Answer
Kett's Rebellion, led by Robert Kett, was a significant uprising in 1549 that challenged religious and economic changes implemented under Edward VI. John Dudley, the Duke of Northumberland and Lord Protector of England, played a crucial role in suppressing the rebellion. Dudley raised an army and marched against the rebels, eventually defeating them in a battle at Dussindale. Kett himself was captured and executed, and the rebellion was effectively crushed.
