In 1899, the Apure and Guayana States were separated and established their autonomy; and it is from the 1901 Constitution that the name of Guayana State is changed to Bolivar State, as a tribute to the Liberator Simon Bolivar, who established in the city of Angostura, today's Bolivar City, the bases of the action that allowed him to liberate the current Bolivarian nations (Venezuela, Colombia, Panama, Ecuador, Peru and Bolivia).
