The Prince

Niccolò Machiavelli , or more formally Niccolò di Bernardo dei Machiavelli, was an Italian Renaissance historian, politician, diplomat, philosopher, humanist, and writer. He has often been called the founder of modern political science. He was for many years a senior official in the Florentine Republic, with responsibilities in diplomatic and military affairs. He also wrote comedies, carnival songs, and poetry. His personal correspondence is renowned in the Italian language. He was secretary to the Second Chancery of the Republic of Florence from 1498 to 1512, when the Medici were out of power. He wrote his most renowned work The Prince (Il Principe) in 1513.
"The Prince" is a reference about political philosophy that has influenced our modern society, like "The Art of War" by Sun Tzu (Also by Niccolò Machiavelli), "The Communist Manifesto" by Karl Marx and Friedrich Engels.
