The Zamindars of Bihar were the autonomous and semiautonomous rulers and administrators of the Mughal subah of Bihar and later during British rule. The zamindars of Bihar were numerous and could be divided into small, medium and large depending on how much land they controlled. Within Bihar, the zamindars had both economic and military power. Each zamindari would have their own standing army which was typically composed of their own clansmen. The majority of these zamindars usually belonged to upper-caste Hindu communities such as Rajputs, Maithil Brahmins, Bhumihars, Kayasthas or Muslims.
