On April 6, 1973, the President François Tombalbaye changed its name to N’Djamena (taken from the Arabic name of a nearby village, ''Niǧāmīnā'', meaning "place of rest") as part of his ''authenticité'' program of Africanization. The city was occupied by Libya during the 1980–81 Libyan intervention as part of the Chadian–Libyan conflict, and the associated Transitional Government of National Unity.
