MOMBAZA, a country of Africa in Zangebar, subject to the Portuguese, from whence they export slaves, gold, ivory, rice, flesh, and other provisions, with which they supply the settlements in Brasil. The king of this country being a Christian, had a quarrel with the Portuguese governor, took the castle by assault in 1631, turned Mahometan, and murdered all the Christians; but in 1729 they became masters of the territory again.
