The constituency encompasses Goalanda and Rajbari Sadar upazilas.
The constituency was created in 1984 from a Faridpur constituency when the former Faridpur District was split into five districts: Rajbari, Faridpur, Gopalganj, Madaripur, and Shariatpur.
Kazi Keramat Ali was re-elected unopposed in the 2014 general election after opposition parties withdrew their candidacies in a boycott of the election.
Md. Abdul Wajed Chowdhury died in office. Kazi Keramat Ali was elected in an October 1992 by-election.
