History
The plains and forests of the east were the land of many Indigenous peoples — the Sikuani, Achagua, Piapoco and others on the savannas, and Tukano-speaking groups, Curripaco and Puinave in the rivers of the Amazon-Orinoco divide. Rock paintings in the Serranía de la Lindosa in Guaviare are among the oldest human traces in the region. From the 17th century, Jesuit missionaries set up missions and cattle ranches in Casanare and along the Meta river, and the herds that ran wild after their expulsion in 1767 were the basis of the llanero way of life.
The plains played a decisive role in independence. Llanero horsemen formed the backbone of the patriot cavalry, and in 1819 Bolívar and Santander led their army from Casanare over the frozen Andes of Pisba to win at Boyacá. After independence, the region was governed as a distant frontier; most of its departments — Arauca, Casanare, Vichada, Guaviare, Vaupés and Guainía — were territories until the 1991 constitution made them full departments. Villavicencio, founded in the 1840s, grew as the gateway to the plains.
During La Violencia, Liberal guerrillas of the Llanos led by Guadalupe Salcedo fought the Conservative government until a 1953 amnesty. Later the FARC made the Macarena and Guaviare strongholds, the ELN grew in Arauca around the Caño Limón oil field, and paramilitaries carried out massacres such as Mapiripán in 1997. Since the 2016 accord, parts of the region have opened to visitors, but the ELN and FARC dissidents continue to fight, particularly in Arauca and Guaviare.
