As a result, the Republic of Austria lost roughly 60% of the old Austrian Empire's territory. It also had to drop its plans for union with Germany, as it was not allowed to unite with Germany without League approval.
The new Austrian state was, at least on paper, on shakier ground than Hungary. Unlike its former Hungarian partner, Austria had never been a nation in any real sense. While the Austrian state had existed in one form or another for 700 years, it was united only by loyalty to the Habsburgs. With the loss of 60% of the Austrian Empire's prewar territory, Vienna was now a lavish and oversized imperial capital lacking an empire to support it, thus being sarcastically referred to as the “national hydrocephalus”.
However, after a brief period of upheaval and the Allies' foreclosure of union with Germany, Austria established itself as a federal republic. Despite the temporary Anschluss with Nazi Germany, it still survives today. Adolf Hitler cited that all "Germans" – such as him and the others from Austria, etc. – should be united with Germany.
