Under the rule of the Vijayanagar empire, irrigation became prominent. The development of irrigation took place mainly during the rule of Deva Raya I. New tanks were built and dams were constructed across the river Tungabhadra.
The administrative system during the rule of the Bahamani kingdom was well-organized. Alauddin I divided the kingdom into four divisions called tarafs each entrusted under the command of an officer called tarafdar.
