The foundation of this town was laid by Emperor
Firoz Shah Tughlaq (1351–1388 AD) in 1370 AD, while he was on his way to the shrine of
Saiyyad Salar Masud Ghazi at
Baharaich. At that time, he settled in some
Kayastha and
Muslim families. Around 1400, a local Hindu (
Pasi) strongman, Lahori Pasi, took possession of it and changed its name from Tuglaqpur to Lahoripur, which became Laharpur due to usage. His descendants remained in possession of Laharpur for another 18 years or so. They were exterminated by a Muslim commander, Sheikh Tahir Gazi of
Kannauj in 1418 AD. The town became an important urban center when Raja
Todarmal, the finance minister of Emperor Akbar, reconstituted a new pargana of 765 villages with its administrative center at the town of Laharpur. Muslims ruled the town until the death of Mughal Emperor
Aurangzeb in 1707, when, taking advantage of widespread anarchy across
Mughal Empire, a local Gaur commander, Raja Chandar Sen invaded
Sitapur in 1707. Since then, it remained under the control local Gaur Kshatriyas until 1858 when it came under the rule of
British Crown. ==Geography==
