What are three classifications of government according to Aristotle?

According to Aristotle, governments can be classified into three main categories based on who rules and for whose benefit: monarchy, aristocracy, and polity. Monarchy is the rule of one for the common good, while tyranny is its corrupt form, serving only the ruler's interests. Aristocracy involves a few ruling for the benefit of the community, with its corrupt counterpart being oligarchy, where the few rule for their own benefit. Finally, polity represents the rule of many in favor of the common good, contrasting with democracy, which Aristotle viewed as a corrupt form where the majority seeks their own advantage.
