Ugu is said to have been founded and populated by Raja Ugarsen, a Panwar Chhatri from Kannauj; the ruins of his palace and courthouse are still extant. His descendants ruled here until 806 AH, when they were defeated and overthrown by Ibrahim Shah Sharqi of the Jaunpur Sultanate. They were then replaced by Kurmi pattidars, who maintained possession of the village through the 20th century.

At the turn of the 20th century, Ugu was described as a very large and prosperous village, "almost completely surrounded by groves". It had a lower primary school attended by 60 students, as well as three temples and the ruins of Ugarsen's palace and courthouse. Its population in 1901 was recorded as 4,640, including 4,443 Hindus and 197 Muslims. Around 30% of the total population belonged to the Brahmin community.
