The Sadducees were moved to petition the queen for protection against the ruling party.
Salome Alexandra, who desired to avoid all party conflict, removed the Sadducees from Jerusalem, assigning certain fortified towns for their residence.

Salome Alexandra increased the size of the army and carefully provisioned the numerous fortified places so that neighbouring monarchs were duly impressed by the number of protected towns and castles which bordered the Judean frontier.
As well, she did not abstain from actual warfare; she sent her son Aristobulus with an army to besiege Damascus, then beleaguered by Ptolemy Menneus.
The expedition reportedly achieved little.

The last days of Salome Alexandra's reign were tumultuous.
Her son, Aristobulus, endeavoured to seize the government, and succeeded her after her death.
