What are similarities and differences between Athens and Sparta's government?

Athens had 2 kings, one to rule the government, and one for domestic purposes and helping people. Sparta had Helots, which were slaves, and guards that would randomly kill one of the helots to show that that is what will happen if you run away. Athens and Sparta were both Democratic. But Athens was more of a free democracy. Citizens (males only) would put white or black rocks into a jar and thats how they would vote.

Hope this helps!
