Henry Flood was an Irish statesman and Lord Chief Justice of the King's Bench for Ireland. He was educated at Trinity College Dublin, and afterwards at Christ Church, Oxford, where he became proficient in the classics. He was a leading Irish politician, and a friend of Henry Grattan, the leader of the Irish Patriot Party. He became an object of public interest in 1770, when he was put on trial for murder, after killing a political rival in a duel.

Henry Grattan was an Irish politician and lawyer who campaigned for legislative freedom for the Irish Parliament in the late 18th century from Britain. He was a Member of the Irish Parliament (MP) from 1775 to 1801 and a Member of Parliament (MP) in Westminster from 1805 to 1820. He has been described as a superb orator and a romantic. With generous enthusiasm he demanded that Ireland should be granted its rightful status, that of an independent nation, though he always insisted that Ireland would remain linked to Great Britain by a common crown and by sharing a common political tradition.
