Rio Grande do Sul's first official symbol was its flag, which was established by Title VI of the state constitution adopted on 14 July 1891.[1][2] This Title specified the tricolor of the Riograndense Republic as the state flag and was the only piece of legislation to mention the state flag until 1966 when two more state symbols, the state coat of arms and state song, were adopted.[1] Fifteen additional symbols have been added since 1980, with thirteen of which being added after 2000. The newest symbol of Rio Grande do Sul is the Hino da Legalidade, which was declared the democratic resistance hymn in 2021.
