Input: Read this: Two rounds of Soviet purges directed by Moscow (19271934 and 19371938) resulted in the expulsion of nearly 10,000 people, from all levels of the Communist Party of Tajikistan. Ethnic Russians were sent in to replace those expelled and subsequently Russians dominated party positions at all levels, including the top position of first secretary. Between 1926 and 1959 the proportion of Russians among Tajikistan's population grew from less than 1% to 13%. Bobojon Ghafurov, Tajikistan's First Secretary of the Communist Party of Tajikistan from 19461956 was the only Tajikistani politician of significance outside of the country during the Soviet Era.
