cover for organizing their anti-Soviet resistance. In order to stop this, the decree ordered in these areas, among other things, to switch to Russian all newspapers and magazines, and all Soviet and cooperative paperwork. By the autumn of 1932 (beginning of a school year), all schools were ordered to switch to Russian. In addition the decree ordered a massive population swap: all "disloyal" population from a major Cossack settlement, stanitsa Poltavskaya was banished to Northern Russia, with their property given to loyal kolkhozniks moved from poorer areas of Russia. This forced end to Ukrainization in southern RSFSR had led to a massive decline of reported Ukrainians in these regions in the 1937 Soviet Census compared to the 1926 First All-Union Census of the Soviet Union. 1930s to mid-1980 The Communist Party of Ukraine, under the guidance of state officials like Lazar Kaganovich, Stanislav Kosior, and Pavel Postyshev, boasted in early 1934 of the elimination of "counter-revolutionaries, nationalists, spies and class enemies". Whole academic organizations, such as the Bahaliy Institute of History and Culture, were shut down following the arrests. In 1935–36, 83% of all school children in the Ukrainian SSR were taught in Ukrainian even though Ukrainians made up about 80% of the population. In 1936 from 1830 newspapers 1402 were in Ukrainian, as were 177 magazines, in 1936 69,104 thousand Ukrainian books were printed. In the following fifty years the Soviet policies towards the Ukrainian language mostly varied between quiet discouragement and suppression to persecution and cultural purges, with the notable exception for the decade of Petro Shelest's Communist Party leadership in the Soviet Ukraine (1963–1972). The mid-1960s were characterized by moderate Ukrainization efforts in governmental affairs as well as the resurgence of the usage of Ukrainian in education, publishing and culture. Eventually, all effects of Ukrainization were undone yet again and Ukraine gradually became russified to a significant degree. These policies softened somewhat only in the mid-to-late 1980s and were completely reversed again in newly independent Ukraine in the 1990s. Post-1991: Independent Ukraine On 28 October 1989, the Supreme Soviet of Ukraine changed the Constitution and adopted the "Law of Languages". The Ukrainian language was declared the only official language, while the other languages spoken in Ukraine were guaranteed constitutional protection. The government was obliged to create the conditions required for the development and use of Ukrainian language as well as languages of other ethnic groups, including Russian.
