Hello Valens,
You might find the Macedonian Wars interesting, were a vigorous struggle was maintained with the Achaean League and with Macedon until the Romans, after the conclusion of their war with Philip V sent an army into Laconia under T. Quinctius Flamininus.
Sparta was forced in 192 BC by Philopoenien to enroll itself as a member of the Achaean League under a phil-Achaean aristocracy.Again and again the relations between the Spartans and the Achaean League formed the occasion of discussions in the Roman senate or of the despatch of Roman embassies to Greece, but no decisive intervention took place until a fresh dispute about the position of Sparta in the league led to a decision by the Romans that Sparta, Corinth, Argos, Arcadian Orchomenus and Heraclea on Oeta should be severed from it. This resulted in an open breach between the league and Rome, and eventually, in 146 BC, after the sack of Corinth, in the dissolution of the league and the annexation of Greece to the Roman province of Macedonia.
