Bangarmau is a tehsil and a municipal board in Unnao district in the state of Uttar Pradesh, India.

[3] Bangarmau was the first Hindu settlement in the area of present-day Unnao district, dating back to around the year 1300.

[2] Ala-ud-Din's descendants remain custodians of the shrine, which at one point was "rich and famous" before declining by the turn of the 20th century.

[2] At the turn of the 20th century, Bangarmau was described as a well-built town almost surrounded by extensive orchards; about half the houses were built with brick.

[2] The town held markets twice weekly, on Tuesdays and Saturdays; its commerce was helped by its advantageous location at a crossroads.
