Flag of Sergipe
The civil and state flag of the Brazilian state of Sergipe consists of four alternating green and yellow horizontal stripes with a square blue canton featuring five white five-pointed stars.The flag design came into being when José Rodrigues Bastos Coelho, a late 19th century merchant from Sergipe, needed a flag to identify the state of origin of his ships, and designed the flag, originally with only four stars to represent four estuaries in Sergipe.In 1937, under the leadership of Getúlio Vargas, all state symbols were banned under the Brazilian Constitution of 1937.In 1951, the flag was reinstated with 42 stars to represent Sergipe's 42 municipalities at the time, but this was changed the following year to the original design on 3 December 1952.[2] However the state government site also lists the Piauí as one of those represented.
