time, St. Petersburg attempted to russify the former Congress Poland, joining Berlin in levying restrictions against use of the Polish language and cultural expression. Poles under Russian and German rule also endured official campaigns against the Roman Catholic Church: the Cultural Struggle (Kulturkampf) of Chancellor Otto von Bismarck to bring the Roman Catholic Church under state control and the Russian campaign to extend Orthodoxy throughout the empire. The Polish subjects under Austrian jurisdiction (after 1867 the Habsburg Empire was commonly known as Austria-Hungary) confronted a generally more lenient regime. Poles suffered no religious persecution in predominantly Catholic Austria, and Vienna counted on the Polish nobility as allies in the complex political calculus of its multinational realm. In return for loyalty, Austrian Poland, or Galicia, received considerable administrative and cultural autonomy. Galicia gained a reputation as an oasis of toleration amidst the oppression of German and Russian Poland. The Galician provincial Sejm acted as a semiautonomous parliamentary body, and Poles represented the region in the empire government in Vienna. In the late 19th century, the universities of Kraków and Lviv became the centers of Polish intellectual activity, and Kraków became the center of Polish art and thought. Even after the restoration of independence, many residents of southern Poland retained a touch of nostalgia for the days of the Habsburg Empire. Social and political transformation Profound social and economic forces operated on the Polish lands throughout the late 19th century, giving them a more modern aspect and altering traditional patterns of life. Especially in Russian Poland and the Silesian regions under German control, mining and manufacturing started on a large scale. This development sped the process of urbanization, and the emergence of capitalism began to reduce the relative importance of the landed aristocracy in Polish society. A considerable segment of the peasantry abandoned the overburdened land. Millions of Poles emigrated to North America and other destinations, and millions more migrated to cities to form the new industrial labour force. These shifts stimulated fresh social tensions. Urban workers bore the full range of hardships associated with early capitalism, and the intensely nationalistic atmosphere of the day bred frictions between Poles and the other peoples remaining from the old heterogeneous Commonwealth of Two Nations. The movement of the former noble class into cities created a new urban professional class. However, the peasants that tried to move to the cities, found all the better positions
