The ideology and principles of Satmar reflect Yoel Teitelbaum's adherence to the Hungarian ultra-Orthodox school of thought (similar to, but also fundamentally different from, "Ultra-Orthodox Judaism"). This school was founded by Rabbi Hillel Lichtenstein and his son-in-law Akiva Yosef Schlesinger in the 1860s, on the eve of the Schism in Hungarian Jewry. Faced with rapid acculturation and a decline in religious observance, Lichtenstein preached utter rejection of modernity, widely applying the words of his teacher, Moses Sofer: "All that is new is forbidden by the Torah." Schlesinger accorded Yiddish and traditional Jewish garb a religious status, idealizing them as a means of separation from the outside world.
