when did prussia leave the holy roman empire
Holy Roman Empire During the Hohenstaufen period, German princes facilitated a successful, peaceful eastward settlement of lands that were uninhabited or inhabited sparsely by West Slavs. German speaking farmers, traders, and craftsmen from the western part of the Empire, both Christians and Jews, moved into these areas. The gradual Germanization of these lands was a complex phenomenon that should not be interpreted in the biased terms of 19th-century nationalism. The eastward settlement expanded the influence of the empire to include Pomerania and Silesia, as did the intermarriage of the local, still mostly Slavic, rulers with German spouses. The Teutonic Knights were invited to Prussia by Duke Konrad of Masovia to Christianize the Prussians in 1226. The monastic state of the Teutonic Order (German: Deutschordensstaat) and its later German successor state of Prussia were, however, never part of the Holy Roman Empire.
Austro-Prussian War The major result of the war was a shift in power among the German states away from Austrian and towards Prussian hegemony, and impetus towards the unification of all of the northern German states in a Kleindeutsches Reich that excluded the German Austria. It saw the abolition of the German Confederation and its partial replacement by a North German Confederation that excluded Austria and the other South German states. The war also resulted in the Italian annexation of the Austrian province of Venetia.
