Chad

Chad is a landlocked country in north-central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the south-west, Nigeria to the southwest (at Lake Chad), and Niger to the west.
Chad has several regions: a desert zone in the north, an arid Sahelian belt in the centre and a more fertile Sudanian Savanna zone in the south. Lake Chad, after which the country is named, is the largest wetland in Chad and the second-largest in Africa. The capital N'Djamena is the largest city. Chad's official languages are Arabic and French. Chad is home to over 200 different ethnic and linguistic groups. Islam (51.8%) and Christianity (44.1%) are the main religions practiced in Chad.
