Shalom. Who are the Hellenized Jews, and what do they do?

Hellenized Jews were those who, during the time of the Greek Hellenists about 2,200 years ago, were influenced and assimilated to various extents to leave Jewish traditions and copy various Hellenist customs. The Maccabees in the story of Chanuka, were the ones who stood up against them and fought to remove the Hellenist influence from the Land of Israel.
