The question calls to my mind an anecdote, only tangentially related, that
chills me and which I must share:
During one of his infrequent visits to the US, the Dalai Lama requested
a meeting with Elie Wiesel, and asked: Your people were exiled for two
thousand years and survived. Please help me understand what sustained
you. My people have been recently sent into exile, and it will be a long one.
Told by Elie Wiesel.
Judaism started about 4000 years ago in the Middle East region. A Hebrew named Abraham is credited with promoting and spreading Judaism.
Tradition holds that Judaism was founded by Abraham in Israel, about 4000 years ago. Judaism has undergone many transformations since that time. The type of Judaism practiced today, called "Rabbinic Judaism" has been around almost 2000 years.
Unlike Christianity, Judaism is not centralised and does not have the equivalent to "The Church".

The social culture of Judaism has been in constant change since the beginning of the religion about 4000 years ago. If you could specify a certain era, it would be helpful.
According to our tradition, it lasted from Abraham (3800 years ago) until the sealing of the Tanakh's canon (2350 years ago).
