The capital of the dynasty was Bikrampur in present-day Munshiganj District of Bangladesh.

The first ruler of this dynasty was Purushottamadeva, who rose from the position of a village chief (gramani).

His son Madhumathana or Madhusudanadeva was the first independent ruler of this dynasty, who assumed the title of nripati.

The inscriptional evidences show that his kingdom was extended up to the present-day Comilla-Noakhali-Chittagong region.

A later ruler of this dynasty Ariraja-Danuja-Madhava Dasharathadeva extended his kingdom up to Bikrampur and made it his capital.
