Political career
In 1780, Sheridan entered the House of Commons as the ally of Charles James Fox on the side of the American Colonials in the political debate of that year. He is said to have paid the burgesses of Stafford five guineas apiece to allow him to represent them. As a consequence, his first speech in Parliament was a defence against the charge of bribery.
In 1787 Sheridan demanded the impeachment of Warren Hastings, the first Governor-General of India. His speech in the House of Commons was described by Edmund Burke, Charles James Fox, and William Pitt as the greatest ever delivered in ancient or modern times.
In Commons, Sheridan was known as an engaging, and often entertaining orator. His speeches at the Hastings impeachment were later published as a 59-page booklet. In 1793, during the debates on the Aliens Act designed to prevent French Revolutionary spies and saboteurs from flooding into the country, Edmund Burke made a speech in which he claimed there were thousands of French agents in Britain ready to use weapons against the authorities. To dramatically emphasise his point he threw down a knife onto the floor of the House of Commons. Sheridan shouted, "Where's the fork?", which led to much of the house collapsing in laughter.
In April 1798 he appeared at the trial in Maidstone of United Irishmen accused of treasonable conspiracy with the French. Along with Charles James Fox, Lord Moira and other radical Whig grandees, he testified on behalf of Arthur O'Connor. O'Connor was acquitted. His companion, Father James Coigly was hanged.
During the invasion scare of 1803 Sheridan penned an 'Address to the People':
THEY, by a strange Frenzy driven, fight for Power, for Plunder, and extended Rule—WE, for our Country, our Altars, and our Homes.—THEY follow an ADVENTURER, whom they fear—and obey a Power which they hate—WE serve a Monarch whom we love—a God whom we adore...They call on us to barter all of Good we have inherited and proved, for the desperate Chance of Something better which they promise.—Be our plain Answer this: The Throne WE honour is the PEOPLE'S CHOICE—the Laws we reverence are our brave Fathers' Legacy—the Faith we follow teaches us to live in bonds of Charity with all Mankind, and die with Hope of Bliss beyond the Grave. Tell your Invaders this; and tell them too, we seek no Change; and, least of all, such Change as they would bring us.
He held the posts of Receiver-General of the Duchy of Cornwall (1804–1807) and Treasurer of the Navy (1806–1807). Sheridan was noted for his close political relationship with the Prince of Wales, leading a faction of his supporters in the Commons. By 1805 when the Prince was cooling on his previous support of Catholic Emancipation Sheridan, George Tierney and others announced their own opposition to it.
When, after 32 years in Parliament, he lost re-election in 1812, his creditors closed in on him and his last years were harassed by debt and disappointment. On hearing of his debts, the American Congress offered Sheridan £20,000 in recognition of his efforts to prevent the American War of Independence. He refused the offer.
