Bikrampur ("City of Courage") was a pargana situated south of Dhaka, the modern capital city of Bangladesh. In the present day, it is known as the Munshiganj District of Bangladesh. It is a historic region in Bengal and was a part of the Bhawal Estate.
Ashoka, the emperor of the Maurya Dynasty, ruled all of major parts of Bengal from 269 BC to 232 BC. Being a devotee of Gautama Buddha, he propagated Buddhism across his kingdom which included Bikrampur to the east. Following the high ideals of this religion, Pala Kings came to Bikrampur to rule the region.
The the region is successively ruled by Vigrahapala I, Narayanapala, Rajyapala, Gopala II, Vigrahapala II, Mahipala, Naya Pala, Vigrahapala III, Mahipala II, Shurapala II, Ramapala, Kumarapala, Gopala III and Madanapala. Pala empire disintegrated in 1174 weakened by attacks of the Sena dynasty.
During the rule of Srichandra (reigned 930 – 975 AD), the administrative centre of the Chandra kingdom was established at Bikrampur. The Varman Dynasty (1035-1150 CE) replaced Chandras and established their independent kingdom.
After the fall of Chandras, The Varmans Dynasty became powerful in East Bengal. The Varmans claimed that they descended from a branch of Yadava Dynasty of Simhapur. Jat Varman, Hari Varman Samala Varman were the powerful rulers, who ruled in Bikrampur. Bhoja Varman was the last independent ruler of Varman Dynasty who was defeated by Vijaysena of Sena Dynasty.
A copper-plate inscription from the time of the ruler Vijay Sen (ruled 1097–1160), founder of Sen dynasty, was found in Barrackpore, in 1911. In this inscription, Bikrampur was mentioned as the capital of that region. It continued to be the capital throughout the, Sena Dynasty. In 1205, Turkic invader Bakhtiyar Khalji defeated the then-ruler Lakshman Sen in Nadia. Lakshman fled to Bikrampur. His two sons Vishwarup Sen and Keshab Sen kept ruling from here until 1230. But the copper-plate inscriptions during their reign do not mention Bikrampur as the capital.
