This chapter analyses how, in the context of the multinational Habsburg Empire, predominantly German-speaking members of the Christian Social movement considered the importance of this national side of their character. The Empire was buffeted by conflicts between bourgeois political representatives of different nationalities, but these became particularly acute for Christian Socials in Vienna when, as a cosmopolitan city, German speakers clashed with Czech speakers there. This chapter shows how, despite their claims to be universalist Christians, above such national disputes, Christian Socials were drawn into these Viennese clashes. It shows how this German dimension would be important for debates as to what should happen to German-speaking areas of Austria if the multinational Empire fell and collapsed, as many suspected it might under international stress.
