History
The east was the heart of the Ouaddaï sultanate, founded in the 17th century by Abd al-Karim, who established Islam and a capital at Ouara. Ouaddaï grew into one of the most powerful states of the central Sahel, raiding south for slaves and ivory and sending caravans north across the Sahara to Kufra and Benghazi. In the 19th century the capital moved to Abéché, where the sultans built mosques and palaces, and Ouaddaï fought long wars with its neighbours, Darfur to the east and Baguirmi to the west.
France occupied Abéché in 1909 but met stubborn resistance, and the region was not fully subdued until after the First World War. In 1917 French forces killed a large number of religious scholars and notables in Abéché, an event still remembered as the "coupe-coupe" massacre. The colonial state invested little in the east, and in 1965 riots over taxes at Mangalmé in Guéra were followed by the armed rebellion of FROLINAT, which spread across the centre and east.
Since then the region has been shaped by events across the Sudan border. Chadian rebels have used Darfur as a base, and Sudan's conflicts have repeatedly spilled over: in the mid-2000s refugees from Darfur arrived in large numbers, and since 2023 the war in Sudan has brought a new and even larger influx.
