Simon's appointment was made possible by a consensus among the clergy, religious leaders, traditional aristocratic families and esteemed elders.[30] To emphasize popular legitimacy and support for his appointment, Simon established a grand tribunal which would later be known as the Great Sanhedrin. The Hasmonean leader was at once the high priest (despite not being thought to be of the Zadok family[31]), the supreme military leader as well as the Nasi of the Jews. For the first time, both religious and political leadership rested with one man.
