History Before the Spanish conquest of the Eastern Colombian Andes, the region of Muzo was inhabited by the people with the same name. They extracted emeralds in pre-Columbian times, giving them the name "The Emerald People". Using poles of hard tropical wood and water, the people peeled the emeralds from the formations, in particular the Muzo Formation, named after the municipality. Historians have estimated the Muzo settled in the area of Muzo around 1000 AD. The Cariban-speaking Muzo, like their Chibcha neighbours, adored the Sun and Moon as deities. Unlike their eastern neighbours, they did not construct temples. Spanish conquest After the successful conquest by the Spanish of the eastern neighbours, the Muisca, and partial submittal of the Panche, the southern neighbours of the Muzo, the Spanish, in search of valuable resources, sent various conquistadors into the territories inhabited by the Muzo. The first to arrive in Muzo territory was Luis Lanchero, soldier of the conquest expedition led by Nikolaus Federmann, in 1539. He encountered fierce resistance by the indigenous Muzo and had to return to the newly founded capital Santafe de Bogotá of the New Kingdom of Granada in 1541. The Muzo used the rugged terrain to their advantage and attacked the forty conquistadors, whose horses had problems crossing the hills of Muzo, using poisoned arrows. During a second invasion by the Spanish into the Muzo lands, in 1544, conquistador Diego Martínez discovered the rich emerald deposits
