Husseypur is a village in the district of Gopalganj in 2020’s Bihar located on the eastern banks of the Jharahi river. Established in the later part of the seventeenth century by Raja Kshem Karan Bahadur Sahi after he moved his capital from Kalyanpur.
Initially Husseypur was a fort built by Raja Kshem Karan Bahadur Sahi and his successors expanded the fort and developed the village until the reign of Raja Fateh Bahadur Sahi. The halt on expansion was due to relocation of the capital by Raja Fateh Bahadur Sahi after his refusal to accept the suzernity of British thus being forced to leave Husseypur. Later, the British destroyed the fort towards the end of the eighteenth century putting an end to the vibrant centre with a significant military importance.
As of 2020, the ruins of the fort still dot the area on the east bank of river Jharahi and a statue of goddess Saiyya  beneath an old ficus tree is all that remains.
