Kishanganj district, a part of Purnia division is a district of Bihar state with its administrative headquarters located at Kishanganj town. It is believe that earlier the district of Kishanganj was a part of Purnia district, a part of the Mithila region. For the first time Mithila came into the limelight after being settled by Indo-Aryan peoples who set up the Mithila Kingdom (also popularly known as Kingdom of the Videhas). During the late Vedic period i.e. (c. 1100-500 BCE), the kingdom of the Videhas along with Kuru and Pancala rose up as one of the major political and cultural centers of South Asia. At that time the kings of the Kingdom of the Videhas were well-known as Janakas. There is also an interesting story associated with the name of the district. During the period of Mohammed Fakiruddin, a Khagada Nawab, one Hindu saint arrived at his place and wanted to rest since he was tried. But he refused to enter at the place when he heard that the name of the place is Alamganj, the name of the river name is Ramzan and the name of the Jamindar is Fakiruddin. Then the Nawab made a separate region, started from Kishanganj Gudri to Ramzan pool and named it Kishanganj. At the time of Mughal era Kishanganj district was a part of Nepal and was popularly known as Nepalgarh. Mohammed Raza, a Mughal administrator captured the fort of Nepalgarh and changed its name to Alamganj. It is the oldest and most important sub-division of Purnia district.
