Titus Quinctius Flamininus
It was this point that Achaea switched her alliance with Macedon to support Rome. As Achaea was Sparta's main rival, Nabis leaned towards Macedonia. It was getting increasingly difficult for Macedonia to hold Argos, so Philip V of Macedon decided to give Argos to Sparta which increased tension with the Achaean League. Nonetheless, he was careful not to violate the letter of his alliance with Rome. After the conclusion of the wars with Philip V, Sparta's control of Argos contradicted the official Roman policy of freedom to the Greeks and Titus Quinctius Flamininus organized a large army with which he invaded Laconia and laid siege to Sparta.
