts was the Kongo-Wara rebellion, when over 350,000 natives rebelled against the colonial administration.
