Antiochus VI Dionysus

Antiochus VI Dionysus (c. 148–142/1 BC), king of the Hellenistic Seleucid kingdom, was the son of Alexander Balas and Cleopatra Thea, daughter of Ptolemy VI of Egypt.

Biography
Antiochus VI did not actually rule. Either already in 145 or in early 144 BC he was nominated by the general Diodotus Tryphon as heir to the throne in opposition to Demetrius II, and remained the general's tool. In c. 142/141 BC, the young king died. While some ancient authors make Diodotus Tryphon responsible for the death of the king, others write that he died during a surgery.
