Battle of Boyacá in the context of United Provinces of New Granada

Bogotá (/ˌboʊɡəˈtɑː/, also UK: /ˌbɒɡ-/, US: /ˈboʊɡətɑː/, Spanish pronunciation: [boɣoˈta] ), officially Bogotá, Distrito Capital, abbreviated Bogotá, D.C., and formerly known as Santa Fe de Bogotá (Spanish: [ˌsanta ˈfe ðe βoɣoˈta]; lit. 'Holy Faith of Bogotá') during the Spanish Imperial period and between 1991 and 2000, is the capital and largest city of Colombia. The city is administered as the Capital District, as well as the capital of, though not politically part of, the surrounding department of Cundinamarca. Bogotá is a territorial entity of the first order, with the same administrative status as the departments of Colombia. It is the main political, economic, administrative, industrial, cultural, aeronautical, technological, scientific, medical and educational center of the country and northern South America.

Bogotá was founded as the capital of the New Kingdom of Granada on 6 August 1538 by Spanish conquistador Gonzalo Jiménez de Quesada after a harsh expedition into the Andes conquering the Muisca, the indigenous inhabitants of the Altiplano. Santafé (its name after 1540) became the seat of the government of the Spanish Royal Audiencia of the New Kingdom of Granada (created in 1550), and then after 1717 it was the capital of the Viceroyalty of New Granada. After the Battle of Boyacá on 7 August 1819, Bogotá became the capital of the independent nation of Gran Colombia. It was Simón Bolívar who rebaptized the city with the name of Bogotá, as a way of honoring the Muisca people and as an emancipation act towards the Spanish crown. Hence, since the Viceroyalty of New Granada's independence from the Spanish Empire and during the formation of present-day Colombia, Bogotá has remained the capital of this territory.

Bolívar's campaign to liberate New Granada, also known as the Liberation Campaign of 1819, was part of the Colombian and Venezuelan wars of independence and was one of the many military campaigns fought by Simón Bolívar. In 1819 Bolívar led a combined New Granadan and Venezuelan Army in a campaign to liberate New Granada which had been under Spanish control since 1816.

Bolívar marched his army through the flooded plains from Venezuela and entered the Casanare Province with his army in June 1819, combining his forces with those of Francisco de Paula Santander at Tame, Arauca, on 11 June. The combined Patriot force reached the Eastern Range of the Andes on 22 June and began a grueling crossing. On 6 July, the Patriots descended from the Andes arriving at Socha and into the valleys of central New Granada. After a brief convalescence, the Patriots fought a series of battles against the III Division of the Royalist army of Spanish colonel José María Barreiro Manjón, with the campaign culminating at the decisive Battle of Boyacá, where Bolivar's forces routed and dismantled the Royalist Army entering Santa Fe de Bogotá triumphantly 3 days later.

The British Legion (Spanish: Legión británica) or British Legions were foreign volunteer units which fought under Simón Bolívar against Spain for the independence of Colombia, Venezuela, and Ecuador, and under José de San Martín for the independence of Peru, in the Spanish American wars of independence. Venezuelans generally called them the Albion Legion. They were composed of over seven thousand volunteers, mainly Napoleonic War veterans from Great Britain and Ireland, as well as some German veterans and some locals recruited after arriving in South America. Volunteers in the British Legion were motivated by a combination of both genuine political conviction and mercenary motives.

Their greatest achievements were at the Boyacá (1819), Carabobo (1821), Pichincha (1822) and Battle of Ayacucho (1824) which secured independence for Colombia, Venezuela, Ecuador and Peru from Spanish rule respectively.
