The state of Bahia derives its name from the Portuguese word for "bay" (bahia or baía).1
When Portuguese explorers first entered the region in 1501, they arrived at the large, deep natural harbor where the city of Salvador is now located. Because they discovered this body of water on All Saints’ Day, November 1, they named it Todos os Santos Bay (All Saints Bay). The surrounding area subsequently became known simply as "Bahia," a name that was eventually adopted for the state itself.12
