Sparta in popular culture is seen as the creme of the crop for ancient Greek armies and while no doubt that was true for some time, they were eventually beaten and broken by the late 300s and were later conquered by the Romans.

Could Sparta ever achieve a true hegemony over Greece like Alexander did? If so, how? Or was their Soldier/Citizen/Helot system a weight that would inevitably drag them into obscurity?
