 Other Ukrainians came under the policy of Romanianization following the collapse of Austria-Hungary over the whole of Bukovina and relinquishment of Russian Empire over Bessarabia in 1918; the Romanianization policies brought the closure of the Ukrainian public schools (all such schools were closed until 1928) and the suppression of most of the Ukrainian (Ruthenian) cultural institutions.The very term "Ukrainians" was prohibited from the official usage and some Romanians of disputable Ukrainian ethnicity were rather called the "citizens of Romania who forgot their native language" and were forced to change their last names to Romanian-sounding ones.Among those who were Romanianized were descendants of Romanians who were assimilated to Ukrainian society in the past.
