Roman civil wars
After the death of Julius Caesar, for a brief period Iamblichus I supported the Roman Governor of Syria who was one of Julius Caesar's assassins. In the period of the Roman civil wars, Iamblichus I supported the Roman triumvir Octavian. Iamblichus I became suspect to Roman Triumvir Mark Antony. Antony encouraged Iamblichus I's brother Alexander, to usurp his brother's throne and had Iamblichus I executed. Octavian, after defeating Antony and reorganising the Eastern Roman provinces, had Alexander executed for treason in 31 BC. From 30 BC until 20 BC, the Emesene Kingdom was dissolved and became an autonomous community free of dynastic rule though under the supervision of the Roman governor of Syria.
