Who invented the exile method of pottery? What contribution did he make to the development of democracy in Athens?

Cristini

He initiated the exile law of pottery tablets, which greatly weakened the rule of nobles, and created the "meeting of 500 people" and the "Committee of Ten Generals", which divided Athens into ten parts and selected 50 people from each area to participate in the "meeting of 500 people" by drawing lots, thus strengthening fairness.
