History
The south holds some of Colombia's oldest monuments. Around the upper Magdalena, a culture now known by the name of the town of San Agustín raised mounds, tombs and hundreds of carved stone figures, mostly in the first millennium AD, and its work stretched into what is now Tierradentro. The Pijao of Tolima fought the Spanish for decades. The Spanish founded Ibagué in 1550 and Neiva in the 1610s, and Honda, on the Magdalena, became the colonial river port where goods for Bogotá were unloaded.
The Amazon remained Indigenous until the rubber boom of the late 19th and early 20th centuries, when rubber companies, above all the Peruvian Amazon Company of Julio César Arana, enslaved and killed thousands of Uitoto, Bora and other Indigenous people around the Putumayo; the atrocities were exposed in 1912. Leticia, founded as a Peruvian settlement in 1867, passed to Colombia by treaty in 1922, and its seizure by Peruvian civilians in 1932 led to a short war, settled in Colombia's favour in 1934.
In 1964 the army's assault on Marquetalia, a peasant settlement in southern Tolima, is seen as the founding moment of the FARC, and the guerrillas later made Caquetá and Putumayo strongholds. Around San Vicente del Caguán, in Caquetá, a demilitarised zone was ceded to the FARC during peace talks from 1998 to 2002. Coca spread through the region, bringing aerial spraying under Plan Colombia. In 1985 a lahar from the Nevado del Ruiz buried the Tolima town of Armero, killing more than 20,000 people, and in 2017 a landslide in Mocoa killed over 300.
