Ethnic groups

The peoples of Chad carry significant ancestry from Eastern, Central, Western, and Northern Africa.

Chad has more than 200 distinct ethnic groups, which create diverse social structures. The colonial administration and independent governments have attempted to impose a national society, but for most Chadians the local or regional society remains the most important influence outside the immediate family. Nevertheless, Chad's people may be classified according to the geographical region in which they live.

In the south live sedentary people such as the Sara, the nation's main ethnic group, whose essential social unit is the lineage. In the Sahel, sedentary peoples live side by side with nomadic ones, such as the Arabs, the country's second major ethnic group. The north is inhabited by nomads, mostly Toubous.
