Judaization (Hebrew: לְגַיֵּיר, translit. legayer) or Judaification is a process of cultural assimilation in which a person or a demographic group acquires Jewish cultural and religious beliefs and values.
It is the obverse of "de-Judaization", the process observed, for example, in Soviet Russia, where discriminatory practices against Jews gave momentum to their "de-Judaization".
Haredization refers to a late 20th- and early 21st-century phenomenon, in which urban and suburban areas of Israel, such as Beit Shemesh, become demographically and politically dominated by Haredim at the expense of non-Haredim (including religious Zionists and Hilonim). The trend is often the subject of protests in various Israeli cities.
