Kotharia is a town in Rajsamand district of Rajasthan, which was the headquarters of the former 1st class jagir (estate) of the House of Kotharia, part of the Udaipur (Mewar) state, which was in Mewar Residency in Rajputana Agency.

The first ruler of Kotharia were the descendants of the last Chauhan king of Ranthambhor, Raja Hamir Singh, about 1302.

Whose descendants settled in Mainpuri in uttar pradesh state of present-day India.

During the Battle of Khanwa, when Mughal Emperor Babur fought Maharana Sangram Singh (Rana Sanga) on 17 March 1527, one of them was Manik Chand Chauhan,[1] a chieftain from the village Rajor in present Mainpuri district, Uttar Pradesh, who joined Rana Sanga with his 4,000 men and fought to the death.

After the war, he was posthumously rewarded with the jagir of Kotharia and the title of ‘Rawat’.
