Although Henry VII., soon after he attained the throne, married Elizabeth of York, daughter of Edward IV., and thus united the two rival houses, the Yorkists were discontented with his rule. "With the help of Margaret of Burgundy, Edward IV. 's sister, and James IV. of Scotland, they actually set up two impostors, one after the other, to claim the throne. There was a real heir of the House of York still alive--young Edward, Earl of Warwick [son of the Duke of Clarence, brother to Edward IV.], ... and Henry had taken the precaution to keep him in the Tower. But in 1487 a sham Earl of Warwick appeared in Ireland, and being supported by the Earl of Kildare, was actually crowned in Dublin Cathedral. Henry soon put down the imposture by showing the real earl to the people of London, and defeating the army of the pretended earl at Stoke, near Newark, June, 1487. He proved to be a lad named Lambert Simnel, the son of a joiner at Oxford, and he became a scullion in the king's kitchen." In 1492 another pretender of like character was brought forward. "A young man, called Perkin Warbeck, who proved afterwards to be a native of Tournay, pretended that he was Richard, Duke of York, the younger of the two little princes in the Tower, and that he had escaped when his brother Edward V. was murdered. He persuaded the king of France and Margaret of Burgundy to acknowledge him, and was not only received at the foreign courts, but, after failing in Ireland, he went to Scotland, where James IV. married him to his own cousin Catharine Gordon, and helped him to invade England in 1496. The invasion was defeated however, by the Earl of Surrey, and then Perkin went back to Ireland, where the people had revolted against the heavy taxes. There he raised an army and marched to Exeter, but meeting the king's troops at Taunton, he lost courage, and fled to the Abbey of Beaulieu, where he was taken prisoner, and sent to the Tower in 1497." In 1501 both Perkin Warbeck and the young Earl of Warwick were executed. _A. B. Buckley, History of England for Beginners, chapter 13._ ALSO IN: _J.
