Influence

To quote Robert Bireley:

...there were in circulation approximately fifteen editions of the Prince and nineteen of the Discourses and French translations of each before they were placed on the Index of Paul IV in 1559, a measure which nearly stopped publication in Catholic areas except in France. Three principal writers took the field against Machiavelli between the publication of his works and their condemnation in 1559 and again by the Tridentine Index in 1564. These were the English cardinal Reginald Pole and the Portuguese bishop Jeronymo Osorio, both of whom lived for many years in Italy, and the Italian humanist and later bishop, Ambrogio Caterino Politi.

Machiavelli's ideas had a profound impact on political leaders throughout the modern west, helped by the new technology of the printing press. During the first generations after Machiavelli, his main influence was in non-republican governments. Pole reported that The Prince was spoken of highly by Thomas Cromwell in England and had influenced Henry VIII in his turn towards Protestantism, and in his tactics, for example during the Pilgrimage of Grace. A copy was also possessed by the Catholic king and emperor Charles V. In France, after an initially mixed reaction, Machiavelli came to be associated with Catherine de' Medici and the St. Bartholomew's Day massacre. As Bireley (1990:17) reports, in the 16th century, Catholic writers "associated Machiavelli with the Protestants, whereas Protestant authors saw him as Italian and Catholic". In fact, he was apparently influencing both Catholic and Protestant kings.

One of the most important early works dedicated to criticism of Machiavelli, especially The Prince, was that of the Huguenot, Innocent Gentillet, whose work commonly referred to as Discourse against Machiavelli or Anti Machiavel was published in Geneva in 1576. He accused Machiavelli of being an atheist and accused politicians of his time by saying that his works were the "Koran of the courtiers", that "he is of no reputation in the court of France which hath not Machiavel's writings at the fingers ends". Another theme of Gentillet was more in the spirit of Machiavelli himself: he questioned the effectiveness of immoral strategies (just as Machiavelli had himself done, despite also explaining how they could sometimes work). This became the theme of much future political discourse in Europe during the 17th century. This includes the Catholic Counter Reformation writers summarised by Bireley: Giovanni Botero, Justus Lipsius, Carlo Scribani, Adam Contzen, Pedro de Ribadeneira, and Diego de Saavedra Fajardo. These authors criticized Machiavelli, but also followed him in many ways. They accepted the need for a prince to be concerned with reputation, and even a need for cunning and deceit, but compared to Machiavelli, and like later modernist writers, they emphasized economic progress much more than the riskier ventures of war. These authors tended to cite Tacitus as their source for realist political advice, rather than Machiavelli, and this pretence came to be known as " Tacitism ". "Black tacitism" was in support of princely rule, but "red tacitism" arguing the case for republics, more in the original spirit of Machiavelli himself, became increasingly important.

Modern materialist philosophy developed in the 16th, 17th and 18th centuries, starting in the generations after Machiavelli. Modern political philosophy tended to be republican, but as with the Catholic authors, Machiavelli's realism and encouragement of innovation to try to control one's own fortune were more accepted than his emphasis upon war and factional violence. Not only was innovative economics and politics a result, but also modern science, leading some commentators to say that the 18th century Enlightenment involved a "humanitarian" moderating of Machiavellianism.

The importance of Machiavelli's influence is notable in many important figures in this endeavour, for example Bodin, Francis Bacon, Algernon Sidney, Harrington, John Milton, Spinoza, Rousseau, Hume, Edward Gibbon, and Adam Smith. Although he was not always mentioned by name as an inspiration, due to his controversy, he is also thought to have been an influence for other major philosophers, such as Montaigne, Descartes, Hobbes, Locke and Montesquieu. Jean-Jacques Rousseau, who is associated with very different political ideas, viewed Machiavelli's work as a satirical piece in which Machiavelli exposes the faults of a one-man rule rather than exalting amorality.

In the seventeenth century it was in England that Machiavelli's ideas were most substantially developed and adapted, and that republicanism came once more to life; and out of seventeenth-century English republicanism there were to emerge in the next century not only a theme of English political and historical reflection – of the writings of the Bolingbroke circle and of Gibbon and of early parliamentary radicals – but a stimulus to the Enlightenment in Scotland, on the Continent, and in America.

Scholars have argued that Machiavelli was a major indirect and direct influence upon the political thinking of the Founding Fathers of the United States due to his overwhelming favouritism of republicanism and the republican type of government. According to John McCormick, it is still very much debatable whether or not Machiavelli was "an advisor of tyranny or partisan of liberty." Benjamin Franklin, James Madison and Thomas Jefferson followed Machiavelli's republicanism when they opposed what they saw as the emerging aristocracy that they feared Alexander Hamilton was creating with the Federalist Party. Hamilton learned from Machiavelli about the importance of foreign policy for domestic policy, but may have broken from him regarding how rapacious a republic needed to be in order to survive. George Washington was less influenced by Machiavelli.

The Founding Father who perhaps most studied and valued Machiavelli as a political philosopher was John Adams, who profusely commented on the Italian's thought in his work, A Defence of the Constitutions of Government of the United States of America. In this work, John Adams praised Machiavelli, with Algernon Sidney and Montesquieu, as a philosophic defender of mixed government. For Adams, Machiavelli restored empirical reason to politics, while his analysis of factions was commendable. Adams likewise agreed with the Florentine that human nature was immutable and driven by passions. He also accepted Machiavelli's belief that all societies were subject to cyclical periods of growth and decay. For Adams, Machiavelli lacked only a clear understanding of the institutions necessary for good government.
