 Though the House of Lancaster had been extinguished, the Lancastrian sympathisers survived, who now rallied behind Henry Tudor, a descendant of the Beauforts, a legitimized branch of the House of Lancaster.Moreover, the family of Edward IV, and the Edwardian loyalists, were naturally opposed to him, essentially dividing his Yorkist power base.A coup attempt failed in late 1483, but in 1485 Richard met Henry Tudor at the battle of Bosworth Field.
