When did judaism begin and who was the founder?

Answer 1

Abraham was the founder of Judaism. He made the eternal covenant with G-d; G-d promised to protect Abraham and his descendants, and to bless them and make 'great nations' from them. In return, the Jews must stay loyal to the one true G-d of Israel. Abraham was technically a Hebrew. The 'official' start of Judaism, was some time later, when Moses and the Israelites received the Torah from G-d at Mt Sinai. They then went forward as the Jewish family, the Jewish religion and the Jewish nation. -----------------------------------------------------------------------------------------------------

Answer 2

Tradition holds that Abraham founded the Jewish religion in Israel, about 2000 BCE, but no exact date is known.

There is archaeological evidence for the Israelites (The ancestors of the Jews) as far back as 1600 BCE.

Answer 3

Abraham. He lived 3800 years ago.
