The Swahili coast ( Pwani ya Waswahili, in Swahili) is a coastal area of the Indian Ocean in East Africa inhabited by the Swahili people. It includes Dar es Salaam; Sofala (located in Mozambique); Mombasa, Gede, Pate Island, Lamu, and Malindi (in Kenya); and Kilwa (in Tanzania). In addition, several coastal islands are included in the Swahili coast such as Zanzibar and Comoros.
Areas of what is today considered the Swahili coast were historically known as Azania or Zingion in the Greco-Roman era, and as Zanj or Zinj in Middle Eastern, Indian, and Chinese literature from the 7th to the 14th century. The word "Swahili" means people of the coasts in Arabic and is derived from the word sawahil ("coasts").
The Swahili people and their culture formed from a distinct mix of African and Arab origins. The Swahilis were traders and merchants and readily absorbed influences from other cultures. Historical documents including the Periplus of the Erythraean Sea and works by Ibn Battuta describe the society, culture, and economy of the Swahili coast at various points in its history. The Swahili coast has a distinct culture, demography, religion, and geography, and as a resultalong with other factors, including economichas witnessed rising secessionism.
In the pre-Swahili period, the region was occupied by smaller societies whose main socioeconomic activities were pastoralism, fishing, and mixed farming. Early on, those living on the Swahili coast prospered because of agriculture helped by regular yearly rainfall and animal husbandry. The shallow coast was important as it provided seafood. Starting in the early 1st millennium CE, trade was crucial. Submerged river estuaries created natural harbors as well as the yearly monsoon winds helped trade. Later in the 1st millennium there was a huge migration of Bantu people. The communities settling along the coast shared archaeological and linguistic features with those from the interior of the continent.
