The First Macedonian War (214 BC - 205 BC) was fought by Rome, allied (after 211 BC) with the Aetolian League and Attalus I of Pergamon, against Philip V of Macedon, contemporaneously with the Second Punic War against Carthage. There were no decisive engagements, and the war ended in a stalemate.
During the war, Macedon attempted to gain control over parts of Illyria and Greece, but without success. It is commonly thought that these skirmishes in the east prevented Macedon from aiding the Carthaginian general Hannibal in the war with Rome.
