There are more than 200 ethnic groups in Chad. Those in the north and east are generally Muslim; most southerners are animists and Christians. Through their long religious and commercial relationships with Sudan and Egypt, many of the peoples in Chad's eastern and central regions have become more or less Arabized, speaking Arabic and engaging in many other Arab cultural practices as well. Chad's southern peoples took more readily to European culture during the French colonial period.
