Dildarnagar Kamsar, also Known as Kamsar-O-Bar, is a large fertile region located on the banks of Ganges and Karamnasa. Its original name is Kamsar which is derived from Kamesaradih where its founder Narhar Khan use to live in his small fort but later Bar(Bara) was added in it. Its history dates back to the time of a Mughal emperor Babur in the year 1530. When two rulers named Raja Kam Dev and Raja Dham Dev 's family came with their army to settle here. They were the rulers of present-day Gwalior, Morena, Shivpuri and Jhansi and later the ruler of Fatehpur (then part of Kanpur), during Babur.They came here after their defeat in the Battle of Madarpur with Babur. They first settled on a place near Gahmar and then the elder brothers (Kam Dev or Rao Dalpat's) family shifted to a place named Dalpatpur now known as Reotipur. From there the family scattered all over Zamania and nearby area and establishing more than a hundred villages in Ghazipur, Buxar and present-day Kaimur districts. While Dham Dev's family established Gahmar, Chausa, Bhabua, Chainpur and nearby villages of Gahmar.[3]
In Kam Dev's or Rao Dalpat's family there was one of his 4th generation grandson named Narhar Dev who, influenced by Islam, became a Muslim in year 1542, Being the eldest and most responsible for handling big jagir and Sarkar of the region and he became a nobleman and ruler of this region. His father's name was Puranmal Rao Sakarwar had eight sons among whom he was eldest. Although after Narhar's mother's death, Puranmal married two other women from whom he had six sons, so, Narhar from his childhood days was neglected and so he didn't liked his step mothers.
The legend says, he and his wife weren't having any children, his wife was sitting sad on the waranda of her house she saw a sufi saint, the saint asked for roties and about her problem, of not having any children, she gave five roties to the saint, so he blessed them of having five children. The prayer, blessing or a miracle of a Sufi saint named Saiyyad Shah Juned Qadri worked, they later had five sons in the 1540s named as Jahangir Khan, Barbal Khan, Baran Khan, Usman Khan and Khan Jahan Khan. He recited kalma in Sher Shah Suri 's court where he went to pay up the lagan of his reasat and adopted Islam, getting the title of Khan Bahadur in the year 1542 and became Narhar Khan. Although this act of his was not liked by his father, he removed him from his house and gave him a piece of land near Kamesardih.
He established a new "Jagir" and later got control of his ansistoral regions, after some years, he build his fort at Kamesaradih, from where the place and Kamsar pathans derived their name. He also retained his title of Raja. Narhar Khan was also very influenced by Islam and Sufies his elder son Jahangir Khan also became a Sufi sant whose dargah is at Akhini village of Kamsar. Their descendants established many villages on the banks of Karamnasa and Ganga rivers.[6][7][8][9][10][11][12][3][13]
Zamindari Estate (1540s-late 1600s)
The Kamsaar Jagir was established in the early 16th century, initially consisting of the mauzas of Reotipur, Sherpur,(Qariat Reotipur)and Bara, along with other villages in the region that now form Dildarnagar Kamsar and nearby. The jagir’s origins trace back to Puranmal, a descendant of Kam Dev, who was a prominent figure in the area. His son, Raja Narhar Khan, succeeded him as the chief of the region. Despite converting to Islam, Raja Narhar Khan served as the leader of the Kamsaar Jagir under the Sur Empire and continued to hold power after the Mughal Empire's rise. His leadership marked a period of consolidation, and the jagir became an important center of administration.later, Ali Quli Khan Zaman of Zamania, got the jagir of Ghazipur, while Kamsaar being a important zamindari.
Raja Narhar Khan’s descendants expanded the jagir, with his great-grandson Quttul Khan establishing the Taluka of Seorai, which encompassed 52 villages. He was a Dewan of the Subah, He constructed a fort and an Eidgah, making Seorai a central hub. Following his death in a dispute with Man Singh Rai of Reotipur, his cousin Raja Daud Khan avenged him and assumed control of Dewaitha (then Daudpur) and the Kamsar region succeeding Quttul. Daud Khan strengthened the estate’s political influence, and at its height, Kamsar-O-Bar extended across half of Zamaniatehsil and parts of Ramgarh and Nuaontehsils. Prominent villages like Mircha (formerly Amir Chak) and Dildarnagar (formerly Deendarnagar) also emerged. The family had strong ties with Hetam Khan of Hetampur, the jagirdar of Chandauli, leading to the settlement of Hetam’s descendants in Mania.
Dildarnagar Kamsar has been historically shaped by the contributions of notable leaders like Khan Bahadur Mansur Ali Khan of Gorasara, Deputy Muhammad Syed Khan and Haroon Rashid of Usia, and Maulvi Suleman Khan of Dewaitha. Khan Bahadur Mansur Ali Khan championed the anti-dowry movement through the "Anjuman Islah Kamsar-o-Bar" in 1910, promoting simplicity in weddings and other cultural practises.
