Haskalah the Jewish Enlightenment
During the period of the European Renaissance and Enlightenment, significant changes were happening within the Jewish community. The Haskalah movement paralelled the wider Enlightenment, as Jews began in the 1700s to campaign for emancipation from restrictive laws and integration into the wider European society. Secular and scientific education was added to the traditional religious instruction received by students, and interest in a national Jewish identity, including a revival in the study of Jewish history and Hebrew, started to grow.
Haskalah gave birth to the Reform and Conservative movements and planted the seeds of Zionism while at the same time encouraging cultural assimilation into the countries in which Jews resided. At around the same time another movement was born, one preaching almost the opposite of Haskalah, Hasidic Judaism. Hasidic Judiasm began in the 1700s by Rabbi Israel Baal Shem Tov, and quickly gained a following with its more exubarent, mystical approach to religion. These two movements, and the traditional orthodox approach to Judiasm from which they spring, formed the basis for the modern divisions within Jewish observance.
At the same time, the outside world was changing. Though persecution still existed in some European countries (hundreds of thousands of Jews were killed in pogroms in the 18th and 19th centuries), Napoleon invited Jews to leave the Jewish ghettos in Europe and seek refuge in the newly created tolerant political regimes that offered equality under Napoleonic Law (see Napoleon and the Jews). At the same time, Jewish migration to the United States (see Jews in the United States) created a new community in large part freed of the restrictions of Europe.
