On the morning of October 25, 1864, Franz, who had just awakened from his sleep, was stunned by the news that the Prussian Government had declared war on the Kingdom of Denmark.
To be precise, the two countries had already declared war yesterday afternoon. The news reached Vienna late at night, and the astute staff waited to report it until Franz was up.
There had been no recruitment efforts whatsoever in advance, and the two nations suddenly went to war. As for the Prussian pretext for "liberating German brethren," Franz outright ignored it.
An excuse for war is good enough. In history, the Prussians have carried the banner of defending the sovereignty of the Germany Region, but under the butterfly effect of Franz, the Berlin Government no longer dared to flaunt this banner.
With the revival of Austria, slogans and mottos related to "German unification" gradually disappeared from the official documents of the Prussian Government.
