A pogrom takes place in Lwów (now Lviv); over three days, at least 50 Jews and 270 Ukrainian Christians are killed by Poles.
The Lwów pogrom (Polish: pogrom lwowski, German: Lemberger Pogrom) was a pogrom perpetrated by Polish soldiers and civilians against the Jewish population of the city of Lwów (since 1945, Lviv, Ukraine). It happened on 21–23 November 1918, during the Polish–Ukrainian War that followed World War I.During three days of unrest in the city, an estimated 52–150 Jewish residents were killed, and hundreds were injured. Non-Jewish casualties were also reported. They were mainly Ukrainian, and they might have outnumbered the Jewish fatalities. The total number of victims was reported to be 340. It is estimated that over a thousand people, including some soldiers, were arrested by Polish authorities during and after the pogrom.The 1918 Lwów events were widely publicized in the international press. US President Woodrow Wilson appointed a commission, led by Henry Morgenthau, Sr., to investigate violence against the Jewish population in Poland. The Morgenthau Report was published in October 1919.
