The Regulating Act 1773 created the office with the title of Governor-General of Presidency of Fort William, or Governor-General of Bengal to be appointed by the Court of Directors of the East India Company (EIC).Following the adoption of the Government of India Act 1858, the Governor-General representing the Crown became known as the Viceroy.The designation 'Viceroy', although it was most frequently used in ordinary parlance, had no statutory authority, and was never employed by Parliament.Although the Proclamation of 1858 announcing the assumption of the government of India by the Crown referred to Lord Canning as "first Viceroy and Governor-General", none of the Warrants appointing his successors referred to them as 'Viceroys', and the title, which was frequently used in Warrants dealing with precedence and in public notifications, was one of ceremonies used in connection with the state and social functions of the Sovereign's representative.The office of Governor-General continued to exist as a ceremonial post in each of the new dominions of India and Pakistan, until they adopted republican constitutions in 1950 and 1956 respectively.
