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, Warren Hastings, and became directly involved in governance. The Company ruled until 1858, when, after the Indian Rebellion of 1857 and the Government of India Act 1858, the India Office of the British government assumed the task of directly administering India in the new British Raj.

Warren Hastings was a British colonial administrator, who served as the first Governor of the Presidency of Fort William (Bengal), the head of the Supreme Council of Bengal, and so the first Governor-General of Bengal in 1772–1785. He and Robert Clive are credited with laying the foundation of the British Empire in India. He was an energetic organizer and reformer. In 1779–1784 he led forces of the East India Company against a coalition of native states and the French. In the end, the well-organized British side held its own, while France lost influence in India. In 1787, he was accused of corruption and impeached, but he was eventually acquitted in 1795 after a long trial. He was made a Privy Councillor in 1814.
