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).
Economy of Venezuela
After oil was discovered in Venezuela in 1922 during the Maracaibo strike, Venezuela's dictator Juan Vicente Gómez allowed American oil companies to write Venezuela's petroleum law. In 1943, Standard Oil of New Jersey accepted a new agreement in Venezuela based on the 50–50 principle, described as "a landmark event". Even more favorable terms were negotiated in 1945, after a coup brought to power a left-leaning government that included Juan Pablo Pérez Alfonso.
