Habsburg Realms

The "Habsburg Realms" (German: Die Habsburger Reiche) (Hungarian: A Habsburg Királyságok) was the collective name used for the Kingdom of Austria and the Kingdom of Hungary when they were separately ruled by the Habsburg crown between 1919 and 1934. The Habsburg crown stopped leading both countries when the "Fatherland Front" took over Austria and abolished the monarchy there.

While technically each kingdom was its sovereign state and had separate constitutions and parliaments, Hungary and Austria maintained allowed free movement of citizens and resources and shared a customs union. The monarch's role remained effective in multiple aspects of executive power, although the respective parliaments shared a considerable amount of power. The only instance in which the realms functioned as a single entity was in the League of Nations, this was to avoid the Habsburgs voting twice over the same topics.
