I thoroughly enjoy your lectures, thank you.
With regards to the backdrop of the Persian Wars & Athens’ “alliance” with Darius b/c of tensions with Sparta.
Were the Spartans mercenary-like when it came to Athens, fighting on behalf of whomever was in power (e.g., with Cleisthenes then against him in 507)?
Other sources I’ve consulted site Sparta’s concern over Athenian power and/or spreading of democracy.
Any clarification/links are appreciated!
