A unifying story for Jews is the Exodus. In it, Moses leads the Jewish people out of Egypt and into Israel. Also, God talks to Abraham and tells him to sacrifice his son, then stops him just before he does.
The main current event in Judaism is the Palestinian and Jewish war over who owns Israel. An important historic event for Jews was when they escaped from Hitler and when the Romans destroyed their original synagogue.
