Ukrainization was thoroughly implemented through the government apparatus, Communist Party of Ukraine membership and, gradually, the party leadership as well, as the recruitment of indigenous cadre was implemented as part of the korenization policies. At the same time, the usage of Ukrainian was continuously encouraged in the workplace and in government affairs. While initially, the party and government apparatus was mostly Russian-speaking, by the end of the 1920s ethnic Ukrainians composed over one half of the membership in the Ukrainian communist party, the number strengthened by accession of Borotbists, a formerly indigenously Ukrainian "independentist" and non-Bolshevik communist party.
