Company rule in India was the rule of the British East India Company on the Indian subcontinent. This is variously taken to have commenced in 1757, after the Battle of Plassey, when the Nawab of Bengal Siraj-ud-Daulah was defeated and replaced with Mir Jafar, who had the support of the East India Company; or in 1765, when the Company was granted the diwani, or the right to collect revenue, in Bengal and Bihar; or in 1773, when the Company abolished local rule (Nizamat) in Bengal and established a capital in Calcutta, appointed its first Governor-General of Fort William, Warren Hastings, and became directly involved in governance.
