Bolívar's campaign to liberate New Granada of 1819-1820 was part of the Colombian and Venezuelan wars of independence and was one of the many military campaigns Simón Bolívar fought in them. Bolívar's victory in New Granada (today, Colombia) secured the eventual independence of northern South America. It provided Bolívar with the economic and human resources to complete his victory over the Spanish in Venezuela and Colombia. Bolívar's attack on New Granada is considered one of the most daring in military history, compared by contemporaries and some historians to Napoleon's crossing of the Alps in 1800 and José San Martín's Crossing of the Andes in 1817.
