The main prophet of Judaism isn't proclaimed as their leader is. The leader of the Jewish people is God and only one God. The religion was founded in the Middle East. It isn't exactly known where but Israel definitely is the most populated region of Jewish people. Judaism has a connection to Christianity in that both religions obey one God. Christianity is lead by Jesus who is their savior, but is God on earth, so still considered one God.
