Judaism is one of the old religions from which religions like Christianity emerged from. Between 1900-1700 BCE, it was Abraham, widely known as a man of faith, who made covenant with God thus turning out to be a patriarch.
Similarly, Moses is strongly linked with the advent of Judaism following his call to deliver Israelites of Egypt. So in the process, people developed knowledge and faith in one superior God. Judaism is mainly based in the Near East. In 70A.D, the Jerusalem church was demolished thus leading to the spreading of the Jews and their Judaism religion in various regions within the East.
Tracing it from Biblical times, Judaism was considered to comprise of twelve tribes. These were Benjamin, Reuben, Dan, Naftali, Manasseh, Simeon, Issachar, Gad, Judah, Ephraim, Zebulun and Asher. Similarly, the term Jew was derived from Judah’s kingdom comprising Judah’s and Benjamin’s tribes.
