Fifth Republic Movement
Venezuela historiography recognizes four "republics," or major regime changes since the country was founded in 1811. The First Republic, known as the "Venezuelan Confederation" lasted until 1812. The Second Republic is the restored republican regime that was instituted by Simón Bolívar after his Admirable Campaign in 1813, and which lasted until 1814. The Third Republic refers to the period after 1816 in which various patriot guerrilla bands joined under Bolívar's leadership in the Llanos of Venezuela and set up an independent government. This process culminated in the Congress of Angostura, but shortly thereafter the Congress declared Venezuela to be part of a larger Gran Colombia. Gran Colombia lasted only a decade and at its dissolution Venezuela became once again the "Republic of Venezuela," which is considered the start of the Fourth Republic. In 1864 the country was then restructured into the "United States of Venezuela", before reverting once again to the name, "Republic of Venezuela" in 1953. Although both periods began with the implementation of new constitutions (the fourth and twenty-fourth constitutions, respectively), both have been deemed by Venezuelan historiography as a continuation of the Fourth Republic.
Cristóbal Mendoza
In March 1811 during the Spanish American wars of independence, the first Venezuelan constitutional congress established as the executive power a triumvirate in which three men shared executive power and rotated the presidency every week. At age 39, Mendoza became a member of the triumvirate that headed the First Republic of Venezuela and was unanimously elected by the other two as the first to go in rotation on 5 March 1811. With Manuel Moreno de Mendoza serving as the interim first president in his absence, Mendoza arrived in Caracas to begin serving his first week-long term on 25 April 1811. As part of the triumvirate, Mendoza began the war for independence against the parts of Venezuela that still supported the Spanish monarchy. He also was the author of the Venezuelan Declaration of Independence, issued on 5 July 1811. While in office he formed part of the constitutional convention that designed and promulgated the first Constitution of the Republic of Venezuela in December 1811. In March 1812, a second presidential triumvirate was appointed, with Mendoza, Juan Escalona and Baltazar Padron resigning and Fernando Toro, Francisco Javier Ustáriz and Francisco Espejo taking power.
