In Asia also this royal testament kindled a civil war.

Relying on the aversion of the Asiatics to the foreign rule which awaited them, Aristonicus, a natural son of Eumenes II, made his appearance in Leucae, a small seaport between Smyrna and Phocaea, as a pretender to the crown.
Phocaea and other towns joined him, but he was defeated at sea off Cyme by the Ephesians--who saw that a steady adherence to Rome was the only possible way of preserving their privileges--and was obliged to flee into the interior.

The movement was believed to have died away when he suddenly reappeared at the head of the new "citizens of the city of the sun,"(33) in other words, of the slaves whom he had called to freedom en masse, mastered the Lydian towns of Thyatira and Apollonis as well as a portion of the Attalic townships, and summoned bands of Thracian free-lances to join his standard.
The struggle was serious.

There were no Roman troops in Asia; the Asiatic free cities and the contingents of the client-princes of Bithynia, Paphlagonia, Cappadocia, Pontus, Armenia, could not withstand the pretender; he penetrated by force of arms into Colophon, Samos, and Myndus, and already ruled over almost all his father's kingdom, when at the close of 623 a Roman army landed in Asia.
Its commander, the consul and -pontifex maximus- Publius Licinius Crassus Mucianus, one of the wealthiest and at the same time one of the most cultivated men in Rome, equally distinguished as an orator and as a jurist, was about to besiege the pretender in Leucae, but during his preparations for that purpose allowed himself to be surprised and defeated by his too-much-underrated opponent, and was made a prisoner in person by a Thracian band.

But he did not allow such an enemy the triumph of exhibiting the Roman commander-in-chief as a captive; he provoked the barbarians, who had captured him without knowing who he was, to put him to death (beginning of 624), and the consular was only recognised when a corpse.
