Some scholars believe that Modern Orthodoxy arose from the religious and social realities of Western European Jewry. While most Jews consider Modern Orthodoxy traditional today, some (the hareidi and hasidic groups) within the Orthodox community consider some elements to be of questionable validity. The neo-Orthodox movement holds that Hirsch's views are not accurately followed by Modern Orthodoxy. [See Torah im Derech Eretz and Torah Umadda "Relationship with Torah im Derech Eretz" for a more extensive listing.]

Who did the modern orthodoxy arise from?
