Niccolo Machiavelli was an Italian diplomat, philosopher, and writer during the Renaissance period. He held several government positions in Florence, where he gained experience in politics and diplomacy. Machiavelli is considered the founder of modern political science due to works like The Prince, where he analyzed power and politics in a pragmatic way, separate from religious and moral considerations. He viewed human nature as selfish and focused on how rulers could maintain their power through both fear and popularity. While controversial, Machiavelli's realist approach to politics has remained influential to the present day.
