The "Pale" included much of present-day Latvia, Lithuania, Belarus, Poland and Ukraine. It did not, however, encompass the key imperial cities of Moscow or Saint Petersburg, which were off-limits to Jews.
In history of Russia were several successful attempts, i.e. the Empress Elizabeth to remove Jews from Russia entirely unless they converted to Russian Orthodoxy.
The Pale was first created by Catherine the Great in 1791 for Crimea. The reasons for its creation were primarily economic and nationalist: while Russian society had traditionally been divided into nobles and serfs, Westernization led to the emergence of a middle class, which was rapidly being filled by Jews, who did not belong to either sector. By limiting their area of residence, the imperial powers were ensuring the growth of a native Russian middle class. Catherine can be said to have established the Pale as a compromise between those members of government who continued advocating the complete expulsion of the Jews, her own liberal tendencies, and the interests of the local population of the provinces, who suffered economically from the lack of a mercantile class of Jews.
The institution of the Pale became especially important to the Russian authorities following the Second Partition of Poland in 1793. While Russia's Jewish population had, until then, been rather limited, the annexation of Polish territory increased the Jewish population substantially, so that at its heyday, the Pale, which included the new Polish territories, had a Jewish population of over 4 million and constituted the largest concentration of Jews in the world.
Between 1791 and 1917, when the Pale officially ceased to exist, there were various reconfigurations of its boundaries, so that certain areas were open or shut to Jewish settlement, such as the Caucasus. Similarly, Jews were forbidden to live in agricultural communities, and forced to move to small provincial towns, fostering the rise of the shtetls (literally, "little cities," from the German stadt). Furthermore, in some periods, special dispensations were given for Jews to live in the major imperial cities, but these were tenuous, and several thousand Jews were expelled to the Pale from Saint Petersburg and Moscow as late as 1891.
The tribulations of Jewish life in the Pale of Settlement were immortalized in the writings of Yiddish authors such as the humorist Sholom Aleichem, whose stories of Tevye der milchiger (Tevye the Milkman) in the fictional shtetl of Anatevka form the basis of Fiddler on the Roof. Because of the harsh conditions of day-to-day life in the Pale, some 2 million Jews emigrated from there in the late-nineteenth-early twentieth century, mainly to the United States.
