Traditionally the imperial regime had been relatively tolerant of non-Russian cultures, languages, and religions. Much of the empire’s aristocracy was of non-Russian origin, spoke French by choice, and was not Orthodox in religion. In the second half of the 19th century, and in particular under Alexander III, the regime began emphasizing its Russianness. Increasing constraints were placed on non-Russian languages and cultures. Schools began teaching exclusively in Russian, administrative bodies could use only Russian, and publication in some languages was forbidden. To a degree these limitations followed trends evident elsewhere in Europe. The policy of Russification was also a response to fears that the multiethnic empire would disintegrate unless its population was drawn more closely together in culture and language. Whatever its motives, however, the policy of Russification caused great indignation among many non-Russians. The Jews were treated especially poorly: They were forced to live in certain areas, were not permitted to enter specific professions, and sometimes fell victim to murderous attacks by local Slavic mobs.
