What is the theme in Edward II: The Troublesome Reign and Lamentable End of Edward the Second, King of England, with the Tragical Fall of Proud Mortimer by Christopher Marlowe?

Politics: Machiavellian Style is a theme in the book. In Elizabethan England, Niccolo Machiavelli's // Principe (The Prince, 1505) was considered a treatise on the science of evil statesmanship because it outlined how a cunning tyrant could, through brutal and forceful measures, take and maintain control over a region and a people. In fact, it seemed a veritable handbook for tyranny, with its exhortation that "It is necessary for a prince wishing to hold his own to know how to do wrong, and to make use of it or not according to necessity."
