Roman–Seleucid War in the context of "Cold war (general term)"

The Battle of Thermopylae took place on 24 April 191 BC. It was fought as part of the Roman–Seleucid War, pitting forces of the Roman Republic led by the consul Manius Acilius Glabrio against a Seleucid-Aetolian army of Antiochus III the Great.

When the main bodies of the armies initially clashed at the Thermopylae pass, the Seleucids managed to hold their ground, repulsing multiple Roman assaults. However, a small Roman force under Marcus Porcius Cato managed to outflank the Seleucids from the hillside after surprising the Aetolian garrison of Fort Callidromus. The Seleucids panicked and broke ranks, leading to the destruction of their force. Antiochus managed to escape the battlefield with his cavalry, departing mainland Greece soon afterwards.

The Battle of Magnesia took place in either December 190 or January 189 BC. It was fought as part of the Roman–Seleucid War, pitting forces of the Roman Republic led by the consul Lucius Cornelius Scipio Asiaticus and the allied Kingdom of Pergamon under Eumenes II against a Seleucid army of Antiochus III the Great. The two armies initially camped northeast of Magnesia ad Sipylum in Asia Minor (modern-day Manisa, Turkey), attempting to provoke each other into a battle on favorable terrain for several days.

When the battle finally began, Eumenes managed to throw the Seleucid left flank into disarray. While Antiochus' cavalry overpowered his adversaries on the right flank of the battlefield, his army's center collapsed before he could reinforce it. Modern estimates give 10,000 dead for the Seleucids and 5,000 killed for the Romans. The battle resulted in a decisive Roman-Pergamene victory, which led to the Treaty of Apamea that ended Seleucid domination in Asia Minor.

The Treaty of Apamea was a peace treaty conducted in 188 BC between the Roman Republic and Antiochus III, ruler of the Seleucid Empire. It ended the Roman–Seleucid War. The treaty took place after Roman victories at the Battle of Thermopylae (in 191 BC), the Battle of Magnesia (in 190 BC), and after Roman and Rhodian naval victories over the Seleucid navy.

Publius Cornelius Scipio Africanus (/ˈskɪp.i.oʊ/, /ˈsɪp-/, Latin: [ˈskiːpioː]; 236/235–c. 183 BC) was a Roman general and statesman who was one of the main architects of Rome's victory against Carthage in the Second Punic War. Often regarded as one of the greatest military commanders and strategists of all time, his greatest military achievement was the defeat of Hannibal at the Battle of Zama in 202 BC. This victory in Africa earned him the honorific epithet Africanus, literally meaning 'the African', but meant to be understood as a conqueror of Africa.

Scipio's conquest of Carthaginian Iberia culminated in the Battle of Ilipa in 206 BC against Hannibal's brother Mago Barca. Although considered a hero by the Roman people, primarily for his victories against Carthage, Scipio had many opponents, especially Cato the Elder, who hated him deeply. In 187 BC, he was tried in a show trial alongside his brother for bribes they supposedly received from the Seleucid king Antiochus III during the Roman–Seleucid War. Disillusioned by the ingratitude of his peers, Scipio left Rome and retired from public life at his villa in Liternum.
