The London Times reports.
The English word "pogrom" comes from the Yiddish (and Russian) word — "pogrom" — for destruction.
The OED definition: "In Russia, Poland, and some other East European countries in the late 19th and early 20th centuries: an organized massacre aimed at the destruction or annihilation of a body or class of people, esp. one conducted against Jewish people. "
The earliest English use was in 1889 ("This unprovoked attack of an armed force upon sleeping an defenseless prisoners is known..as ‘the pogróm of May 11’").
A second meaning, going back as far as 1906, is "An organized, officially tolerated, attack on any community or group." For example, in 1964, New Statesman wrote: "The charge that there had been a plot—a ‘pogrom’ in the contemporary phrase—to crush Ulster's resistance to Home Rule by force of arms."
