Niccolò Machiavelli was an Italian Renaissance diplomat, philosopher, and writer widely regarded as the father of modern political science. He established his authority through fourteen years of service as a high-ranking official in the Florentine Republic, where he managed diplomatic missions and military strategy. His seminal work, The Prince, revolutionized political philosophy by prioritizing pragmatism and realpolitik over idealism, providing a blueprint for statecraft that remains essential to the study of power and leadership.
