Settlements > Sparta
Sparta never fully recovered from the losses that the Spartans suffered at Leuctra in 371 BC and the subsequent helot revolts. Nonetheless, it was able to continue as a regional power for over two centuries. Neither Philip II nor his son Alexander the Great attempted to conquer 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 enter Laconia, I will raze Sparta", the Spartans responded with the single, terse reply: αἴκα, "if".
When Philip created the league of the Greeks 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".
During Alexander's campaigns in the east, the Spartan king, Agis III sent a force to Crete in 333 BC with the aim of securing the island for Sparta. 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 to join.
