In 1944, during the occupation of Hungary by Nazi Germany, Hungarian authorities forced the Jewish inhabitants into the Oradea ghetto before sending them to the Auschwitz concentration camp. Descendants of the pre-Holocaust hasidic rabbinate in Oradea established a synagogue in the Willowbrook area of Staten Island, New York City. The synagogue maintains both a traditional hasidic Nusach Sefard and a Nusach Ashkenaz service, the latter of which operates under the name Bais Medrash Igud Avreichim of Groisverdain (the Yiddish pronunciation of Grosswardein).
