According to Aristotle, which form of government is most likely to devolve into tyranny when corrupted?

Aristotle considered democracy to be the form of government most likely to devolve into tyranny when corrupted. In his work "Politics," he argued that while democracy is a system of governance that allows for the participation of the broad citizenry, it can also lead to mob rule. In such cases, the majority could prioritize their interests over the common good, leading to instability and the potential for an individual or elite to seize power, ultimately resulting in tyranny. Aristotle highlighted that the best systems incorporate elements of both democracy and oligarchy but warned that pure forms of democracy might become vulnerable to the risk of corruption.
