What did Sparta trade?

Answer 1

Nothing. It's hard for textbooks to say anything nice about the Spartans. Take up any world history textbook and read; you'll find that the Spartans were "an armed camp," "brutal," "culturally stagnant," "economically stagnant," "politically stagnant," and other fun things. The reality, of course, lies somewhere behind the value judgements.

The single, overwhelming fact of Spartan history is the Messenean War. In the eighth century BC, Sparta, like all her neighbors, was a monarchy with a limited oligarchy. In 725, however, needing land to feed a dramatically growing population, the Spartans marched over the Taygetus mountains and annexed all the territory of their neighbor, Messenia. The Messenians occupied a fertile plain and the Spartans found themselves with more than enough land to support themselves and their newly conquered people. However, like all conquered people, the Messenians did not appreciate the loss of their independence. With the help of the city-state of Argos, the Messenians revolted in 640 BC. This was no ordinary revolt, for not only did the Messenians almost win, they almost destroyed Sparta itself.
