Bihar under the Delhi Sultanate, Mughals and the Eighteenth-Century Transition

BPSC demand

Keep Bihar at the centre: conquest, Afghan resurgence, Mughal provincial organisation and the transition to Bengal’s influence. Use source-supported anchors rather than sweeping claims: Bakhtiyar Khalji, Tirhut/Mithila, Sasaram, Patna, Akbar’s Subah of Bihar, and Buxar.
