Bedouin's domain is Sahara - as in the Sahara Desert. Bedouins traditionally live a nomadic lifestyle, spreading from the Persian Gulf to the Atlantic Ocean, and from the borders of Turkey to Yemen. The word 'bedouin' comes from the Arab word 'Bedou' that means "desert dweller." Estimates say nomadic Bedouins constitute about 10% of the population of the Middle East. Traditionally, the Bedouin's home is a tent set up in the desert.
