"For many Germans, self-determination was both persecution and promise. About ten million speakers of the German language, former subjects of the Habsburg monarchy, remained beyond Germany’s borders. Some three million such people inhabited the northwestern rim of Czechoslovakia, right at the border of Czechoslovakia and Germany. There were more Germans in Czechoslovakia than there were Slovaks. Almost the entire population of Austria, resting between Czechoslovakia and Germany, were German speakers. Austria was nevertheless required by the Treaty of St. Germain to exist as a separate state, although much of its population would have preferred accession to Germany. Adolf Hitler, the leader of the National Socialist German Workers Party established in 1920, was an Austrian and an advocate of an Anschluss: a unification of Austria and Germany. Such goals of national unity, dramatic as they were, actually concealed the full measure of Hitler’s ambitions."
