There were a number of influences on fascism from the Renaissance era in Europe. Niccolò Machiavelli is known to have influenced Italian Fascism, particularly through his promotion of the absolute authority of the state. Machiavelli rejected all existing traditional and metaphysical assumptions of the time—especially those associated with the Middle Ages—and asserted as an Italian patriot that Italy needed a strong and all-powerful state led by a vigorous and ruthless leader who would conquer and unify Italy. Mussolini saw himself as a modern-day Machiavellian and wrote an introduction to his honorary doctoral thesis for the University of Bologna—"Prelude to Machiavelli". Mussolini professed that Machiavelli's "pessimism about human nature was eternal in its acuity. Individuals simply could not be relied on voluntarily to 'obey the law, pay their taxes and serve in war'. No well-ordered society could want the people to be sovereign". Most dictators of the 20th century mimicked Mussolini's admiration for Machiavelli and "Stalin... saw himself as the embodiment of Machiavellian "virtù"".
