from Spain sprang up around 1810, following the independence of St. Domingue (present-day Haiti) in 1804, which provided a non-negligible degree of support to the eventual leaders of this rebellion: Simón Bolívar and Francisco de Paula Santander.
A movement initiated by Antonio Nariño, who opposed Spanish centralism and led the opposition against the viceroyalty, led to the independence of Cartagena in November 1811, and the formation of two independent governments which fought a civil war – a period known as La Patria Boba. The following year Nariño proclaimed the United Provinces of New Granada, headed by Camilo Torres Tenorio. Despite the successes of the rebellion, the emergence of two distinct ideological currents among the liberators (federalism and centralism) gave rise to an internal clash which contributed to the reconquest of territory by the Spanish. The viceroyalty was restored under the command of Juan de Samano, whose regime punished those who participated in the uprisings. The retribution stoked renewed rebellion, which, combined with a weakened Spain, made possible a successful rebellion led by the Venezuelan-born Simón Bolívar, who finally proclaimed independence in 1819. The pro-Spanish resistance was finally defeated in 1822 in the present territory of Colombia and in 1823 in Venezuela.
The territory of the Viceroyalty of New Granada became the Republic of Colombia organized as a union of Ecuador, Colombia and Venezuela (Panama was then an integral part of Colombia). The Congress of Cucuta in 1821 adopted a constitution for the new Republic. Simón Bolívar became the first President of Colombia, and Francisco de Paula Santander was made Vice President. However, the new republic was very unstable and ended with the rupture of Venezuela in 1829, followed by Ecuador in 1830.
