The changed situation of Western Jewry in the 19th-20th centuries caused Jews to revise their conceptions of Jewry as a community and of its place in the world. Six Judaic systems emerged. Discusses each one in detail. While the 19th-century trends (Orthodox, Reform, and Conservative) developed in response to the needs of integration with the non-Jewish world, the 20th-century Judaisms (Zionism, Jewish Socialism and Yiddishism, and the American Judaism of Holocaust and Redemption) were a response to aggressive antisemitism and to the crisis caused by the rapid social and economic restructuring of Central and Eastern Europe. The events of May-June 1967 in the Middle East brought about a new trend - Holocaust and Redemption Judaism, in the center of which are the Holocaust (mythicized and perceived as a metaphor for absolute evil) and the State of Israel (perceived as the redemption for the Holocaust). This Judaism contains a salvific myth and possesses all the traits of a religious system. The exposition is accompanied by excerpts from books and articles.
