The coming of Arabs with Islam at the E. African coast had a great impact on people’s lives, and re-defined the lives of the people of E.Africa. Among their impacts, the following were outstanding.

With the coming of Islam, there was tremendous development and growth of Coastal city towns into city-states e.g. Mombasa, Malindi, Kilwa, Pemba, Sofala  etc.

Through their preaching, the Islamic commercial ethics were introduced i.e use of weights and measurements, not charging ribah etc.  Many expensive trade items were brought at the coast and Arabs established themselves as middlemen at the same time Africans also benefited a lot from this trade.
  • Emergency   of Islam and its spread as a way of life.   It is noted that the introduction of Islam at the coast replaced the primitive religious life of the people at the coast e.g. Some beliefs and culture were accepted and modified e.g. circumfusion for men, polygamy etc while others were abolished like child sacrifice, superstition, idol worshiping etc yet some new beliefs and practices were introduce e.g. the making of ablution thereby promoting hygiene in the society.
