a helot population that vastly outnumbered its citizens. The alarming decline of Spartan citizens was commented on by Aristotle. Hellenistic and Roman Sparta Sparta never fully recovered from its losses at Leuctra in 371 BC and the subsequent helot revolts. In 338, Philip II invaded and devastated much of Laconia, turning the Spartans out, though he did not seize Sparta itself. Even during its decline, Sparta never forgot its claim to be the "defender of Hellenism" and its Laconic wit. An anecdote has it that when Philip II sent a message to Sparta saying "If I invade Laconia, I shall turn you out.", the Spartans responded with the single, terse reply: , "if". When Philip created the League of Corinth on the pretext of unifying Greece against Persia, the Spartans chose not to join, since they had no interest in joining a pan-Greek expedition unless it were under Spartan leadership. Thus, upon defeating the Persians at the Battle of the Granicus, Alexander the Great sent to Athens 300 suits of Persian armour with the following inscription: "Alexander, son of Philip, and all the Greeks except the Spartans, give these offerings taken from the foreigners who live in Asia". Sparta continued to be one of the Peloponesian powers until its eventual loss of independence in 192 BC. During Alexander's campaigns in the east, the Spartan king Agis III sent a force to Crete in 333 BC to secure the island for the Persian interest. Agis next took command of allied Greek forces against Macedon, gaining early successes, before laying siege to Megalopolis in 331 BC. A large Macedonian army under general Antipater marched to its relief and defeated the Spartan-led force in a pitched battle. More than 5,300 of the Spartans and their allies were killed in battle, and 3,500 of Antipater's troops. Agis, now wounded and unable to stand, ordered his men to leave him behind to face the advancing Macedonian army so that he could buy them time to retreat. On his knees, the Spartan king slew several enemy soldiers before being finally killed by a javelin. Alexander was merciful, and he only forced the Spartans to join the League of Corinth, which they had previously refused. During the Punic Wars, Sparta was an ally of the Roman Republic. Spartan political independence was put to an end when it was eventually forced into the Achaean League after its defeat
