Babi Yar was mentioned in the orginal post. Additional facts were helpful, hopefully, to all readers of the thread.
Not mentioned was the Lviv Pogram in 1941 which was initiated by the Organization of Ukrainian Nationalists.
“The surprise German invasion of the U.S.S.R. began on June 22, 1941. The Soviets, during their hasty retreat, shot their political prisoners and, whenever possible, evacuated personnel, dismantled and removed industrial plants, and conducted a scorched-earth policy—blowing up buildings and installations, destroying crops and food reserves, and flooding mines. Almost four million people were evacuated east of the Urals for the duration of the war. The Germans moved swiftly, however, and by the end of November VIRTUALLY ALL OF UKRAINE WAS UNDER NAZI CONTROL.

Initially, the Germans were greeted as liberators by SOME of the Ukrainian populace. In Galicia especially, there had long been a widespread belief that Germany, as the avowed enemy of Poland and the U.S.S.R., was the Ukrainians’ natural ally for the attainment of their independence.
The illusion was quickly shattered.
In the occupied territories, the Nazis sought to implement their “racial” policies. In the fall of 1941 began the mass killings of Jews that continued through 1944. An estimated 1.5 million Ukrainian Jews perished, and over 800,000 were displaced to the east; at Baby Yar (Ukrainian: Babyn Yar) in Kyiv, nearly 34,000 were killed in just the first two days of massacre in the city. [See also Holocaust: The Einsatzgruppen.]
In the Reichskommissariat, ruthlessly administered by Erich Koch, Ukrainians were slated for servitude. The collective farms, whose dissolution was the fervent hope of the peasantry, were left intact, industry was allowed to deteriorate, and the cities were deprived of foodstuffs as all available resources were directed to support the German war effort. Some 2.2 million people were taken from Ukraine to Germany as slave labourers (Ostarbeiter, or “eastern workers”). Cultural activities were repressed, and education was limited to the elementary level.
Under such conditions of brutality, Ukrainian political activity, predicated originally on cooperation with the Germans, increasingly turned to underground organizational work and resistance. The OUN groups that streamed eastward in 1941 were soon subjected by the German authorities to repressive measures, including execution, so they propagated their nationalist views clandestinely and, through their contact with the local population, began to revise their ideology in a more democratic, pluralist direction.”
Yup. Bad shit all around.
The first Russian pogroms took place in the early 1820s, in Ukraine (Odessa, I think). And they pretty much became regular events in the 1880s, continuing until the 1940s.
Ukraine and Bessarabia (Moldova) were the primary sites of the pogroms.
