WThe Aetolian War was fought between the Romans and their Achaean and Macedonian allies and the Aetolian League and their allies, the kingdom of Athamania. The Aetolians had invited Antiochus III the Great to Greece, who after his defeat by the Romans had returned to Asia. This left the Aetolians and the Athamanians without any allies. With Antiochus out of Europe the Romans and their allies attacked the Aetolians. After a year of fighting the Aetolians were defeated and forced to pay 1,000 talents of silver to the Romans.
WThe Cleomenean War was fought by Sparta and its ally, Elis, against the Achaean League and Macedon. The war ended in a Macedonian and Achaean victory.
WThe Cretan War was fought by King Philip V of Macedon, the Aetolian League, many Cretan cities and Spartan pirates against the forces of Rhodes and later Attalus I of Pergamum, Byzantium, Cyzicus, Athens, and Knossos.
WFrom their new bases in northern Illyria and Pannonia, the Gallic invasions climaxed in the early 3rd century BC, with the invasion of Greece. The 279 BC invasion of Greece proper was preceded by a series of other military campaigns waged in the southern Balkans and against the kingdom of Macedonia, favoured by the state of confusion ensuing from the disputed succession after Alexander the Great's death. A part of the invasion crossed over to Anatolia and eventually settled in the area that came to be named after them, Galatia.
WThe Macedonian Wars were a series of conflicts fought by the Roman Republic and its Greek allies in the eastern Mediterranean against several different major Greek kingdoms. They resulted in Roman control or influence over the eastern Mediterranean basin, in addition to their hegemony in the western Mediterranean after the Punic Wars. Traditionally, the "Macedonian Wars" include the four wars with Macedonia, in addition to one war with the Seleucid Empire, and a final minor war with the Achaean League. The most significant war was fought with the Seleucid Empire, while the war with Macedonia was the second, and both of these wars effectively marked the end of these empires as major world powers, even though neither of them led immediately to overt Roman domination. Four separate wars were fought against the weaker power, Macedonia, due to its geographic proximity to Rome, though the last two of these wars were against haphazard insurrections rather than powerful armies. Roman influence gradually dissolved Macedonian independence and digested it into what was becoming a leading global empire. The outcome of the war with the now-deteriorating Seleucid Empire was ultimately fatal to it as well, though the growing influence of Parthia and Pontus prevented any additional conflicts between it and Rome.
WPyrrhus' invasion of the Peloponnese in 272 BC was an invasion of south Greece by Pyrrhus, King of Epirus. He was opposed by Macedon and a coalition of Greek city-states (poleis), most notably Sparta. The war ended in a joint victory by Macedonia and Sparta.
WThe Seleucid War, also known as the War of Antiochos or the Syrian War, was a military conflict between two coalitions led by the Roman Republic and the Seleucid Empire. The fighting took place in modern day southern Greece, the Aegean Sea and Asia Minor.
WThe Social War, also War of the Allies and the Aetolian War, was fought from 220 BC to 217 BC between the Hellenic League under Philip V of Macedon and the Aetolian League, Sparta and Elis. It was ended with the Peace of Naupactus.
WThe Laconian War of 195 BC was fought between the Greek city-state of Sparta and a coalition composed of Rome, the Achaean League, Pergamum, Rhodes, and Macedon.
