Rana Sihra was a Naru Rajput ruler. He was descendant from Raja Nipal Chand of the fifth generation.
Mahmud of Ghazni (971-1030) conquered the country on both sides of the Sutlej, and placed Talochar in charge of it. After leaving Mau he made Bajwara his capital, but the attacks made on him by the hill chiefs compelled him to invoke Mahmud's aid, and Pathan troops were sent to him who were cantoned along the foot of the Siwaliks and are still settled there. Rana Sihra, Naru Khan's descendant in the fifth generation, returned to Ajudhia, whence Talochar had come, and re-conquered his ancient kingdom, over which he appointed a viceroy. He died on his way back to Punjab at Sunam. His third descendant, Rana Mal, had five sons: Kilcha, Bhoja, Dhuni, Massa and Jassa, who divided the territory. Kilcha got the Hariana Ilaqa with 750 villages, including Nandachuar, Bahram, Bulhowal, with the title of Tika. Bhoja got Bajwara, Sham Chaurasi, Ahrana, Ajram, Baroti and their dependent villages. Dhuni got the Dhuniat.
