Between 1918 and 1921 more than a thousand pogroms were recorded across Ukraine and Belarus as authority collapsed and armies moved back and forth. Nicolas Werth, in the Sciences Po Mass Violence encyclopedia, records approximately 150,000 Jewish victims, 125,000 in Ukraine and 25,000 in Belarus, with 1919 the deadliest year; other counts of those killed outright are lower, in the range of 50,000-100,000, with the remainder dying of wounds, hunger and epidemic. The perpetrators included the White Volunteer Army, whose Ukrainian campaign of 1919 was accompanied by systematic pogroms, detachments nominally under the Ukrainian People's Republic, independent bands under warlords such as Hryhoriv, and, less often, Red Army units, some of whose members were shot for it. Communities were robbed, houses burned, women raped and entire shtetl populations killed. The violence was documented at the time by Jewish investigating commissions whose archives were later published, and it is widely regarded as the largest killing of Jews in Europe between the Chmielnicki massacres and the Holocaust.

The 1897 census counted about 1.9 million Jews in the nine Ukrainian provinces and the 1926 Soviet census 1.57 million in the Ukrainian SSR, bracketing a wartime population of roughly 1.6 million. Estimates of those killed in the pogroms range from about 50,000 to 200,000, with several hundred thousand more left homeless, orphaned or destitute across more than a thousand recorded pogroms.
Werth gives approximately 150,000 Jewish victims for 1918-22. Counts restricted to those killed outright in identified pogroms are lower, commonly 50,000-60,000; totals that include deaths from wounds, exposure, hunger and the typhus that followed the destruction of communities reach 150,000-200,000. The disagreement is between narrow and broad definitions of victim and between the different investigating commissions' records.
Killings, mass rape and the burning and looting of Jewish quarters were documented contemporaneously by Jewish investigating commissions in Kyiv whose archives underlie Shtif's account and Werth's summary.
