Alexander I Balas was promoted as a rival to the Seleukid king Demetrios I by a Attalos II of Pergamon, who had been alienated by Demetrios' hostility. Soon, Alexander gained the support of the Romans and the Ptolemaic kingdom, and successfully invaded Syria. After Demetrios was killed in battle, Alexander requested a marriage alliance with Ptolemy VI, which was granted. In 150 BC, a royal wedding was held with both kings in attendance, in which Alexander received the hand of Ptolemy's eldest daughter, Cleopatra Thea. This great event was widely promoted, and commemorated on this rare issue of Seleukid tetradrachms and bronze with the royal couple on the obverse, as well as on a Ptolemaic issue of gold staters with Cleopatra's portrait. The harmony between the empires was short-lived. After the Seleukid empire suffered massive defeats in the east to the Parthians and Elymaians, Demetrios II, son of Demetrios I, invaded Coele-Syria. As the Seleukids rallied to Demetrios, Ptolemy, recognizing Alexander's weakness, gave his support to the new king. After finally meeting Demetrios in battle, Alexander was defeated and fled to Arabia, where he was murdered.
