Russian was the most commonly studied foreign language at all levels of schooling during the Soviet era. Despite schooling available and administration conducted in local languages, Russian settlers were neither encouraged nor motivated to learn the official local languages, so knowledge of Russian became a practical necessity in daily life. Even to this day, the majority of the population of the Baltic states profess to be proficient in Russian, especially those who lived during Soviet rule. Meanwhile, the minority of Russian origin generally do not speak the national language. The question of their assimilation is a major factor in social and diplomatic affairs.
