Happy Birthday: Niccolò di Bernardo dei Machiavelli (3 May 1469 – 21 June 1527) was a Florentine diplomat, author, philosopher, and historian who lived during the Italian Renaissance. He is best known for his political treatise The Prince (Il Principe), written around 1513 but not published until 1532, five years after his death. He has often been called the father of modern political philosophy and political science.

For many years he served as a senior official in the Florentine Republic with responsibilities in diplomatic and military affairs. He wrote comedies, carnival songs, and poetry. His personal correspondence is also important to historians and scholars of Italian correspondence. He worked as secretary to the second chancery of the Republic of Florence from 1498 to 1512, when the Medici were out of power.

After his death Machiavelli's name came to evoke unscrupulous acts of the sort he advised most famously in his work, The Prince. He concerned himself with the ways a ruler could survive in politics, and knew those who flourished engaged in deception, treachery, and crime. He advised rulers to engage in evil when political necessity requires it, at one point stating that successful founders and reformers of governments should be excused for killing other leaders who would oppose them. Machiavelli's Prince has been surrounded by controversy since it was published. Some consider it to be a straightforward description of political reality. Many view The Prince as a manual, teaching would-be tyrants how they should seize and maintain power. Even into recent times, some scholars, such as Leo Strauss, have restated the traditional opinion that Machiavelli was a "teacher of evil".
