Pogroms have been around for a long, long time. "Pogrom" is an English Loanword borrowed from Russian, which in turn borrowed it from Slavic Yiddish ("פאָגראָם"). Pogroms large and small were common in Russia and Europe. They mostly involved Jews as the targets; there is a saying in Russian "Know the Jew in Everything - Beware" ( "Во всем знай еврея и берегись!" )

Interesting that the Russian word for "Beware" (beregis in English spelling) has the root "Regis" or Emperor in Latin. So, inquiring minds will know that the Russians first confabulated "Emperor or Tsar of whom they should fear and be wary with the Jews also of whom they are historically fearful and wary.
