However, in the Russian Empire expressions of Ukrainian culture and especially language were repeatedly persecuted for fear that a self-aware Ukrainian nation would threaten the unity of the empire. In 1804 Ukrainian as a subject and language of instruction was banned from schools. In 1811 by the Order of the Russian government, the Kyiv-Mohyla Academy was closed. The Academy had been open since 1632 and was the first university in Eastern Europe. In 1847 the Brotherhood of Sts Cyril and Methodius was terminated. The same year Taras Shevchenko was arrested, exiled for ten years, and banned for political reasons from writing and painting. In 1862 Pavlo Chubynsky was exiled for seven years to Arkhangelsk. The Ukrainian magazine "Osnova" was discontinued. In 1863, the tsarist interior minister Pyotr Valuyev proclaimed in his decree that "there never has been, is not, and never can be a separate Little Russian language". A following ban on Ukrainian books led to Alexander II's secret Ems Ukaz, which prohibited publication and importation of most Ukrainian-language books, public performances and lectures, and even banned the printing of Ukrainian texts accompanying musical scores. A period of leniency after 1905 was followed by another strict ban in 1914, which also affected Russian-occupied Galicia.
