The Iqta System was a system of land revenue and administrative allocation in the medieval Islamic world, particularly in the Islamic Caliphate. Under the Iqta system, land revenue rights were granted to military officials (Iqtadars) in return for military service or administrative duties. The Iqtadars collected revenue from the assigned territories and used it to support themselves and maintain troops. This system was a way for the central Islamic government to maintain control over a vast empire while also rewarding loyal officials.

On the other hand, the Amara Nayaka System was a system in place in the Vijayanagara Empire, which was a Hindu empire in South India. The Amara Nayakas were provincial governors or local chieftains who were given control over specific regions or territories within the empire. They were responsible for maintaining law and order, collecting revenue, and providing troops to the central Vijayanagara administration. This system allowed the Vijayanagara rulers to effectively govern and control their vast empire.
