This Is Sparta
The physical city of Sparta had now developed and was in its early stages of building on the social structures that would come to define the Spartans themselves. It wouldn’t be a conscious decision, but like most societies, consequences of their past actions and behaviours.
Like most founding stories of cities and institutions, the Spartans also place the beginnings of their constitution on a mystical, shadowy figure named Lycurgus. He would be the equivalent of their old wise man bringing stability to a troubled society. Though, trying to pin point his actual existence in the historical record has proved elusive.
With the Spartans crediting Lycurgus with the foundations of their constitution, some very unique institutions would develop. Spartan society would rest upon a duel kingship, but with a council of elders instrumental in leading the state also. An education system was developed that would produce the required warriors to protect their way of life. The individual was not of importance, but how they could best serve the Polis.
As the Spartans approached the Classical Age, they were focused on spreading their influence throughout the Peloponnese. Not only were they using strength of arms but they would also engage in diplomacy. This combination would see them being recognised within Greece and internationally as the leading power in Greece. Though, they had to always remain vigilant against the threat within their own boarders, the potential of a Helot revolt from breaking out.
