The flag was adopted on December 3, 1957. It is based on a design by Luis de Camara Cascudo. In the middle of the flag is the coat of arms of the state. The coat of arms was adopted on July 1, 1909. It shows a sailboat at the coast in the middle. This is for the fishing and salt industries. Above this is a bar which shows two flowers on the sides and two cotton bolls in the center. To the sides of the shield are a coconut palm to the right and a carnauba palm to the left. The two palms are connected by two branches of sugarcane.
