Was Austria-Hungary a part of Germany?

Answer 1

Austria-Hungary was not a part of Germany; it was a monarchy ruled by Franz Josef the first, that split into pieces after the First World War. During the same period, Germany was run by Kaiser Wilhelm the first and the second.

___

Until 1866 Austria was part of the German Confederation and in fact officially the 'top dog' in Germany. In 1866 Prussia expelled Austria by force (in a war, that is) and dissolved the German Confederation. The following year Austria agreed to share power with Hungary, and Austria-Hungary was formed. So the answer above is technically correct but it is useful to have more background.

Answer 2

Austria is an independent country, and not part of modern Germany, although the Austrian people are Germans. Between 1938 and 1945, Austria was part of the "Greater German Reich", but regained independence after German defeat in WWII.
