Ralph Percy, 12th Duke of Northumberland

Ralph George Algernon Percy, 12th Duke of Northumberland, (born 16 November 1956), styled Lord Ralph Percy until 1995, is a British hereditary peer and rural landowner and current head of the House of Percy.

Early life
Ralph Percy was born the second son (and one of seven children) of Hugh Percy, 10th Duke of Northumberland, and the former Lady Elizabeth Diana Montagu Douglas Scott, daughter of the 8th Duke of Buccleuch. His maternal first cousin is Richard Scott, 10th Duke of Buccleuch, one of the largest private landowners in Scotland, while his paternal first cousin was Angus Douglas-Hamilton, 15th Duke of Hamilton, who was the premier peer of Scotland. His first cousins once removed are Prince Richard, Duke of Gloucester and Prince William of Gloucester, members of the British royal family.

Percy was educated at Eton College, Christ Church, Oxford, where he graduated in modern history, and Reading University, where he studied land management. He worked in the Arundel Castle estate office for seven years, before moving back to Northumberland to manage the Alnwick estate for his elder brother Henry, the 11th Duke.

Duke
Ralph Percy succeeded in the dukedom in 1995 on the death of the 11th duke, who had no children. As such, he was a member of the House of Lords until the passing of the House of Lords Act 1999 ended the right of hereditary peers to sit in the House. Hansard records no contributions to House of Lords work by Northumberland.

The Duke assists in managing Northumberland Estates (the corporation holding the ducal assets) which has many venture subsidiaries and associated trusts, which altogether own land and property in Northumberland, Scotland and to a lesser extent London, Surrey and Tyneside. Ralph Percy was ranked at number 285 in the Sunday Times Rich List 2024, with an estimated wealth of £509 million. He or the corporation is the owner of Alnwick Castle, an ancestral ducal seat, as well as Warkworth Castle and Prudhoe Castle in Northumberland; Syon House and Syon Park in London; Hulne Park and Hulne Priory at Alnwick; Albury Park in Surrey, and other listed buildings such as Brizlee Tower. Northumberland Estates manages 100000 acres: directly managing 4000 acres of forestry and 20000 acres of farmland, with approximately 100 tenant farmers managing the remaining bulk of the land.

The 12th Duke's sale on the open market, rather than at a lower price to The National Gallery, of Raphael's Madonna of the Pinks in 2003 was subject to some criticism. At much the same time, in response to a foot-and-mouth disease crisis, the Duke cut the rents of tenant farmers by 10 percent. The Duke has shown opposition to certain wind farms. However, he adopted renewable energy in the restoration of a hydroelectric power generator. The Duke is a sponsor of the NCEA Duke's Secondary School.

On 8 April 2014, despite the vast wealth of the estate, the estate's management announced the date of a new art sale to raise £15 million to cover the costs of the Newburn flood caused by the failure of a culvert for which it was responsible on 25 September 2012. The sales were completed by Sotheby's in July 2014.

In 2015 the Percy family outraged users of allotments in Hounslow, West London, when they revoked a lease which had existed since the First World War, with the intent of developing the land for profit. The development plans were rejected by the planning Inspectorate in 2023 on grounds it would harm heritage assets.

Marriage and children
Northumberland married Jane Richard on 21 July 1979 at Traquair Parish Church. They have four children:


 * Lady Catherine Sarah "Katie" Percy (born 23 June 1982), a gunsmith and mechanic
