>Yes, but the same democracy in Athens had strict rules about voting participation, and about 35% of the population was enslaved.
Which is a historical accident, based on the norms of the era, and is beside the point.
After all, the same thing (slavery) was happening in every, or almost every, country at the time. The innovation is what they CHANGED, not what they maintained.
Coincidentally, about 300,000 people lived in Athens at the time, while it's estimated that only 30,000 people were eligible to vote.
