Anti-Jewish pogroms in the Russian Empire (Russian: Еврейские погромы в России; Hebrew: הסופות בנגב‎ ha-sufot ba-negev; lit. "the storms in the South") were large-scale, targeted, and repeated anti-Jewish rioting that first began in the 19th century. Pogroms began occurring after the Russian Empire, which previously had very few Jews, acquired territories with large Jewish populations from the Polish–Lithuanian Commonwealth during 1791–1835. These territories were designated "the Pale of Settlement" by the Imperial 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 the Russian Orthodox state religion.
