Napoleon Bonaparte of the First French Empire enacted laws that first emancipated Jews in France, establishing them as equal citizens to other Frenchmen. In addition, in countries that he conquered during the Napoleonic Wars, he emancipated the Jews and introduced other ideas of freedom from the French Revolution. For instance, he overrode old laws restricting Jews to reside in ghettos, as well as lifting laws that limited Jews' rights to property, worship, and certain occupations.
Historians have disagreed about Napoleon's intentions in these actions, as well as his personal and political feelings about the Jewish community. Some have said he had political reasons but did not have sympathy for the Jews. His actions were generally opposed by the leaders of monarchies in other countries. After his defeat by Great Britain, a counter-revolution swept many of these countries and they restored discriminatory measures against the Jews.
The French Revolution abolished the different treatment of people according to religion or origin that had existed under the monarchy. Roman Catholicism had been the established state religion, closely tied historically to the monarchy, which represented both religious and political authority. The 1789 Declaration of the Rights of Man and of the Citizen guaranteed freedom of religion and free exercise of worship, provided that it did not contradict public order. At that time, most other European countries implemented measures that restricted the rights of people in their nations who practiced minority religions.
In the early 19th century, through his conquests in Europe, Napoleon Bonaparte spread the modernist ideas of revolutionary France: equality of citizens and the rule of law. Napoleon's personal attitude towards the Jews has been interpreted in various ways by different historians, as at various times he made statements both in support and opposition to the Jewish people. Historian Rabbi Berel Wein in Triumph of Survival: The Story of the Jews in the Modern Era 1650-1990 (1990) claims that Napoleon was interested primarily in seeing the Jews assimilate, rather than prosper as a distinct community: "Napoleon's outward tolerance and fairness toward Jews was actually based upon his grand plan to have them disappear entirely by means of total assimilation, intermarriage, and conversion."
