Final answer:
Sparta was ruled as an oligarchy, while Athens was ruled as a democracy during ancient times.
Step-by-step explanation:
Sparta
During ancient times, Sparta was ruled as an oligarchy. It had an aristocratic monarchy, with two kings who ruled over councils of citizens. Under the kings, there was a smaller council that issued laws, and a large council made up of all Spartan males over 30 who approved or rejected the proposed laws.
Athens
Athens, on the other hand, was ruled as a democracy during ancient times. It developed into a militarily powerful democratic state in which all adult male citizens could participate in government. However, it's important to note that not all individuals were considered citizens, and the participation in government was limited to adult males.
