Third Macedonian War
After the Third Macedonian War, Rome abolished the Macedonian monarchy and divided Macedon into four client republics, called "merides", with capitals located at Amphipolis, Thessalonica, Pella, and Pelagonia, which were members of a federal league, the League of the Macedonians. Numismatic evidence indicates that the cult of Roma was introduced at this time, being depicted on coins of Amphipolis, Pella, and Thessalonica in this period.
