The flag of Piaui was created on 24 July 1922. The blue canton and a star represents the state itself and the green and yellow bars represent Piauí's union with Brazil. In 2005 the words "13 DE MARÇO DE 1823" were added below the star to commemorate the date of the Battle of Jenipapo, an engagement in Brazil's war of independence.
Most mass-produced flags are commonly 150x90cm / 5x3' or 90x60cm / 3x2', which will often vary from the official size ratio. We now offer a custom-manufactured official size option for our many of our flags.
