The Swahili people are a Bantu ethnic group and culture found in East Africa, mainly in the coastal regions and the islands of Kenya, Tanzania and northern Mozambique. The name Swahili is derived from the Arabic word Sawahil, meaning 'coastal dwellers', and they speak the Swahili language. The Swahili are original Bantu inhabitants on the coast of East Africa, in Kenya, Tanzania and Mozambique. They are mainly united by culture and under the mother tongue of Kiswahili, a Bantu language. This also extends to Arab, Persian, and other migrants who reached the coast some believe as early as the 7th-8th c. CE, and mixed with the local people there, providing considerable cultural infusion and numerous loan words from Arabic and Persian.
