Bohemia, Moravia and Silesia, the former Crownlands of Austria-Hungary which now make up the western half of Czechoslovakia, had for centuries a population mixture of 40% German, 60% Czech. The national reawakening of the eighteenth and nineteenth centuries pitted the majority Czechs against their German minority master. This, coupled with the social upheavals caused by the industrial revolution, brought Czechs and Germans in Bohemia to center stage in the nationality conflict in the multinational Empire.
