Viscount Moore of Drogheda

Earl of Drogheda is a title in the Peerage of Ireland. It was created in 1661 for Henry Moore, 3rd Viscount Moore.

The Moore family descends from Sir Garrett Moore, a staunch friend of Hugh O'Neill, the Great Earl of Tyrone, whose submission he facilitated, hosting the negotiations that led to the Treaty of Mellifont in 1603 and ending The Nine Years' War. He represented Dungannon in the Irish House of Commons, and served as President of Munster. In 1616 he was raised to the Peerage of Ireland as Baron Moore, of Mellefont in the County of Louth. He was further honoured in 1621 when he was made Viscount Moore, of Drogheda, also in the Peerage of Ireland. He was succeeded in 1628 by his son Charles, the second Viscount, who was killed at the Battle of Portlester while fighting for Charles I in the English Civil War. Charles was succeeded by his son Henry, the aforementioned third Viscount, who was raised to an earldom, as Earl of Drogheda, in 1661. The first Earl's younger son Henry, the third Earl (who succeeded his elder brother in 1679), assumed the additional surname of Hamilton upon succeeding to the estates of his brother-in-law, Henry Hamilton, 2nd Earl of Clanbrassil. In a feast of egotism, he built and named Henry Street, Moore Street, Earl Street, Of (or Off) Lane (now Henry Place, and an important escape route for the volunteers fleeing the GPO in 1916) and Drogheda Street (part of what is now O'Connell Street).

The third Earl was succeeded by his grandson Henry, the fourth Earl. The latter died without surviving children at an early age and was succeeded by his younger brother, Edward, the fifth Earl, who had previously represented Dunleer in the Irish Parliament. Edward's son and successor, Charles, the sixth Earl, was a distinguished soldier and politician. In 1791 he was created Marquess of Drogheda in the Peerage of Ireland. In 1801 he was also made Baron Moore, of Moore Place in the County of Kent, in the Peerage of the United Kingdom, which entitled him to an automatic seat in the English House of Lords.
