Macedonian Wars
The Roman Republic had developed close ties to the Achaean League through similar religious and military beliefs and a cooperation in the previous Macedonian Wars. But despite co-operation in the latter part of the third century and early second century, political problems in Achaea soon came to a head. Two factions began to emerge - one, championed by the Achaean statesmen Philopoemen and Lycortas, which called for Achaea to determine its own foreign policy according to its own law, and one, championed by figures like Aristaenus and Diophanes, who believed in yielding to Rome on all matters of foreign policy.
