Kingdom of Ireland

Note: "Because many of the people appointed as Lord Lieutenant of Ireland (sometimes also called "Viceroy") did not always continually remain in office but left the office empty for a period (sometimes to return to the Court of St. James's, sometimes to return to their British estates) before either being replaced or returning, it is difficult to state terms of office with any accuracy. As a result, the date of appointment of each, rather than a specified term of office, is stated in brackets. Though the office existed earlier, because of difficulty in getting clear information this list begins in 1529. In the earlier years, there were frequently long vacancies, during which a Lord Deputy or Lord Justice would act as chief governor."

"The Irish Act of Union merges the Kingdom of Ireland with the Kingdom of Great Britain to form the United Kingdom of Great Britain and Ireland." The new United Kingdom comes into being on January 1, 1801. One result is the disappearance of the separate Irish Parliament. Though many expect the office of Lord Lieutenant to be abolished, it survives, though periodic debates throughout the nineteenth century erupt over whether it should be replaced by a 'Secretary of State for Ireland'. The office of Chief Secretary for Ireland (in effect number two in Irish government ranking) grows in importance, with the Lord Lieutenant gradually reduced to a largely though not completely ceremonial role.
