Here is Austro-Japanese aristocrat Richard von Coudenhove-Kalergi's 1920s proposal for five global super-states:
The global super-states on the legend of this map are, translated to English and in their proper order:
-The British Empire (or, alternatively, the British Realm)

Coudenhove-Kalergi was, of course, also a huge fan of the idea of a United States of Europe, an idea that Adolf Hitler criticized at the time but which later to a large extent became a reality in the post-World War II years and decades.
