August 23, 1866, German region.
Prussia and Austria signed an armistice agreement in Prague, marking the end of the Austro-Prussian War.
The war lasted only seven weeks, hence it was also known as the Seven Weeks War, ending in a defeat for the Austrians.
This war laid the foundation for Prussia's unification of Germany, removing the major obstacle of Austria in the path to unifying the German states.
Meanwhile, Austria not only lost its leadership role in the German region due to the war but also triggered a domestic political crisis.
Faced with defeat and the rise of separatism, Austria had to compromise with the nobility in Hungary, paving the way for the Austrian Empire to become history, while the Austro-Hungarian Empire was about to take to the stage of history.
