Solon, a businessman of aristocratic lineage, to the supreme archonship. He devaluated the currency, thereby easing the burden of all debtors (though he himself was a creditor); he reduced all personal debts, and ended imprisonment for debt; he canceled arrears for taxes and mortgage interest; he established a graduated income tax that made the rich pay at a rate twelve times that required of the poor; he reorganized the courts on a more popular basis; and he arranged that the sons of those who had died in war for Athens should be brought up and educated at the government’s expense.
