Overview
Lambert Simnel (c. 1477 – after 1534) was a pretender to the throne of England. In 1487, his claim to be Edward Plantagenet, 17th Earl of Warwick, threatened the newly established reign of Henry VII (1485–1509). Simnel became the figurehead of a Yorkist rebellion organised by John de la Pole, Earl of Lincoln. The rebellion was crushed in 1487. Simnel was pardoned because of his tender years, and was thereafter employed by the royal household as a scullion, and, later, as a Groom of the Stool.
Early life
Simnel was born around 1477. His real name is not known—contemporary records call him John, not Lambert, and even his surname is suspect. Different sources have different claims of his parentage, from a baker and tradesman to an organ builder. Most definitely, he was of humble origin. At the age of about ten, he was taken as a pupil by an Oxford-trained priest named Richard Simon (or Richard Symonds / Richard Simons / William Symonds) who apparently decided to become a kingmaker. He tutored the boy in courtly manners and contemporaries described the boy as handsome. He was taught the necessary etiquette and was well educated by Simon.
Pretender
Simon noticed a striking resemblance between Lambert and the sons of Edward IV, so he initially intended to present Simnel as Richard, Duke of York, son of King Edward IV, the younger of the vanished Princes in the Tower. However, when he heard rumours (at the time false) that the Earl of Warwick had died during his imprisonment in the Tower of London, he changed his mind. The real Warwick was a boy of about the same age, having been born in 1475, and had a claim to the throne as the son of George Plantagenet, 1st Duke of Clarence, King Edward IV's executed brother. Warwick was a touchstone for Yorkist affections, and people still wore his badge of the bear and ragged staff.
According to James A. Williamson, Simnel was merely a figurehead for a rebellion that was already being planned by the Yorkists:
He was merely a commonplace tool to be used for important ends, and the attempt to overthrow Henry VII would have taken place had Simnel never existed. The Yorkist leaders were determined on a serious push, rising of their party in England supported by as great a force as possible from overseas.
