Commencement of the reign of Shlom–Tzion (Salome Alexandra), the only Jewish queen ever over Judea.
During her nine–year reign, Salome’s son Hyrcanus II is named her successor and installed as high priest. However, power apparently resided in the hands of his Machiavellian adviser, Antipater the Idumaean. In sync with the Pharisees (Shimon ben Shetach, the head of the Pharisees, is said to have been Salome’s brother) Salome reorganizes the Sanhedrin according to their (Pharisee/Sanhedrin) wishes.
This effectively re–morphs the Sanhedrin from a quasi house of lords (of the aristocracy) which it had evolved into, back into a “supreme court” for the adjudication of religious matters, which was its very original mandate.
Salome was the last ruler to die as the head of a fully independent Jewish state in Israel until the formation of the modern state of Israel in 1948, 2015 years later.
