After the sovietization of Georgia in 1921, followed by suppression of an armed rebellion against the new regime in 1924, many leading nationalist intellectuals went in exile in Europe. In the Soviet Union, Georgian nationalism went underground or was rechanneled into cultural pursuits, becoming focused on the issues of language, promotion of education, protection of old monuments, literature, film, and sports. Any open manifestation of local nationalism was repressed by the Soviet state, but it did provide cultural frameworks and, as part of its policy of korenizatsiya, helped institutionalize the Georgians as a "titular nationality" in the Georgian Soviet Socialist Republic. Thus, by maintaining the focus of Georgian nationalism on cultural issues, the Soviet regime was able to prevent it from becoming a political movement until the 1980s "perestroika" period.
