The All-Ukrainian Sovnarkom's decree "On implementation of the Ukrainization of the educational and cultural institutions" (July 27, 1923) is considered to be the onset of the Ukrainization program. The (August 1) decree that followed shortly "On implementation of the equal rights of the languages and facilitation of the Ukrainian language" mandated the implementation of Ukrainian language to all levels of state institutions. Initially, the program was met with resistance by some Ukrainian Communists, largely because non-Ukrainians prevailed numerically in the party at the time. The resistance was finally overcome in 1925 through changes in the party leadership under the pressure of Ukrainian representatives in the party. In April 1925 the party Central Committee adopted the resolution on Ukrainization proclaiming its aim as "solidifying the union of the peasantry with the working class" and boosting the overall support of the Soviet system among Ukrainians. A joint resolution aimed at "complete Ukrainization of the Soviet apparatus" as well as the party and trade unions was adopted on April 30, 1925. The Ukrainian Commissariat of Education (Narkomos) was charged with overseeing the implementation of the Ukrainization policies. The two figures, therefore, most identified with the policy are Oleksander Shumskyi, the Commissar for Education between 1923 and 1927, and Mykola Skrypnyk, who replaced Shumskyi in 1927.
