The Sapa Inca was the emperor of the Inca Empire, a powerful civilization that thrived in South America during the 15th and 16th centuries. As the supreme ruler, the Sapa Inca held absolute power over the empire, which stretched across modern-day Peru, Ecuador, and parts of Bolivia and Chile. The title signifies not only political authority but also a divine connection to the sun god, Inti. The Sapa Inca was responsible for the administration of the empire, overseeing vast territories and diverse cultures. This role included managing resources, leading military campaigns, and ensuring the construction of impressive infrastructure, such as the famous Inca Road system and the citadel of Machu Picchu.
