The national anthem of Bolivia (), also known as "" ("'Bolivians, a Propitious Fate'") and originally titled the "" ("Patriotic Song"), was adopted in 1851. José Ignacio de Sanjinés, a signer of both the Bolivian Declaration of Independence and the first Bolivian Constitution, wrote the lyrics. The music was composed by an Italian, Leopoldo Benedetto Vincenti. It is a march in 4/4 time, although it is popularly sung in 12/8.
