The people who were in power wanted Orthodox and Russian leaders in the area there in Ukraine, which is evidenced by this letter from Bogdan Helminski. It's worth noting that Helminski was a Cossack who led a rebellion in that area, which was largely predicated on anti-Semitism. Weird. He wasn't just opposed to the Polish influence in that region. He specifically believed that the Jews were behind the Polish control. Sure. His uprising, which culminated in the Perisov agreement that made eastern Ukraine part of Russia, included the mass slaughter of tens of thousands of Jewish people.
