Plundering the Judengasse (= Jewish Street) in Frankfurt am Main on 22 August 1614. Russian "pogroms" are quite a novel thing. It has started in earlier 19th century (coincidentally after incorporation of Poland into Russia) and most if not all the anti-Semitic violence in Russian Empire was contained to either Ukraine or Poland. An idea behind the alliance of the German Nazi and Ukrainian nationalists during WWII was mostly a shared belief that Bolshevism is a Jewish plot to ruin their civilizations.
