Pogroms in the Russian Empire were large-scale, targeted, and repeated anti-Jewish rioting that began in the 19th century. Pogroms began to occur after Imperial Russia, which previously had very few Jews, acquired territories with large Jewish populations from the Polish–Lithuanian Commonwealth and the Ottoman Empire from 1772 to 1815. These territories were designated "the Pale of Settlement" by the Imperial Russian government, within which Jews were reluctantly permitted to live. The Pale of Settlement primarily included the territories of Poland, Ukraine, Belarus, Bessarabia, Lithuania and Crimea. Jews were forbidden from moving to other parts of European Russia, unless they converted from Judaism or obtained a university diploma or first guild merchant status. Migration to the Caucasus, Siberia, the Far East or Central Asia was not restricted.

A pogrom is a violent riot incited with the aim of massacring or expelling an ethnic or religious group, particularly Jews. The term entered the English language from Russian to describe 19th- and 20th-century attacks on Jews in the Russian Empire. Similar attacks against Jews which also occurred at other times and places became known retrospectively as pogroms. Sometimes the word is used to describe publicly sanctioned purgative attacks against non-Jewish groups. The characteristics of a pogrom vary widely, depending on the specific incident, at times leading to, or culminating in, massacres.
