Hasmonean dynasty
After defeating the Seleucid forces, Judas Maccabaeus's nephew John Hyrcanus established a new monarchy in the form of the priestly Hasmonean dynasty in 152 BCE, thus establishing priests as political as well as religious authorities. Although the Hasmoneans were considered heroes for resisting the Seleucids, their reign lacked the legitimacy conferred by descent from the Davidic dynasty of the First Temple era.
