Ajan, an extensive tract on the E. coast of Africa. It extends from Zanguebar to Cape Guardafui, about 10 degrees of latitude, the southern extremity being near the equator. The S. coast is sandy and barren; the X. is high, especially at Cape d'Orfui (Ras Hafoon), which is a bluff toward the sea, backed by lofty mountains of singular shape. The inhabitants belong to the Eesah or Somauli tribe. There is no river of importance. Ajan was known to the ancients, and called Azania. The inhabitants traded with the Arabs in ivory, tortoise shell, etc, and were under Arab control; and Rhaptum, the capital, was the furthest point to the south known to the Greeks.
