Before the de-limitation exercise in 2010, large parts of what is today the Agiaon Assembly Constituency in Bhojpur were part of Sahar constituency which was represented for three consecutive terms by the legendary leader of Bhojpur, Comrade Ramnaresh Ram. Today, Agiaon is dotted with memorials and plaques marking the martyrdom of comrades in the struggle against feudalism and for social dignity of Dalits and the rural poor.
