Sparta was called an oligarchy because the ruling power was in the hands of a few people. The power was in the hands of the Council of Elders, which consisted of 30 men. Two of them were kings who inherited their power. And the other 28 were selected by an assembly. The people in the Council of Elders had to be at least 60 years of age. The Council of Elders were allowed to decide on new laws, and new changes.
Spartans got the goods they needed for everyday life by farming and conquering other people. Sparta didn't have enough land to feed all it's people, so Spartans took the land the needed from neighbors. And turned them into slaves or helots. They also used non-citizens called perioiki. The perioiki made red cloaks fro soldiers, iron tools like knifes and spear, and hey also traded with other city-states fro goods that Sparta did not have. Sparta used iron bars as money. So not many people liked trading with Sparta.
