Aristotle's main point of view in studying regime theory is

Aristotle (384-322 BC) was an ancient Greek philosopher. His regime theory emphasized the advantages and disadvantages of different regimes and their evolution. He believes that regimes can be divided into two categories: justice and injustice. A just regime includes monarchy, aristocracy and middle class, while an unjust regime is the corresponding form of corruption. He believes that the most ideal regime is the golden mean, that is, the mixed regime of monarchy, aristocracy and democracy, in order to balance the power of all classes and avoid political corruption. Aristotle pays attention to the stability of political power and thinks that the health of political power depends on the virtue and education of citizens. His regime theory has a far-reaching influence on the history of western political thought, affecting later political thinkers and system design.
