Santiago is the largest island of Cape Verde, its most important agricultural centre and home to half the nation's population. Part of the Sotavento Islands, it lies between the islands of Maio and Fogo. It was the first of the islands to be settled: the town of Ribeira Grande was founded in 1462. Santiago is home to the nation's capital city of Praia.

Cape Verde or Cabo Verde, officially the Republic of Cabo Verde, is an archipelago and island country of West Africa in the central Atlantic Ocean, consisting of ten volcanic islands with a combined land area of about 4,033 square kilometres (1,557 sq mi). These islands lie between 600 and 850 kilometres west of Cap-Vert, the westernmost point of continental Africa. The Cape Verde islands form part of the Macaronesia ecoregion, along with the Azores, the Canary Islands, Madeira and the Savage Isles.
