Pate Island in the context of "Coast Province"

The Swahili coast (Swahili: Pwani ya Waswahili) is a coastal area of East Africa, bordered by the Indian Ocean and inhabited by the Swahili people. It includes Sofala (located in Mozambique); Mombasa, Gede, Pate Island, Lamu, and Malindi (in Kenya); and Dar es Salaam 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 Sultanate of the Geledi (Somali: Saldanadda Geledi, Arabic: سلطنة غلدي) also known as the Gobroon dynasty, was a Somali kingdom that ruled parts of the Horn of Africa during the late-17th century to the early 20th century. The Sultanate was governed by the Gobroon dynasty. It was established by the Geledi soldier Ibrahim Adeer, who had defeated various vassals of the Ajuran Sultanate and elevated the Gobroon to wield significant political power. Following Mahamud Ibrahim's consolidation, the dynasty reached its apex under Yusuf Mahamud Ibrahim, who successfully modernized the Geledi economy and eliminated regional threats with the Conquest of Bardera in 1843, and would go on to receive tribute from Said bin Sultan, the ruler of the Omani Empire. Geledi Sultans had strong regional ties and built alliances with the Pate and Witu Sultanates on the Swahili coast. Trade and Geledi power would continue to remain strong until the death of the well known Sultan Ahmed Yusuf in 1878. The sultanate was eventually incorporated into Italian Somaliland in 1911.
