Prussia went to war with Austria and beat Denmark
Austria and Prussia declared war on Denmark to regain the provinces of Schleswig and Holstein, which were ruled by the Danish crown but were predominantly German-speaking.
The Second Schleswig War began on February 1, 1864 when Prussia crossed into Schleswig. It was fought between Denmark, Prussia and Austria.
Denmark lost Schleswig-Holstein (Slesvig-Holsten) in 1864 when they lost a war against Prussia and Austria
Yes, they lost a part of France, a bit to Denmark, and Austria.
The Austro-Prussian War (against Austria)and The two Schleswig Wars (against Denmark)
Primarily in Denmark, but there is also approx. 50.000 living south of the Danish-German border. They became Prussian, and later German, citizens as a consequence of the 1864 war with Prussia and Austria (and subsequent war between Prussia and Austria), but remain culturally Danish. Aprox. 10% of the Greenland population are ethnic Danes.
Effect : Austria-Hungary mobilized for war
1. The Danish War- Against Denmark 2. The Seven Weeks' War- Against Austria 3. The Franco-Prussian War- Against France AAL
The German Empire, established in 1871, expanded its territory at the expense of neighboring states, notably France, Austria, and Denmark. France lost the provinces of Alsace and Lorraine following the Franco-Prussian War in 1871. Denmark ceded Schleswig and Holstein to Germany after the Second Schleswig War in 1864, while Austria lost its influence and territory in the region following the Austro-Prussian War in 1866, leading to the exclusion of Austria from German affairs.
Although Hitler was of Austrian decent, Austria like Switzerland was neutral in the second world war, so therefore it was not involved and the effect was minimal.
The domino effect was when one country declared war on another, allied countries would get involved also eg. Austria-Hungary declared war on Serbia, Russia stepped in to help Serbia and then Germany stepped in to help Austria-Hungary and so on.. hope that helps :D
