The Confederation thus formed lasted, with hardly any change that concerns geography, till the war of 1866. ♦Division of Luxemburg, 1831.♦ The Grand Duchy of _Luxemburg_, which had, by the arrangements of 1815, been held by the King of the Netherlands as a member of the German Confederation, was, on the separation of Belgium and the Netherlands, cut into two parts. Part was added to Belgium; another part, though quite detached from the kingdom of the Netherlands, was held by its king as a member of the Confederation. In 1839 he also entered it for the Duchy of Limburg. ♦War in Sleswick and Holstein, 1848-1851.♦ The internal movements which began in 1848, and the war in _Sleswick_ and _Holstein_ which began in the same time, led to no lasting geographical changes. In 1849 the Swabian principalities of Hohenzollern were joined to the Prussian crown. ♦Cession of the Duchies to Austria and Prussia, 1864.♦ The last Danish war ended by the cession of Sleswick and Holstein, together with Lauenburg, to Prussia and Austria jointly, an arrangement in its own nature provisional. Austria ceded her right in Lauenburg to Prussia in the next year, and in the next year again came the Seven Weeks’ War, and the great geographical changes which followed it. ♦Abolition of the Confederation. | Exclusion of Austria. | North-German Confederation. | Cession of Sleswick and Holstein to Prussia, 1866.♦ The German Confederation was abolished; Austria was shut out from all share in German affairs, and she ceded her joint right in Sleswick and Holstein to Prussia. ♦Prussian annexations.♦ The Northern states of Germany became a distinct Confederation under the presidency of Prussia, whose immediate dominion was increased by the annexation of the kingdom of _Hannover_, the duchy of _Nassau_, the electorate of _Hessen_, and the city of _Frankfurt_. The States south of the Main, Bavaria, Württemberg, Baden, and the southern part of Hessen-Darmstadt, remained for a while outside of the new League. ♦All the Prussian lands admitted to the Confederation.♦ The non-German dominions of Prussia, Prussia strictly so called with the Polish duchy of Posen and the newly acquired land of Sleswick, were now incorporated with the Confederation; on the other hand, all that Austria had held within the Confederation was now shut out of it. ♦Settlement of Luxemburg, 1867.♦ _Luxemburg_ also was not included in the new League, and, after some disputes, it was in the next year recognized as a neutral territory under its own duke the King of the Netherlands. ♦Liechtenstein.♦ The little principality of _Liechtenstein_ was perhaps forgotten altogether; but, as not being included in the Confederation, nor yet incorporated with anything else, it must be looked on as becoming an absolutely independent state. ♦Great geographical changes, 1866.♦ Thus the geographical frontiers of Germany underwent, at a single blow, changes as great as they had undergone in the wars of the French Revolution.
