The Chassidus is named after Aharon Roth, who established a group in Satmar in the year 1921, which was characterized by far-reaching criteria for the worship of God. In 1928, Rabbi Roth immigrated to the Land of Israel. Because of the special importance he saw in reciting amen aloud, Roth changed the group's name in 1933 to "Shomer Emunim".
