The impeachment of Warren Hastings was a failed attempt between 1788 and 1795 to impeach the first Governor-General of India in the Parliament of Great Britain. Hastings was accused of misconduct during his time in Calcutta particularly relating to mismanagement and personal corruption. The prosecution was led by Edmund Burke and became a wider debate about the role of the East India Company and the expanding empire in India.
The trial did not sit continuously and the case dragged on for seven years. When the eventual verdict was given Hastings was overwhelmingly acquitted. It has been described as "probably the British Isles' most famous, certainly the longest, political trial".
Born in 1732, Warren Hastings spent much of his adult life in India after first travelling out as a clerk of the East India Company in 1750. Hastings developed a reputation as an "Indian" who sought to use traditional Indian methods of governance to run British India rather than the policy of importing European-style law, government and culture favoured by many of his colleagues and representatives of other colonial powers in India. After working his way through the ranks of the Company he was appointed in 1773 as Governor General, a new position that had been created by the North government in order to improve the running of British India. The old structure of rule had come under strain as the Company's holdings had expanded in recent decades from isolated trading posts to large swathes of territory and population.
The powers of the Governor General were balanced out by the establishment of a Calcutta Council which had the authority to veto his decisions. Hastings spent much of his time in office marshalling his own supporters on the Council in an effort to avoid being outvoted.
