The modern Colombian Army has its roots in the Army of the Commoners (), which was formed on 7 August 1819 – before the establishment of the present day Colombia – to meet the demands of the Revolutionary War against the Spanish Empire. After their triumph against the Spanish, the Army of the Commoners disbanded, and the Congress of Angostura created the Gran Colombian Army to replace it. Throughout its history, the Colombian Army has seen action in several wars and civil conflicts, including the Gran Colombia-Peru War, the Ecuadorian–Colombian War, the Thousand Days War, and the Korean War. Since the mid-1960s, the Colombian Army has been involved in a low-intensity asymmetrical war known as the Colombian Armed Conflict.
