Charles James Fox PC, styled The Honourable from 1762, was a prominent British Whig statesman whose parliamentary career spanned thirty-eight years of the late 18th and early 19th centuries and who was particularly noted for being the arch-rival of William Pitt the Younger. His father was a leading Whig and Fox rose to prominence in the House of Commons as a forceful and eloquent speaker with a notorious and colourful private life, though his opinions were rather conservative and conventional. However, with the coming of the American War of Independence and the influence of the Whig Edmund Burke, Fox's opinions evolved into some of the most radical ever to be aired in the Parliament of his era.
Fox became a prominent and staunch opponent of George III, whom he regarded as an aspiring tyrant; he supported the American Patriots, even dressing in the colours of George Washington's army. Briefly serving as Britain's first Foreign Secretary in the ministry of the Marquess of Rockingham in 1782, he returned to the post in a coalition government with his old enemy Lord North in 1783. However, the King forced Fox and North out of government before the end of the year, replacing them with the twenty-four-year-old Pitt the Younger, and Fox spent the following twenty-two years facing Pitt and the government benches from across the Commons.
