Mir Shakti Singh

Shakti Singh was younger brother of Maharana Pratap, in his childhood he once cut his thumb to check the sharpness of a sword, seeing the brutality, his father Udai Singh consulted with his priest who said that Shakti singh would be a bane on Mewar. He then lost all favour and love from his father. Once during hunting he fought with then prince Pratap and both brother went against each other for a duel. The result of which would have ensured that one would definitely die. The priest intervened and cut himself to stop the mad brothers. Looking at the dead body of priest the brothers calmed down. Pratap asked Shakti to leave the territory of Mewar and he obediently followed. Along with another estranged brother Sagar Singh, joined the imperial army under Akbar. His descendants are known as Shaktawat.
