The Bhatner fort is located at HanumanGarh in Rajasthan, about 419 km northwest of Jaipur along the old Multan-Delhi route and 230 km north-east of Bikaner. The old name of Hanuman Garh was Bhatner, which means “FORTRESS OF BHATIS” It is believed to be 1700 years old and ranks as one of the oldest forts.
The ancient fort stands on the bank of River Ghaggar. It was built in 253 CE by Bhupat, son of Bhati king of Jaisalmer. After losing a war, King Bhupat took shelter in the jungle around the Ghaggar River. There he constructed a safe haven for himself which came to be known as Bhatner. The entire fort is built of bricks, covering an area of 52 bighas. It is in the shape of a parallelogram, with a dozen bastions on each side. Painted Grey Ware (circa 1100-800 BCE) and Rang-Mahal Ware (1st-3rd century CE) have been found in wells situated along the wall
In the middle of the thirteenth century CE, Sher Shah Suri (Sher Khan), a cousin or nephew of Balban (the Sultan of Delhi), was governor in these parts of the country.
He is said to have carried out repairs to the forts of Bhatinda and Bhatner.
In 1391, Bhatner was wrested by Timur by defeating Bhatti King Rao Doolchand. A mention has been made in “Tuzuk-e-Timuri” (Autobiography of Timur) about this fort and he stated this fort one of the strongest and secured fort of India. Even Mughal Emperor Akbar described his fortification in his book “Ain-I-Akbari”. Subsequently, the fort appears to have been held by Bhatis, Johiyas and Chayals until 1527 when it was taken by Rao Jet Singh of Bikaner.
After that, it came twice under Mughal control as well, in addition to being in possession of the royal families of Chayal and Bikaner.
Researchers believe that famous Tarain war fought between Mohammad Gouri and Prithviraj Chauhan is in the present Talwara Jheel area of the district.
This fort stands in the path of invasion of India from Central Asia and had acted as a strong barricade against the attack of enemies. Finally in the year of 1805, it was captured by Emperor Soorat Singh of Bikaner and remained with it till the formation of Rajasthan. Since the day of victory was Tuesday (known as day of Hindu God Hanuman), so he named Bhatner as Hanumangarh.
