First, to decrease the power of the aristocrats, he established four new classes based on wealth, not family.
The higher a man’s class, the more government jobs he was qualified for.
Men from the laborer class were not qualified for any government jobs.
Men from all classes could participate in the ekklesia (assembly), which was responsible for passing laws.
Solon also established the boule (council of 400), which was responsible for the day-to- day governing of the polis and setting the ekklesia’s agenda.
Men from the top three classes could serve in the boule.
Solon also canceled debts, freed the enslaved citizens, and outlawed debt slavery.
