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.
Coins issued by most of the Rajput kings of medieval India were same in pattern i.e. included the name of the Ruler on one side and the picture of Goddess Laxmi on the other side. The text of the coins was written in Devnagiri script.
