settlement at that place.

Seventy years later, and about fifty years before the Norman conquest of
England, certain Persians settled at Kilwa in East Africa, led by Ali, who
had been despised in his land because he was the son of a black Abyssinian
slave mother. Kilwa, because of this, eventually became the most important
commercial station on the East African coast, and in this and all these
settlements a very large mulatto population grew up, so that very soon the
whole settlement was indistinguishable in color from the Bantu.

In 1330 Ibn Batuta visited Kilwa. He found an abundance of ivory and some
gold and heard that the inhabitants of Kilwa had gained victories over the
Zenji or Bantu. Kilwa had at that time three hundred mosques and was
"built of handsome houses of stone and lime, and very lofty, with their
windows like those of the Christians; in the same way it has streets, and
these houses have got terraces, and the wood-work is with the masonry,
with plenty of gardens, in which there are many fruit trees and much
water."[32] Kilwa after a time captured Sofala, seizing it from Magadosho.
Eventually Kilwa became mistress of the island of Zanzibar, of Mozambique,
and of much other territory. The forty-third ruler of Kilwa after Ali was
named Abraham, and he was ruling when the Portuguese arrived. The latter
reported that these people cultivated rice and cocoa, built ships, and had
considerable commerce with Asia. All the people, of whatever color, were
Mohammedans, and the richer were clothed in gorgeous robes of silk and
velvet. They traded with the inland Bantus and met numerous tribes,
receiving gold, ivory, millet, rice, cattle, poultry, and honey.

On the islands the Asiatics were independent, but on the main lands south
of Kilwa the sheiks ruled only their own people, under the overlordship of
the Bantus, to whom they were compelled to pay large tribute each year.
