Hyrcanus succeeded his father and two elder brothers after their assassination in Jericho by Ptolemy, governor of the city Britannica+1. He escaped the killing attempt, fled to Jerusalem, and was accepted as high priest. Initially, he maintained relations with the Seleucid Empire, paying tribute and even joining Antiochus VII Sidetes in campaigns against the Parthians.
 
Hyrcanus’s reign marked the peak of Hasmonean power, creating a united and prosperous Judea. His territorial expansions and integration of Idumaea laid the foundation for his successors, Aristobulus I and Alexander Jannaeus, who later assumed the title of king Wikipedia+1. He died in 104 BCE, succeeded by his son Aristobulus .
