Azerbaijan Soviet Socialist Republic, the women's literacy campaign was largely carried out by members of the Ali Bayramov Club, a women's organization founded by Azeri Bolshevik women in Baku in 1920. The most active phase of likbez lasted until 1939. In 1926, the literacy rate was 56.6 percent of the population. By 1937, according to census data, the literacy rate was 86% for men and 65% for women, making a total literacy rate of 75%. An important aspect of the early campaign for literacy and education was the policy of "indigenisation" (korenizatsiya). This policy, which lasted essentially from the mid-1920s to the late 1930s, promoted the development and use of non-Russian languages in the government, the media, and education. Intended to counter the historical practices of Russification, it had as another practical goal assuring native-language education as the quickest way to increase educational levels of future generations. A huge network of so-called "national schools" was established by the 1930s, and this network continued to grow in enrollments throughout the Soviet era. Language policy changed over time, perhaps marked first of all in the government's mandating in 1938 the teaching of Russian as a required subject of study in every non-Russian school, and then especially beginning in the latter 1950s a growing conversion of non-Russian schools to Russian as the main medium of instruction. However, an important legacy of the native-language and bilingual education policies over the years was the nurturing of widespread literacy in dozens of languages of indigenous nationalities of the USSR, accompanied by widespread and growing bilingualism in which Russian was said to be the "language of internationality communication." In 1923 a new school statute and curricula were adopted. Schools were divided into three separate types, designated by the number of years of instruction: "four year", "seven year" and "nine year" schools. Seven and nine-year (secondary) schools were scarce, compared to the "four-year" (primary) schools, making it difficult for the pupils to complete their secondary education. Those who finished seven-year schools had the right to enter Technicums. Only nine-year school led directly to university-level education. The curriculum was changed radically. Independent subjects, such as reading, writing, arithmetic, the mother tongue, foreign languages, history, geography, literature or science were abolished. Instead school programmes were subdivided into "complex themes", such as "the life and labour of the family in village and town" for the first year or "scientific organisation of
