Social equation
The constituency was represented by only two parliamentarians till 1980. Bali Ram Bhagat, who hailed from Yadav caste and Chandradeo Prasad Verma, who was a member of Kushwaha (Koeri) caste were the parliamentarians, who had the distinction of getting elected from this seat for multiple times. After these two parliamentarians, the constituency elected different candidates everytime in next elections till 2009. This constituency is known for struggle between some caste groups for getting their men elected in Indian General Elections to Lok Sabha from the first General Elections itself.[1]
Until 2004, only Yadav and Koeri candidates were elected in different elections, except in 1989, when Rameshwar Prasad, a member of Extremely Backward Caste was elected on the symbol of Indian People's Front. In 1996, 1998 and 1999 elections, Chandradeo Prasad Verma, Haridwar Prasad Singh and Ram Prasad Kushwaha, all three belonging to Koeri caste were elected from this constituency. From 2009 onwards, the candidates belonging to Rajput caste are getting elected.[1][2]
