During the
1951-52 Lok Sabha elections, Bilaspur,
Durg and
Raipur formed a joint parliamentary constituency. This arrangement continued until the
1956 delimitation, when the areas were separated into present three distinct constituencies. The joint constituency elected two Members of Parliament,
Bhupendra Nath Mishra & Agam Dass Guru. After Guru Agam Das Guru's death in 1955, his wife
Minimata won the subsequent by-election, becoming the third representative from this region. ==Assembly segments==
