Bahia is one of the 26 states of Brazil, and is located in the eastern part of the country on the Atlantic coast. It is the fourth most populous Brazilian state after São Paulo, Minas Gerais and Rio de Janeiro, and the fifth-largest in size. Bahia's capital is the city of Salvador, or more properly, São Salvador da Bahia de Todos os Santos, and is located at the junction of the Atlantic Ocean and the Bay of All Saints, officially first seen by European sailors in 1501. The name "bahia" is an archaic spelling of the Portuguese word baía, meaning "bay".
