I would think that, if you wanted to pick a language that no ethnic group actually speaks, you could choose a language with more favorable outcomes for international trade, like English or French, or a language like Latin that already tangentially connects the population through the Church.I credit part of this to their mandatory education of Esperanto in *every* school of their nation – no one ethnicity dominates, everyone has to learn a language that is not their own, and that becomes the means of communication.
If the German Empire is still around as well, then German is probably the most common business language for Central and Eastern Europe. This TL will probably be much better for Europe's Jews and the Yiddish language as well. Yiddish has a chance to flourish in a consociational state like Greater Austria.I would think that, if you wanted to pick a language that no ethnic group actually speaks, you could choose a language with more favorable outcomes for international trade, like English or French, or a language like Latin that already tangentially connects the population through the Church.
