There is a major history s behind this lake. A major battle was fought here when Maharana Pratap Singh refused to surrender himself to the Mughal Emperors in the year 1573. When the King refused and insulted Kunwar Man Singh (who sent the invitation along with the terms and condition for surrendering to the Mughal Emperor Akbar), Battle of Haldighati was fought alongside this lake.
The Maharana Raj Singh defeated the army of the Aurangzeb Emperor at the banks of the Udai Sagar Lake. Therefore, this lake is considered as the most important lake in the books of the rulers of Mewar. Tourists can enjoy the scenic beauty of the lake and will be able to view blue waters harvested from rain and the rivers at this lake. The Udai Sagar Lake is surely a must visit one if you are visiting Rajasthan.
