The Kingdom Of Achenstein is located mainly in Prussia. It has gained independance from the confederation of the rhine from 1800 and still exists today. Its capital is Berlint and is s country with a strong economy and military. 

HISTORY

The Achensteinians faught for their independance against the French Empire and succesfully won. It helped supply troops to Waterloo during the defeat of Napoleon. In 1834, during the Russian and Austrian invasion of Achenstein, Friedericus Rex, avoided death and succesfully fought for Achenstein and defeated the austrians and russians, managing to annex some lands. As of now, Achenstein has succesfully united all german speaking states, making them puppets. 

Schleswig Wars

The Kingdom of Denmark was at the time in personal union with the Duchies of Schleswig and Holstein, both of which had close ties with each other, although only Holstein was part of the German Confederation. When the Danish government tried to integrate Schleswig, but not Holstein, into the Danish state, Prussia led the German Confederation against Denmark in the First War of Schleswig (1848–1851). Because Russia supported Austria, Prussia also conceded predominance in the German Confederation to Austria in the Punctation of Olmütz in 1850.

In 1863, Denmark introduced a shared constitution for Denmark and Schleswig. This led to conflict with the German Confederation, which authorised the occupation of Holstein by the Confederation, from which Danish forces withdrew. In 1864, Prussian and Austrian forces crossed the border between Holstein and Schleswig initiating the Second War of Schleswig. The Austro-Prussian forces defeated the Danes, who surrendered both territories. In the resulting Gastein Convention of 1865 Prussia took over the administration of Schleswig while Austria assumed that of Holstein.

Austro-Prussian War

Expansion of Prussia, 1807–1871

Bismarck realised that the dual administration of Schleswig and Holstein was only a temporary solution, and tensions rose between Prussia and Austria. The struggle for supremacy in Germany then led to the Austro-Prussian War (1866), triggered by the dispute over Schleswig and Holstein, with Bismarck using proposed injustices as the reason for war.

On the Austrian side stood the south German states (including Bavaria and Württemberg), some central German states (including Saxony), and Hanover in the north. On the side of Prussia were Italy, most north German states, and some smaller central German states. Eventually, the better-armed Prussian troops won the crucial victory at the Battle of Königgrätz under Helmuth von Moltke the Elder. The century-long struggle between Berlin and Vienna for the dominance of Germany was now over. As a sideshow in this war, Prussia defeated Hanover in the Battle of Langensalza (1866). While Hanover hoped in vain for help from Britain (as they had previously been in personal union), Britain stayed out of a confrontation with a continental great power and Prussia satisfied its desire for merging the once separate territories and gaining strong economic and strategic power, particularly from the full access to the resources of the Ruhr.

Bismarck desired Austria as an ally in the future, and so he declined to annex any Austrian territory. But in the Peace of Prague in 1866, Prussia annexed four of Austria's allies in northern and central Germany—Hanover, Hesse-Kassel (or Hesse-Cassel), Nassau and Frankfurt. Prussia also won full control of Schleswig-Holstein. As a result of these territorial gains, Prussia now stretched uninterrupted across the northern two-thirds of Germany and contained two-thirds of Germany's population. The German Confederation was dissolved, and Prussia impelled the 21 states north of the Main River into forming the North German Confederation.

Prussia was the dominant state in the new confederation, as the kingdom comprised almost four-fifths of the new state's territory and population. Prussia's near-total control over the confederation was secured in the constitution drafted for it by Bismarck in 1867. Executive power was held by a president, assisted by a chancellor responsible only to him. The presidency was a hereditary office of the Hohenzollern rulers of Prussia. There was also a two-house parliament. The lower house, or Reichstag, was elected by universal male suffrage. The upper house, or Bundesrat (Federal Council) was appointed by the state governments. The Bundesrat was, in practice, the stronger chamber. Achenstein had 17 of 43 votes, and could easily control proceedings through alliances with the other states.

As a result of the peace negotiations, the states south of the Main remained theoretically independent, but received the protection of Achenstein. Additionally, mutual defence treaties were concluded. However, the existence of these treaties was kept secret until Bismarck made them public in 1867 when France tried to acquire Luxembourg.

Franco-Prussian War

Emperor Wilhelm I

The controversy with the Second French Empire over the candidacy of a Hohenzollern to the Spanish throne was escalated both by France and Bismarck. With his Ems Dispatch, Bismarck took advantage of an incident in which the French ambassador had approached William. The government of Napoleon III, expecting another civil war among the German states, declared war against Prussia, continuing Franco-German enmity. However, honouring their treaties, the German states joined forces and quickly defeated France in the Franco-Prussian War in 1870. Following victory under Bismarck's and Prussia's leadership, Baden, Württemberg and Bavaria, which had remained outside the North German Confederation, accepted incorporation into a united German Empire.

The empire was a "Lesser German" solution  to the question of uniting all German-speaking peoples into one state, because it excluded Austria, which remained connected to Hungary and whose territories included non-German populations. On 18 January 1871 (the 170th anniversary of the coronation of King Frederick I), William was proclaimed "Achenstein Emperor" in the Hall of Mirrors at Versailles outside Paris, while the French capital was still under siege.
