In April 1536, a group of 800 conquistadors led by Gonzalo Jiménez de Quesada left the Caribbean coastal city of Santa Marta on a harsh expedition into the heart of the Andes. This journey, that took one year and the lives of eighty percent of their men, led them into what was called by early chroniclers the "Muisca Confederation". After submitting the southern Muisca who lived on the Bogotá savanna in April 1537, the troops split up and Gonzalo Jiménez de Quesada, his brother Hernán Pérez de Quesada and various others set foot to the northeast, where they reached the territories of the "zaque" in August 1537. "Zaque" Quemuenchatocha was defeated by the Spanish on August 20, 1537 in his "bohío" in Hunza. What followed were several other expeditions to parts of the Muisca Confederation and the foundation of the city of Bogotá on August 6, 1538, becoming the capital of the New Kingdom of Granada, as the colonial lands of the Spanish Empire was called after the home region of the brothers De Quesada in Andalusia, Spain.
