The flag was adopted officially on 29 October 1953 based on a design in use from 1889. In the central shield, the stars symbolize the municipalities of the state, the eagle represents the productive forces, the key symbolizes the strategic position of the state in the south, the anchor refers to the ocean that bathes the state, and the date 17 November 1889 is that of the adoption of the republican regime. The branches correspond to the coffee plant and the phrygian cap also symbolizes the republican regime.
