The Pale of Settlement was a western region of the Russian Empire with varying borders that existed from 1791 to 1917 (de facto until 1915) in which permanent residency by Jews was allowed and beyond which Jewish residency, permanent or temporary, was mostly forbidden. Most Jews were still excluded from residency in a number of cities within the Pale as well. A few Jews were allowed to live outside the area, including those with university education, the ennobled, members of the most affluent of the merchant guilds and particular artisans, some military personnel and some services associated with them, including their families, and sometimes their servants. Pale is an archaic term meaning an enclosed area. Jews were also allowed to settle in colonies outside of the Pale, such as in Siberia.
The Pale of Settlement included all of modern-day Belarus and Moldova, much of Lithuania, Ukraine and east-central Poland, and relatively small parts of Latvia and what is now the western Russian Federation. It extended from the eastern pale, or demarcation line inside the country, westwards to the Imperial Russian border with the Kingdom of Prussia (later the German Empire) and Austria-Hungary. Furthermore, it comprised about 20% of the territory of European Russia and largely corresponded to historical lands of the former Polish–Lithuanian Commonwealth, Cossack Hetmanate, the Ottoman Empire (with Yedisan), Crimean Khanate, and eastern Principality of Moldavia (Bessarabia).
