Lionel Cranfield Sackville, 1st Duke of DorsetKGPC (18 January 1688 – 10 October 1765) was an English peer and politician who served as Lord President of the Council from 1745 to 1751. He also twice served as Lord Lieutenant of Ireland from 1730 to 1737 and again from 1750 to 1755.
Dorset served twice as Lord Lieutenant of Ireland, from 1731 to 1737 and again from 1751 to 1755. In 1739, at the foundation of the Foundling Hospital, he was one of that charity's original governors. His first term as Lord Lieutenant was uneventful. His second took place at a time of acute political tension between the two main factions in the Irish Government, one led by Henry Boyle, the Speaker of the Irish House of Commons, the other by George Stone, the Anglican Archbishop of Armagh. Dorset, now heavily influenced by his son George Sackville, made the mistake of openly backing the Archbishop. He was unable to oust Boyle from power, and was accused of being the Archbishop's tool. He became extremely unpopular, leading to his eventual recall.
The current O'Connell Street in Dublin was named in his honour Sackville Street until 1924.
Last years
His last years were uneventful, apart from a riot in 1757 caused by the passage of the Militia Act to raise an army for the Seven Years' War, in which he narrowly escaped injury. He died at Knole on 9 October 1765 and was buried at Withyham in Sussex.
Character
Horace Walpole gave this sketch of his character: "with the greatest dignity in his appearance, he was in private the greatest lover of buffoonery and low company.... he was never thought to have wanted a tendency to power, in whatever hands it was, or was likely to be". Jonathan Swift thought him one of the most agreeable and well-informed men, and best conversationalists, he had ever met. Even harsh critics admitted his dignity and perfect decorum, a last legacy of the manners of the Court of Queen Anne.
