A mora was an ancient Spartan military unit of about a sixth of the army, at approx. 600 men by modern estimates, although Xenophon places it at 6000. Either way, it was the largest tactical unit in Sparta if not all Greece and was often the only force sent out on campaign. A mora was composed of hoplites, men armed with spears, swords and aspis or hoplon (the word from which the soldier gets his name) and armoured in a curaiss, greaves and a Corinthian Helm. The unit was led by a Polemarch, the third (or arguably second) highest rank in Spartan heirachy, the higher being King, and possibly naval commander. However, sometimes there was a higher rank, that of Strategos, most famously held by Lysander. During the time of pure Phalanx combat in Greece, the mora was a very difficult obstacle for a commander to negotiate. However, Iphicrates of Athens used a small, elite group of Peltasts to destroy one. This proved the mora was defeatable, but also mortalised the Spartans, and so may have led to the Theban War which saw the collapse of Sparta.
