 Lviv was home to the Polish Ossolineum, with the second largest collection of Polish books in the world, the Polish Academy of Arts, the Polish Historical Society, the Polish Theater and Polish Archdiocese.Similarly, the city also served as an important centre of the Ukrainian patriotic movement and culture, unlike other parts of Ukraine under Russian rule, where, prior to 1905, all publications in Ukrainian were prohibited as part of an intense Russification campaign.The city housed the largest and most influential Ukrainian institutions in the world, including the Prosvita society dedicated to spreading literacy in the Ukrainian language, the Shevchenko Scientific Society, the Dniester Insurance Company and base of the Ukrainian cooperative movement, and it served as the seat of the Ukrainian Catholic Church.
