Https://en.wikipedia.org/wiki/zydokomuna the entire article the whole way through just constantly disproves itself as it tries to frame the narrative that it's all a false canard another important factor was the dominance of jews in the leadership of the communist party of poland (kpp). according to multiple sources, jews were well represented in the kpp.3744 notably, the party had strong jewish representation at higher levels. in january 1936 the national composition of the central party authorities were as follows: out of the 19 kc (central committee) kpp members 11 were polish, 6 were jewish (31,6%), 1 was belarusian and 1 ukrainian.45 jews made up 28 out of the 52 individuals of the "district activists" of the kpp (53.8%), 75% of its "publication apparatus", 90% of the "international department for help to revolutionaries", and 100% of the "technical apparatus" of the home secretariat. in polish court proceedings against communists between 1927 and 1936, 90% of the accused were jews. following the 1939 soviet invasion of poland, resulting in the partition of polish territory between nazi germany and the soviet union (ussr), jewish communities in eastern poland welcomed with some relief the soviet occupation, which they saw as a "lesser of two evils" than openly antisemitic nazi germany.535455 the image of jews among the belorussian and ukrainian minorities waving red flags to welcome soviet troops had great symbolic meaning in polish memory of the period.56 jan t. gross noted that "there were proportionately more communist sympathizers among jews than among any other nationality in the local population".55 in the days and weeks following the events of september 1939, the soviets engaged in a harsh policy of sovietization. polish schools and other institutions were closed, poles were dismissed from jobs of authority, often arrested and deported, and replaced with non-polish personnel many poles resented their change of fortunes because, before the war, poles had a privileged position compared to other ethnic groups of the second republic. then, in the space of a few days, jews and other minorities from within poland (mainly ukrainians and belorussians) occupied newly vacant positions in the soviet occupation government and administration—such as teachers, civil servants and engineers—positions that some claimed they had trouble achieving under the polish government.6263 what to the majority of poles was occupation and betrayal was, to some jews—especially polish communists of jewish descent who emerged from the underground—an opportunity for revolution and retribution.6364
