Henry Paget, 1st Marquess of Anglesey, English general and politician, Lord Lieutenant of Ireland (died 1854)

Henry William Paget, 1st Marquess of Anglesey, styled Lord Paget between 1784 and 1812 and known as the Earl of Uxbridge between 1812 and 1815, was a British Army officer and politician. After serving as a member of parliament for Carnarvon and then for Milborne Port, he took part in the Flanders Campaign and then commanded the cavalry for Sir John Moore's army in Spain during the Peninsular War; his cavalry showed distinct superiority over their French counterparts at the Battle of Sahagún and at the Battle of Benavente, where he defeated the elite chasseurs of the French Imperial Guard. During the Hundred Days he led the charge of the heavy cavalry against Comte d'Erlon's column at the Battle of Waterloo. At the end of the battle, he lost part of one leg to a cannonball. In later life, he served twice as Master-General of the Ordnance and twice as Lord Lieutenant of Ireland.

Lord Lieutenant of Ireland, or more formally Lieutenant General and General Governor of Ireland, was the title of the chief governor of Ireland from the Williamite Wars of 1690 until the Partition of Ireland in 1922. This spanned the Kingdom of Ireland (1541–1800) and the United Kingdom of Great Britain and Ireland (1801–1922). The office, under its various names, was often more generally known as the Viceroy, and his wife was known as the vicereine. The government of Ireland in practice was usually in the hands of the Lord Deputy up to the 17th century, and later of the Chief Secretary for Ireland.
