Beth Hamedrash was the prototypical American synagogue for early immigrant Eastern European Jews, who began entering the United States in large numbers only in the 1870s. They found the synagogues of the German Jewish immigrants who preceded them to be unfamiliar, both religiously and culturally. Russian Jews in particular had been more excluded from Russian society than were German Jews from German society, for both linguistic and social reasons. Unlike German Jews, the Jews who founded Beth Hamedrash viewed both religion and the synagogue as central to their lives. They attempted to re-create in Beth Hamedrash the kind of synagogue they had belonged to in Europe.
