Thank you! Before you examine what we've done so far, it's important to understand that while we're naming our project The Peloponnesian Wars, we're really covering the entirety of the 5th Century BCE while using that period for the bulk of our content. Therefore, figures and events from earlier and later periods (such as Leonidas and the earlier Greco-Persian Wars, and Xenophon and the later March of the Ten Thousand) will be referenced and included.
We're definitely trying to keep everything as true to fact as possible, though, and so far we're succeeding quite nicely. Thanks all for the responses!
