Cape Verde People
The Cape Verde archipelago was uninhabited until the Portuguese discovered the islands in 1456. African slaves were brought to the islands to work on Portuguese plantations. As a result, Cape Verdeans are of mixed African and European origin. The influence of African culture is most pronounced on the island of Santiago, where half the population resides. Sparse rain and few natural resources historically have induced Cape Verdeans to emigrate. It is believed that of the more than 1 million individuals of Cape Verdean ancestry, less than half actually live on the islands. Some 500,000 people of Cape Verdean ancestry live in the United States, mainly in New England. Portugal, Netherlands, Italy, France, and Senegal also have large communities.

The official language is Portuguese, but most Cape Verdeans also speak a Creole dialect--Crioulo--which is based on archaic Portuguese but influenced by African and European languages. Cape Verde has a rich tradition of Crioulo literature and music.
