Before the year 1900, there was a battalion of soldiers of the then princely state of Bikaner to protect the north eastern boundary on the site of the present Sangaria town, which was then known as ‘Sangar’, and this is the origin of the town's name. In 1901-02 the Bikaner state railway line was extended from Hanumangarh to Bhatinda. At that time there were few people living close by so the railway station was called ‘Chautala Road’ after the name of the village Chautala situated in Haryana at a distance of from here. From that time onward people settled in the area. The State Government sanctioned an agricultural mandi here during the early twentieth century. The area was barren and there was no drinking water supply so water was transported by railway from Hanumangarh town and then supplied to each house.
