Chad is the landlocked country in north-central Africa that shares borders with Libya, Sudan, Central African Republic, Cameroon, Nigeria, and Niger—six nations in total.
Chad's position makes it a strategic bridge between the Sahara, the Sahel, and the Central African savannas. Its borders reflect colonial-era agreements (primarily French) rather than ethnic or geographic lines, contributing to ongoing regional tensions.
Lake Chad, once one of Africa's largest lakes, sits at the convergence of Chad, Cameroon, Nigeria, and Niger—its shrinkage exacerbating resource competition in the region.
