The Pahlavi dynasty implemented modernizing reforms, which greatly improved the life of Jews. The influence of the Shi'a clergy was weakened, and the restrictions on Jews and other religious minorities were abolished. According to Charles Recknagel and Azam Gorgin of Radio Free Europe, during the reign of Reza Shah "the political and social conditions of the Jews changed fundamentally. Reza Shah prohibited mass conversion of Jews and eliminated the concept of uncleanness of non-Muslims. He allowed incorporation of modern Hebrew into the curriculum of Jewish schools and publication of Jewish newspapers. Jews were also allowed to hold government jobs. Reza Shah's ascent brought temporary relief to Jews. In the 1920s, Jewish schools were closed again. In the 1930s, "Reza Shah's pro-Nazi sympathies seriously threatened Iranian Jewry. There were no persecutions of the Jews, but, as with other minorities, anti-Jewish articles were published in the media. Unlike religiously motivated prejudice, anti-Jewish sentiments acquired an ethnonational character, a direct import from Germany."
