The term "pogrom" in the meaning of large-scale, targeted, and repeated anti-Jewish rioting, saw its first use in the 19th century, in reference to the anti-Jewish pogroms in the Russian Empire. Pogroms began occurring after the Russian Empire, which previously had very few Jews, acquired territories with large Jewish populations during 1791-1835. These territories were designated "the Pale of Settlement" by the Russian government, within which Jews were reluctantly permitted to live, and it was within them that the pogroms largely took place. Most Jews were forbidden from moving to other parts of the Empire, unless they converted to Orthodox Christianity.
