The Second Republic of Venezuela (Spanish: Segunda República de Venezuela) is the name used to refer to the reestablished Venezuelan Republic declared by Simón Bolívar on 7 August 1813. This declaration followed the defeat of Domingo Monteverde by Bolívar during the Admirable Campaign in the west and Santiago Mariño in his campaign in the east.
In Cartagena, Bolivar penned a letter, the Cartagena Manifesto, in which he described the reasons that led to the fall of the First Republic, the current situation of Hispanic America, and his perspective on the future of the region.
Bolivar asked the New Granadian congress for his incorporation into the army, and was quickly promoted to the rank of Brigadier and assigned to a garrison. He then organized a flash campaign between Tunja and Pamplona, managing the expulsion of the royalist troops from this region. With the royalists in retreat, Bolivar once again addressed the New Granadian congress for authorization to intervene in Venezuela with an army of volunteers. In view of the actions Bolivar had executed in favor of the New Granadians, the congress granted his request and Bolivar marched into Venezuela.
It is during this period that the term "Republic of Venezuela" was officially used by Simón Bolívar's government. During the First Republic, upon which Bolívar based the legitimacy of his actions, the government referred to the Venezuelan state as either the "American Confederation of Venezuela" or the "United Provinces of Venezuela" in the Declaration of Independence (both terms are used interchangeably),[1] or as the "United States of Venezuela" (a term used interchangeably with "the Confederation") in the Constitution of 1811.[2]
Historians use the name Third Republic of Venezuela to refer to the period from about 1817 to 1819, when a rump government organized by Bolívar began functioning in the Venezuelan Llanos. The year before, various Venezuelan guerrilla forces managed to permanently establish themselves in the Llanos and captured the city of Angostura, which became their headquarters. This period culminated with the formation of the Congress of Angostura in 1819, which wrote a new constitution for Venezuela, replacing the one from 1811, which in theory, was still valid, although suspended since the collapse of the First Republic in 1812. The congress decreed the union of Venezuela with New Granada in a new republic, known as Gran Colombia, bringing an end to the Third Republic.
From 1820 to 1830, the territory of Venezuela was the Department of Venezuela within Gran Colombia. After the dissolution of Gran Colombia, Venezuela became once again the Republic of Venezuela, and, although undergoing various changes in constitutions and forms of government, it permanently maintained its independence from that moment on. This period is seen as a stable Fourth Republic of Venezuela.
