The answer is "True".

The Inca Empire which is also known as the Incan Empire or the Inka Empire, was the biggest realm in pre-Columbian America, and perhaps the biggest realm on the planet in the mid sixteenth century. The authoritative, political and military focal point of the realm was situated in Cusco in modern-day Peru. The Incas emerged from the highlands of Peru at some point in the mid thirteenth century.
