In 1717, at 23, Newcastle first attained high political office as Lord Chamberlain of the Household and was given the responsibility of overseeing theatres. Plays were often extremely political, and Newcastle was tasked with suppressing any plays or playwrights that he believed to be too critical of the Hanoverian succession or the Whig government. Newcastle clashed repeatedly with Sir Richard Steele, a leading playwright. In 1719, he was one of the three main investors in George Frideric Handel's new opera company, the Royal Academy of Music. The Duke ordered Handel in May 1719 to go to the Continent to contract singers for as long as possible.
