In 1990, Russian became legally the official all-Union language of the Soviet Union, with constituent republics having rights to declare their own official languages. In 1989, the Ukrainian SSR government adopted Ukrainian as its official language, which was affirmed after the fall of the Soviet Union as the only official state language of the newly-independent Ukraine. The educational system was transformed over the first decade of independence from a system that was overwhelmingly Russian to one in which over 75% of tuition was in Ukrainian. The government has also mandated a progressively increased role for Ukrainian in the media and commerce.
