Robert Devereux, 2nd Earl of Essex, English general and politician, Lord Lieutenant of Ireland (born 1566)

Robert Devereux, 2nd Earl of Essex was an English nobleman, soldier and a favourite of Queen Elizabeth I.

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.
