The Tudors as a dynasty executed many people, both high and low. But the nobility were the ones consistently involved in treason, either deliberately or unconsciously. Exploring the long sixteenth century under each of the Tudor monarchs gives a sense of how and why so many were executed for what was considered the worst possible crime and how the definition of treason changed over the period. This book examines how and why Tudor nobles like Edward Stafford, 3rd Duke of Buckingham; Queen Consort Anne Boleyn; Henry Howard, Earl of Surrey; and Robert Devereux, 2nd Earl of Essex, fell into the trap of treason and ended up on the block under the executioner’s axe. Treason and the Tudor nobility seem to go hand in hand as, by the end of the sixteenth century and the advent of the Stuart dynasty, no dukes remained in England. How did this happen and why?
