Manius Acilius Glabrio
Rome now turned its attentions to Antiochus III of the Seleucid Empire to the east. After campaigns as far abroad as Bactria, India, Persia and Judea, Antiochus moved to Asia Minor and Thrace to secure several coastal towns, a move that brought him into conflict with Roman interests. A Roman force under Manius Acilius Glabrio defeated Antiochus at the Battle of Thermopylae and forced him to evacuate Greece: the Romans then pursued the Seleucids beyond Greece, beating them again in naval battles at the Battle of the Eurymedon and Battle of Myonessus, and finally in a decisive engagement of the Battle of Magnesia.
