Why does Plato reject democracy?

Plato rejects democracy because he believed that it was an unstable form of government that could easily lead to tyranny. He argued that democracy could be manipulated by demagogues who appeal to the emotions of the people rather than reason, resulting in a society ruled by unqualified leaders. Plato believed that a philosopher-king, guided by wisdom and reason, was the ideal ruler for a just and harmonious society.
