Thomas Wentworth, 1st Earl of Strafford, English soldier and politician, Lord Lieutenant of Ireland (born 1593)

Thomas Wentworth, 1st Earl of Strafford, was an English statesman and a major figure in the period leading up to the English Civil War. He served in Parliament and was a supporter of King Charles I. From 1632 to 1640 he was Lord Deputy of Ireland, where he established a strong authoritarian rule. Recalled to England, he became a leading advisor to the King, attempting to strengthen the royal position against Parliament. When Parliament condemned Lord Strafford to death, Charles reluctantly signed the death warrant and Strafford was executed. He had been advanced several times in the Peerage of England during his career, being created 1st Baron Wentworth in 1628, 1st Viscount Wentworth in late 1628 or early 1629, and, finally, 1st Earl of Strafford in January 1640. He was known as Sir Thomas Wentworth, 2nd Baronet, between 1614 and 1628.

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.
