Eastern Europe

The slow pace of modernization in Russia, Congress Poland and Romanian principalities delayed the crisis of traditional society for decades., Harsh discrimination and active persecution of Jews continued there until 1917. Old-style education in the heder and yeshiva remained the norm, retaining Hebrew as the language of the elite and Yiddish as the vernacular. The defining fault-line of Eastern European Jews was between the Hasidim and the Misnagdic reaction against them. Reform attempts by the Czar 's government all had little influence. School modernization under Max Lilienthal, the growth of rabbinical seminaries and the mandating to appoint clerks known as "official rabbis" all had little impact. Communal autonomy and the rabbinic courts' jurisdiction were abolished in 1844, but economic and social seclusion remained, ensuring the de facto authority of Jewish institutions and traditions. In 1880, only 21,308 Jewish pupils attended government schools, out of some 5 million Jews; In 1897, 97% of the 5.2 million Jews in the Pale of Settlement and Congress Poland spoke Yiddish their mother tongue, and only 26% were literate in Russian. Though the Eastern European Haskalah challenged the traditional establishment, it flourished from the 1820s until the 1890s. Unlike its western counterpart, it thrived despite ongoing acculturation. The leading rabbis maintained the concept of communal unity: in 1882, when an Orthodox party in Galicia appealed for the right of secession, the Netziv and other Russian rabbis forbade it for contradicting the idea of Israel's unity.

In the 1860s and 1870s, moderate maskilic rabbis like Yitzchak Yaacov Reines and Yechiel Michel Pines called for inclusion of secular studies in the heder s and yeshiva s, anticipating a communal disintegration as in the west. Instead they proposed a careful modernization, based on a consensus on the adaptation of halakha. Their initiative was thwarted by a combination of radical, secularist maskilim and leading conservative rabbis. This was highlighted during the battle that erupted after Moshe Leib Lilienblum 's 1868 call for a reconsideration of Talmudic strictures. Reines, Pines and their associates gradually formed the nucleus of Religious Zionism, while their conservative opponents adopted the epithet Haredim (generic term for the observant and the pious).

Jewish nationalism, particularly Zionism, with its nonobservant if not staunchly secular partisans, was the key question facing Eastern European traditionalists, although it was tangled with modernization. Salmon claimed that the future Zionists were: supportive of a national agenda; motivated by criticism of Jewish society; supportive of modernity; tolerant of nonobservance; and approving of traditional faith and practice. Their proto- Haredi opponents sharply rejected all he former positions and espoused staunch conservatism, which idealized existing norms. Any illusion that differences could be blanded and a united observant pro-Zionist front would be formed, were dashed between 1897 and 1899, as both the Eastern European nationalist intellectuals and Theodor Herzl himself revealed an uncompromising secularist agenda, forcing traditionalist leaders to pick sides. In 1900, the anti-Zionist pamphlet Or la-Yesharim, endorsed by many Russian and Polish rabbis, largely demarcated the lines between the proto- Haredi majority and the Mizrahi minority, and terminated dialogue; in 1911, when the 10th World Zionist Congress voted in favour of propagating non-religious cultural work and education, a large segment of the Mizrahi seceded and joined the anti-Zionists.

In 1907, Eastern European proto- Haredi elements formed the Knesseth Israel party, a modern framework created in recognition of the deficiencies of existing institutions. It dissipated within a year. German Neo-Orthodoxy, in the meantime, developed a keen interest in the traditional Jewish masses of Russia and Poland; if at the past they were considered primitive, a disillusionment with emancipation and enlightenment made many young assimilated German Orthodox youth embark on journeys to East European yeshivot, in search of authenticity. The German secessionists already possessed a platform of their own, the Freie Vereinigung für die Interessen des Orthodoxen Judentums, founded by Samson Raphael Hirsch in 1885. In 1912, two German FVIOJ leaders, Isaac Breuer and Jacob Rosenheim, managed to organize a meeting of 300 seceding Mizrahi, proto- Haredi and secessionist Neo-Orthodox delegate in Katowice, creating the Agudath Israel party. While the Germans were a tiny minority in comparison to the Eastern Europeans, their modern education made them a prominent elite in the new organization, which strove to provide a comprehensive response to world Jewry's challenges in a strictly observant spirit. The Agudah immediately formed its Council of Torah Sages as supreme rabbinic leadership body. Many ultra-traditionalist elements in Eastern Europe, like the Belz and Lubavitch Hasidim, refused to join, viewing the movement as a dangerous innovation; and the organized Orthodox in Hungary rejected it as well, especially after it did not affirm a commitment to communal secession in 1923.

In the Interwar period, sweeping secularization and acculturation deracinated old Jewish society in Eastern Europe. The October Revolution granted civil equality and imposed anti-religious persecutions, radically transforming Russian Jewry within a decade; the lifting of formal discrimination also strongly affected the Jews of independent Poland, Lithuania and other states. In the 1930s, it was estimated that no more than 20%–33% of Poland's Jews, the last stronghold of traditionalism where many were still living in rural and culturally-secluded communities, could be considered strictly observant. Only upon having become an embattled (though still quite large) minority, did the local traditionalists complete their transformation into Orthodox, albeit never as starkly as in Hungary or Germany. Eastern European Orthodoxy, whether Agudah or Mizrahi, always preferred cultural and educational independence to communal secession, and maintained strong ties and self-identification with the general Jewish public. Within its ranks, the 150-years-long struggle between Hasidim and Misnagdim was largely subsided; the latter were even dubbed henceforth as "Litvaks", as the anti-Hasidic component in their identity was marginalized. In the interwar period, Rabbi Yisrael Meir Kagan emerged as the popular leader of the Eastern European Orthodox, particularly the Agudah-leaning.
