Answer:
Jewish history is very old and dynamic, tracing back to over 3,000 years.
A common theme in Jewish history has been the persecution that has been suffered by the Jewish people.
The Jewish people have often hold their ancestral homeland: Israel, but they have also been expelled from these lands several times.
Jewish history is also the history of the Jewish diaspora: for centuries, there have been Jews living all over Europe and the Middle East, even in other areas.
Finally, Jewish history also includes the history of the Holocaust, the genocide in which over 5 million Jews were killed during the Second World War.
For these reasons above, Jewish history shapes Jewish culture. It makes the Jewish people cohesive and protective of their own people, because of all the suffering they have been through.
