In 1866 , the political map of Germany , which had largely remained unchanged since the Congress of Vienna, was rearranged. After Prussia's victory in the German War , some of its opponents are annexed , others are forced into alliances. The existing since 1815 German federal government is dissolved and instead of the North German Confederation under Prussian leadership established . Despite the victory in the naval battle of Lissa, the Austrian Empire, which was annihilated in the Battle of Königgrätz, had to cede territories to Italy , which was allied with Prussia .
In the Principality of Romania , the first Prince Alexandru Ioan Cuza is overthrown and replaced by the German Karl Eitel Friedrich, the son of Prince Karl Anton zu Hohenzollern-Sigmaringen , who ascends the Romanian throne as Carol I.

France and Austria are asked to withdraw the intervention troops from Mexico. With the exception of a few volunteer corps, the foreign units then leave the country, which makes the situation for Maximilian and his wife Charlotte of Belgium hopeless until the end of the year.
