The Treaty of Alinagar was signed in 1757 between the British East India Company and Siraj-ud-daulah, the Nawab of Bengal. The treaty restored favorable terms to the British after their capture of Calcutta. Mir Jafar later replaced Siraj-ud-daulah after the Battle of Plassey, while Shah Alam and Bahadur Shah Zafar were Mughal emperors from a different period.
