The study of political science has evolved over centuries, with contributions from numerous thinkers. It's not attributable to a single author. However, some key figures laid the groundwork for the discipline:

• Plato: His work, The Republic, explored ideal forms of government and justice.
• Aristotle: Often considered the "father of political science," he systematically analyzed different political systems in his book, Politics. Britannica - Aristotle
• Niccolò Machiavelli: His book, The Prince, offered a pragmatic (and often controversial) view of power and statecraft. Britannica - Niccolo Machiavelli

These are just a few of the many influential figures who have shaped the field of political science. Modern political science draws upon a wide range of perspectives and methodologies.
