Odessa pogroms
A series of pogroms between Jews and other ethnicities in the city of Odessa, in the Russian Empire (now Ukraine), took place during the 19th and early 20th centuries. They occurred in 1821, 1859, 1871, 1881 and 1905.
According to Jarrod Tanny, most historians in the early 21st century agree that the earlier incidents were a result of "frictions unleashed by modernization," rather than by a resurgence of medieval antisemitism. The 1905 pogrom was markedly larger in scale, with economic and ethnic tensions playing a central role.
Odessa had a multi-ethnic population included Greek, Jewish, Russian, Ukrainian and other communities. Hundreds of people from all of these communities suffered from this mutual violence.
