Even though the Sahara is so vast, few people live there. The only densely settled part is Egypt's Nile Valley. The inhabitants of the rest of the Sahara are mostly Arab and Berber tribesmen. Some live on oases; others are nomads, who wander from one oasis to the next with their camels and goats. The best-known nomads are the Tuaregs, a Berber group who have controlled the caravan routes for years. Islam is the chief religion.
Although large areas of the desert are empty, well watered oases can support several thousand people. Dates are the most important crop, but cereal grains, fruits, and vegetables also are grown where there is enough water to support additional crops. Wandering herdsmen stop at the oases for food and drink. Camel caravans deliver news, exchange goods, and carry export date crops to port cities.
