Spanish conquest of the Chibchan Nations refers to the conquest by the Spanish monarchy of the Chibcha language-speaking nations, mainly the Muisca and Tairona that inhabited present-day Colombia, beginning the Spanish colonization of the Americas.
The first inhabitants of Colombia were migrating members of the Mesoamericans who established themselves in the area c. 1200 BC followed by two other waves c. 500 BC and a third one between 400 and 300 BC. Later on the group of Arawak coming from southern South America made presence in the area, and a third wave of migrating groups, the warring Caribs established in the lower lands and pushed the Mesoamericans to the mountains. The southern areas of present-day Colombia were also part of the Inca Empire.
There were two main tribes that were socially and economically developed at the time of the Spanish arrival: the Muisca, and the Tairona. Both were within the Chibchan Nations.
By the 16th century, the Chibchas, were divided into two main groups: the Muisca, located in the plateaus of Cundinamarca and Boyacá, and the Tairona, who settled along the northern spur of the Sierra Nevada de Santa Marta in present-day Magdalena, Cesar and La Guajira departments.
The territory was discovered by Spanish explorer Alonso de Ojeda in 1499, though he never landed. A short time later, Juan de la Cosa, another Spanish explorer, landed on what is today called Cabo de la Vela (Cape of Sails) in the Guajira Peninsula.
In 1502, on another coast of present-day Colombia, near the Gulf of Urabá, Spanish explorers led by Vasco Núñez de Balboa explored and conquered the area near the Atrato River. There they founded Santa María la Antigua del Darién (c. 1509) and the now-vanished town of San Sebastian de Urabá (c. 1508-1510), the first two European settlements on the mainland of the Americas.
