Venezuelan War of Independence
The establishment of the Supreme Caracas Junta following the forced deposition of Vicente Emparan as Captain General of the Captaincy General of Venezuela on April 19, 1810, marked the beginnings of the war. On July 5, 1811, seven of the ten provinces of the Captaincy General of Venezuela declared their independence in the Venezuelan Declaration of Independence. The First Republic of Venezuela was lost in 1812 following the 1812 Caracas earthquake and the Battle of La Victoria (1812). Simón Bolívar led an "Admirable Campaign" to retake Venezuela, establishing the Second Republic of Venezuela in 1813; but this too did not last, falling to a combination of a local uprising and Spanish royalist reconquest. Only as part of Bolívar's campaign to liberate New Granada in 1819-20 did Venezuela achieve a lasting independence from Spain (initially as part of Gran Colombia).
Francisco de Miranda
Miranda gathered around him a group of similarly minded individuals and helped establish an association, "la Sociedad Patriotica", modeled on the political clubs of the French Revolution. By the end of the year, the Venezuelan provinces elected a congress to deal with the future of the country, and Miranda was chosen as the delegate from El Pao, Barcelona Province. On July 5, 1811, it formally declared Venezuelan independence and established a republic. The congress also adopted his "tricolor" as the Republic's flag.
