What happened 145 AD

Chong of Han died.

Chong's young third cousin Emperor Zhi of Han became emperor of the Han dynasty, with Liang Na acting as regent.

Alexander Balas reigned until 145 BC when he was overthrown by Demetrius I's son, Demetrius II Nicator. Demetrius II proved unable to control the whole of the kingdom, however. While he ruled Babylonia and eastern Syria from Damascus, the remnants of Balas' supporters – first supporting Balas' son Antiochus VI, then the usurping general Diodotus Tryphon – held out in Antioch.

Philometor was killed in the Battle of Antioch.

In 145 BC, however, Aristarchus became caught up in a dynastic struggle in which he supported Ptolemy VII Neos Philopator as the ruler of Egypt.
