Before the 2008 delimitation, Bankipur was known as Patna West, the constituency from which maverick Congress leader Mahamaya Prasad Sinha defeated the incumbent Chief Minister Krishna Ballabh Sahay in the watershed 1967 assembly election, paving the way for him to become Bihar’s first non-Congress Chief Minister. The verdict effectively led to the beginning of the decline of Congress’s political dominance in Bihar and ushered in the state’s first experiment with coalition politics, bringing together parties as ideologically diverse as the Jana Kranti Dal, the Samyukta Socialist Party, the Bharatiya Jana Sangh and the Communist Party of India. Patna West also elected Thakur Prasad, one of the founding leaders of the Bharatiya Jana Sangh and a prominent RSS figure in the 1977 assembly elections, underscoring the constituency’s enduring role in the evolution of the BJP’s politics in the state. It is perhaps no coincidence then that the constituency remained a BJP bastion for three decades. From 1995 until this by-election, the seat was held continuously by the father-son duo of Nabin Kishore Prasad Sinha and Nitin Nabin, a rare feat of political continuity in Bihar’s otherwise volatile electoral landscape. In retrospect, Bankipur, formerly Patna West, is one of the most decisive electoral arenas where Bihar’s changing political order reveals itself.
