Rebellions:

Cause: Yorkist opposition to Henry VII's rule after his victory at Bosworth.
Key Figures: Francis Lovell, Humphrey and Thomas Stafford.
Events: Lovell attempted to raise a rebellion in the Midlands, while the Staffords tried in the West.
Outcome: The rebellion failed due to lack of widespread support. Lovell fled, and the Staffords were captured. Henry's use of pardons and swift retaliation showcased his authority.
Threat: Minimal—Henry was newly established, but the rebellion lacked serious backing.

Cause: Yorkist plot to place a pretender on the throne; Simnel was presented as Edward, Earl of Warwick.
Key Figures: Lambert Simnel, Richard Symonds (tutor), John de la Pole, Earl of Lincoln.
Events: Supported by Margaret of Burgundy, an army of Irish mercenaries landed in Lancashire. The rebels were defeated at the Battle of Stoke.
Outcome: Henry won decisively, captured Simnel, and employed him as a kitchen servant. This solidified his position as king.
Threat: Significant—large-scale military engagement; but ultimately failed to gather widespread support.

Cause: Opposition to taxation for a campaign to aid Brittany in resisting France.
Key Figures: Sir John Egremont, Earl of Northumberland (killed during the revolt).
Events: Yorkshire refused to pay the tax, leading to a rebellion. Henry Percy, Earl of Northumberland, was murdered by rebels.
Outcome: Rebellion was crushed by the Earl of Surrey. Henry did not collect the tax, showing compromise.
Threat: Moderate—limited to Yorkshire, but highlighted regional resentment towards Henry's fiscal policies.

Cause: Opposition to taxation to fund a campaign against Scotland.
Key Figures: Lord Audley, Thomas Flamank, Michael An Gof (leaders).
Events: Rebels marched from Cornwall to Blackheath, near London. Henry VII raised an army to suppress them.
Outcome: The rebellion was defeated at the Battle of Blackheath. The leaders were executed.
Threat: Significant—posed a direct threat to London but lacked coordinated support and military strength.

Cause: Yorkist support for Warbeck, who claimed to be Richard, Duke of York, one of the Princes in the Tower.
Key Figures: Perkin Warbeck, Margaret of Burgundy, King James IV of Scotland.
Events: Warbeck gained support from foreign powers (Burgundy, Scotland). His invasion attempts in 1495, 1496, and 1497 all failed.
Outcome: Warbeck was captured in 1497 and executed in 1499 after attempting to escape. Henry’s security increased after dealing with the foreign threats.
Threat: Moderate—foreign involvement was a concern, but Warbeck never managed to rally significant domestic support.
