Thomas Percy, 7th Earl of Northumberland, 1st Baron Percy, KG (152822 August 1572) was an English nobleman, politician and Roman Catholic rebel leader, who led the Rising of the North against Elizabeth I in 1569. After the failure of the rising, he was captured in Scotland, sold to the English government and executed for treason. He was later beatified by the Catholic Church.
Early life
Percy was the eldest son of Sir Thomas Percy and Eleanor, daughter of Sir Guiscard Harbottal. He was the nephew of Henry Percy, 6th Earl of Northumberland, with whom Anne Boleyn had a romantic association before she became the wife of King Henry VIII. When Thomas was eight years old his father, Sir Thomas Percy, was executed at Tyburn (2 June 1537) for having taken a leading part in the Pilgrimage of Grace, and he also is considered a martyr by many. Thomas and his brother Henry were then removed from their mother's keeping and entrusted to Sir Thomas Tempest.
In 1549, when Thomas Percy came of age, an Act was passed "for the restitution in blood of Mr. Thomas Percy". Shortly afterwards he was knighted, and, three years later, in Queen Mary I's reign, he regained his ancestral honours and lands. He was returned as Member of Parliament for Westmorland in the Parliament of England called in November 1554. Declared governor of Prudhoe Castle he besieged and took Scarborough Castle, which was seized by rebels in 1557. In reward he was granted the title of Earl of Northumberland and the Baronies of Percy, Poynings, Lucy, Bryan, and Fitzpane were restored to him, on 1 May 1557.
Exile and rendition
After the Rising of the North failed, Thomas fled to Scotland, where he was captured by James Douglas, 4th Earl of Morton, one of the leading Scottish nobles. He was held at Lochleven Castle. Margaret Erskine wrote that her son, William Douglas, Laird of Lochleven, was at Loch Leven, "and it is all frozyn, quha (who) is at greitt charges by resoun of grett company in his houss daylie for the keiping of my Lord of Northumberland".
Elizabeth I sent Henry Gates and William Drury to ask Regent Moray to send the Earl to England. Moray was assassinated at Linlithgow in January 1570 before the negotiations were completed.
In January 1572, Thomas's wife Anne wrote from Mechelen to the Laird of Lochleven hoping in vain to secure his release. There were proposals that their allies would pay a ransom. where he was lodged in After three years, the Earl was sold to the English Government for two thousand pounds. He was taken to Eyemouth by the Laird of Cleish and then to Berwick-upon-Tweed, where he was lodged in Valentine Browne's house on 8 June 1572.
