The derde (derda, derdai, dardai) is the title held by the highest religious and political authority among the Toubou Teda of the Tibesti, in north-western Chad.
Oueddei Kichidemi was the father of the former Chadian President Goukouni Oueddei and was the tribal leader, or derde, of the Toubou Teda of the Tibesti during the First Chadian Civil War.
The Teda of the Tibesti in the 17th and 18th centuries distinguished themselves for their raids from the Fezzan to the north and to Borno to the south.
In May 1771, the Three battles of Sarbakusa were fought south of Teda within the modern borders of this woreda between Ras Mikael Sehul and the triumvirate of Fasil, Goshu of Amhara, and Wand Bewossen of Begemder.
