The earliest classification of constitutions was the work of Aristotle. Aristotle was a Greek philosopher who lived in the 4th century BCE. He was a student of Plato and the tutor of Alexander the Great. Aristotle wrote a book called "Politics" where he analyzed different types of constitutions that existed in his time. He classified constitutions based on the number of rulers and the purpose of the government. According to Aristotle, there were three main types of constitutions: monarchy, aristocracy, and polity. Monarchy is a government ruled by one person, aristocracy is a government ruled by a few people, and polity is a government ruled by many people. Aristotle also identified three corrupt forms of these constitutions: tyranny (corrupt monarchy), oligarchy (corrupt aristocracy), and democracy (corrupt polity). Aristotle's classification of constitutions has been very influential throughout history and is still studied today. It laid the groundwork for modern political science and the study of constitutions.
