The Regulating Act (1773) and William Pitt the Younger India Act (1784) established government control of political policy through a regulatory board for Parliament. The company then gradually lost commercial and political control. Its commercial monopoly was broken in 1813. In 1833, the jealouslyprotected monopoly of the East India Company was finally abolished and the China trade was opened to the competition of dozens of British companies, who had been petitioning the government, and from 1834 it was the only managing agency for the British Government of India. It was deprived of that role after the Indian Rebellion (1857), and it did not exist as a legal entity in 1873.
