The local history of Tinwari begins from the time of the
Gurjara-Pratihara rulers. About two thousand years ago,
Osian was known as Upkesh Pattan (Umeshpur Patan) city, which was a
metropolis and had eight suburbs around it. Being a group of nine cities, it was also called Navteri Nagari. Among the eight suburbs, Tinwari was the main trading town. Due to the rule of Tanwar
Rajputs on this city, it later came to be known as Tanwari and Tinwari. Later, this
Jagir went into the hands of Sevad
Rajpurohits during the
Rathore rulers. In
V.S. 1272 (1215 A.D.), along with Rao Siha, his Rajguru Sevad Rajpurohit Devpaldev came to Marwar from
Kanoj and was given the
Jagir of Tinwari. Dalpat Singh Manohardasot of Tinwari laid down his life in 1657 fighting with the enemies on the banks of
Shipra River along with
Maharaja Jaswant Singh. His son
Akheraj lived in the forests with
Maharaja Ajit Singh for 22 years and bravely fought off the attacks of the enemies. Thakur Gumansingh Rajpurohit of Tinwari sacrificed his life for the defense of the motherland in 1815 by killing the Pathan commander while repulsing the attack of Mir Khan Pathan on
Mehrangarh Fort. During the princely period,
Jagirdars of this town made entrance gates on all the routes of entry into the town and put doors in them. Got reservoirs and wells constructed in all four parts of the city. == Early Administration ==
