How did Henry VII deal with Yorkist pretenders after becoming king?

After ascending the throne in 1485, Henry VII faced persistent challenges from Yorkist pretenders and malcontents who viewed his claim as insecure. His approach to these threats combined military force, political maneuvering, and strategic leniency or imprisonment depending on the nature of the individual.1

• Military Suppression: Henry actively engaged and defeated uprisings, most notably at the Battle of Stoke in 1487, where he crushed the rebellion supporting the pretender Lambert Simnel.12
• Strategic Leniency: Recognizing that Simnel was a mere pawn manipulated by others, Henry displayed sardonic contempt rather than executing him; he instead employed the boy in the royal kitchens.12
• Imprisonment and Containment: For more serious threats, such as Perkin Warbeck and Edmund de la Pole, Henry utilized capture and long-term imprisonment, eventually securing Suffolk in the Tower of London by 1506 to ensure his dynasty's safety.1
• Political Consolidation: To stabilize his rule, Henry married Elizabeth of York, daughter of Edward IV, effectively uniting the houses of York and Lancaster.34
