Niccolò Machiavelli was an Italian Renaissance historian, politician, diplomat, philosopher and writer. He is considered the founder of modern political science. Machiavelli served as a Florentine official and wrote two of his most famous works, The Prince and Discourses on Livy, to advise rulers on how to maintain power. He took a pragmatic approach, arguing rulers should prioritize strengthening the state over traditional Christian ethics and morality. Machiavelli believed a strong, centralized state led by a powerful prince was needed to unite Italy's divided regions and overcome corruption. His writings had a profound impact on modern political thought by separating politics from religion and ethics.
