Spartan laws are in many ways underrated, in that their vices are widely known, but not their main selling point; as far as I know, Sparta never had a civil war within its citizen class, which is more than can be said for most other Greek cities. Furthermore, it should be remembered that slaves formed a key strata of most Greek cities' social orders, and were more than happy to abandon the city that enslaved them for its enemies; Sparta was not unique in having its helot class. What I find interesting is that while some citizens always remained to guard against a helot uprising, the Spartans could usually make their citizen soldier class stretch farther by emphasizing their expertise as commanders and drillmasters; whole armies were built with just thirty Spartiates serving as officers, with the rank and file filled out with allies, mercenaries, and freed helots. Spartans were unique among Greek armies in training in formation drill and being able to maneuver; while their allies often resented it, being subject to military discipline absolutely made them more effective fighters. Sparta was also not the cultural desert people make it out to be; the prominence of Athens in the historiography is mostly due to a trick in sources; proportionately more Athenian sources survive than those of other Greek cities.
