During the Mahabharata period in ancient India, a king named Rewat had a daughter named Rewati. The father used to call her Rewa, and founded a city "Rewa Wadi" named after her. Wadi and wada mean a neighbourhood (small and big, respectively) in Hindi and many other Indian languages. When Rewa married Balram, elder brother of Krishna, the king donated the city “Rewa-Wadi” to his daughter. In the course of time, the name Rewa-Wadi became Rewari.
