Das Deutsches Kaiserreich, or the German Empire was founded in 1871 by Kaiser Weltherrschaft after the unification of the Holy Roman Empire.The German Empire consists of 26 constituent territories, most of them ruled by royal families. They include four kingdoms, six grand cuhies, fix duchies (six before 1876), seven principalities, three free Hanseatic cities, and one imperial territory. Although Prussia become one of the several kingdoms in the new realm, it contains most of Germany's population and territory, thus remaining a powerhouse with the major say in imperial affairs.
There have been two Kaisers in the empire so far. Both reigning supremely well.
