How did the Inca expand their territory and become a powerful empire?

The Inca expanded their territory through a combination of military conquest, strategic alliances, and diplomacy. They employed a well-organized army to subdue neighboring tribes and incorporated them into their empire, often allowing local leaders to retain some authority. Additionally, the Incas built extensive road networks, facilitating communication and troop movement, which helped maintain control over their vast territory. Their effective administration and the integration of conquered peoples into their culture further solidified their power.
