What was the name of the largest rebellion ever faced by a Tudor?

The largest rebellion faced by a Tudor monarch was the Pilgrimage of Grace in 1536. It was a widespread uprising in Northern England, largely in response to the Dissolution of the Monasteries and various grievances against King Henry VIII's policies. The rebellion involved tens of thousands of participants and highlighted significant social, economic, and religious discontent during the Tudor period. Ultimately, it was suppressed, but it revealed the deep divisions within English society at the time.
