The town of Nai Garhi which means a 'new fortress' was established by Raja Chattradhari Singh of Sengar dynasty.

[1] One of the Sengar scions was Raja Chattradhari Singh whose father being the junior prince migrated to Nai Garhi region, a few years before Mauganj was attacked by Baghelas.

According to the bardic tales, the fort was first set to be built upon a land adjacent to the temple of Astha-bhuja (a varying form of goddess Durga) but the prince saw a dream where the goddess addressed him to move to a different location to maintain the sanctity of the temple and also advised him a suitable location.

The rulers of this little but highly defensive kingdom maintained sovereign rule for a long period and used the title of Raja, however, they refrained from expanding their dominion any further due to the rising prowess of the Baghelas who established a cordial relationship with the Mughals and secured Bagelkhand by appointing numerous feudal lords.

In 1812, a group of Pindaris raided Mirzapur territory which forced the then king of Rewa, Raja Jai Singh to accede to a treaty with the British Raj.

This first Anglo-Baghela treaty (1812) brought dissatisfaction in the region mostly among the Sengar Rajputs who started aggression against the British.

A number of sepoys were killed and wounded at the behest of the Sengar Thakur whose headquarters was based in the village of Itar near Manikwar town.

Reportedly, the British also kidnapped Jagat Bahadur's eight-year-old son named Gopal Sharan Singh to get their work done.

[5] While residing in his Lal Kothi Mansion in Allahabad he build cordial relationships with great poets of his time like Maithili Sharan Gupt and Harivansh Rai Bachchan.

The Higher Secondary School in Nai Garhi is named after him and every year a poet event is organised by the government in honor of Singh.
