Chad is a vast Sahelian nation bridging North and Central Africa, shaped by desert, Lake Chad and oil revenues.
Over 200 ethnic groups meet at the crossroads of Arab-Islamic Sahelian culture in the north and Sub-Saharan traditions in the south, historically linked by trans-Saharan trade.
Oil exports dominate government revenue since the 2000s; the majority of the population relies on subsistence farming and livestock herding.
