The Roman-Syrian War (192 BC - 188 BC), also known as War of Antiochus or Syrian War, was a military conflict between two coalitions led by the Roman Republic and the Seleucid Empire under Antiochus the Great. The fighting took place in Greece, the Aegean Sea and Asia Minor.
The war was the consequence of a "cold war" between both powers, which had started already in 196 BC. In this period Romans and Seleucids had tried to settle spheres of influence by making alliances with the Greek minor powers.
The fighting ended with a clear victory of the Romans. In the Treaty of Apamea the Seleucids were forced to give up Asia Minor, which fell to roman allies. As a main result of the war the Roman Empire gained the hegemony over Greece and became the only remaining major power around the Mediterranean Sea.
