In 2001, the city centre was designated a UNESCO World Heritage Site.  - The Kingdom of Prussia was a German kingdom that constituted the state of Prussia between 1701 and 1918 and included parts of present-day Germany, Poland, Russia, Lithuania, Denmark, Belgium and the Czech Republic. It was the driving force behind the unification of Germany in 1871 and was the leading state of the German Empire until its dissolution in 1918. Although it took its name from the region called Prussia, it was based in the Margraviate of Brandenburg, where its capital was Berlin.  - The Austrian Empire (modern spelling "") was an empire in Central Europe created out of the realms of the Habsburgs by proclamation in 1804. It was a multinational empire and one of Europe's great powers. Geographically it was the second largest country in Europe after the Russian Empire (621,538 square kilometres [239,977 sq mi]). It was also the third most populous after Russia and France, as well as the largest and strongest country in the German Confederation. Proclaimed in response to the First French Empire, it overlapped with the Holy Roman Empire until the latter's dissolution in 1806. The "Ausgleich" of 1867 elevated Hungary's status. It became a separate entity from the Empire entirely, joining with it in the dual monarchy of Austria-Hungary.  - Austria-Hungary, often referred to as the Austro-Hungarian Empire in English-language sources, was a constitutional union of the Austrian Empire (the Kingdoms and lands represented in the Imperial Council, or "Cisleithania") and the Kingdom of Hungary (Lands of the Crown of Saint Stephen or "Transleithania") that existed from 1867 to 1918, when it collapsed as a result of defeat in World War I. The union was a result of the Austro-Hungarian Compromise of 1867 and came into existence on 30 March 1867. Austria-Hungary consisted of two monarchies (Austria and Hungary), and one autonomous region: the Kingdom of Croatia-Slavonia under the Hungarian crown, which negotiated the CroatianHungarian Settlement ("Nagodba") in 1868. It was ruled by the House of Habsburg, and constituted the last phase in the constitutional evolution of the Habsburg Monarchy. Following the 1867 reforms, the Austrian and the Hungarian states were co-equal. Foreign affairs and the military came under joint oversight, but all other governmental faculties were divided between respective states.  - The German Revolution or November Revolution was a civil conflict in the German Empire at the end of the First World War that resulted in the replacement of Germany's Imperial government with a republic. The revolutionary period lasted from November 1918 until the establishment in August 1919 of a republic that later became known as the Weimar Republic.  - The Electorate of Bavaria was an independent hereditary electorate of the Holy Roman Empire from 1623 to 1806, when it was succeeded by the Kingdom of Bavaria.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017.

The town of Aschaffenburg is not considered part of the district of Aschaffenburg, but is the administrative seat.  - The Napoleonic Wars (1803-1815) were a series of major conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European powers formed into various coalitions, primarily led and financed by the United Kingdom. The wars resulted from the unresolved disputes associated with the French Revolution and the Revolutionary Wars, which had raged on for years before concluding with the Treaty of Amiens in 1802. The resumption of hostilities the following year paved the way for more than a decade of constant warfare often categorized into five conflicts: the War of the Third Coalition (1805), the War of the Fourth Coalition (1806-7), the War of the Fifth Coalition (1809), the War of the Sixth Coalition (1813), and the War of the Seventh Coalition (1815). The Napoleonic Wars had profound consequences for global and European history, leading to the spread of nationalism and liberalism, the rise of the British Empire as the world's premier power, the independence movements in Latin America and the collapse of the Spanish Empire, the fundamental reorganization of German and Italian territories into larger states, and the establishment of radically new methods in warfare.   - Weimar Republic is an unofficial, historical designation for the German state between 1919 and 1933. The name derives from the city of Weimar, where its constitutional assembly first took place. The official name of the state was still "Deutsches Reich"; it had remained unchanged since 1871. In English the country was usually known simply as Germany. A national assembly was convened in Weimar, where a new constitution for the "Deutsches Reich" was written, and adopted on 11 August 1919. In its fourteen years, the Weimar Republic faced numerous problems, including hyperinflation, political extremism (with paramilitaries  both left- and right-wing); and contentious relationships with the victors of the First World War. The people of Germany blamed the Weimar Republic rather than their wartime leaders for the country's defeat and for the humiliating terms of the Treaty of Versailles. However, the Weimar Republic government successfully reformed the currency, unified tax policies, and organized the railway system. Weimar Germany eliminated most of the requirements of the Treaty of Versailles; it never completely met its disarmament requirements, and eventually paid only a small portion of the war reparations (by twice restructuring its debt through the Dawes Plan and the Young Plan). Under the Locarno Treaties, Germany accepted the western borders of the republic, but continued to dispute the Eastern border.  - Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia.

It was the first Lutheran duchy with a dominant German-speaking population, as well as Polish and Lithuanian minorities. In old texts and in Latin, the term "Prut(h)enia" refers alike to "Ducal Prussia", its western neighbor Royal Prussia, and their common predecessor, Teutonic Prussia. The adjectival form of the name was "Prut(h)enic".  - Count (male) or countess (female) is a title in European countries for a noble of varying status, but historically deemed to convey an approximate rank intermediate between the highest and lowest titles of nobility. The word "count" came into English from the French "comte", itself from Latin "comes"in its accusative "comitem"meaning companion, and later companion of the emperor, delegate of the emperor. The adjective form of the word is "". The British and Irish equivalent is an earl (whose wife is a "countess", for lack of an English term). Alternative names for the "count" rank in the nobility structure are used in other countries, such as "Graf" in Germany and "Hakushaku" during the Japanese Imperial era.  - The concept of Germany as a distinct region in central Europe can be traced to Roman commander Julius Caesar, who referred to the unconquered area east of the Rhine as "Germania", thus distinguishing it from Gaul (France), which he had conquered. The victory of the Germanic tribes in the Battle of the Teutoburg Forest (AD 9) prevented annexation by the Roman Empire, although the Roman provinces of Germania Superior and Germania Inferior were established along the Rhine. Following the Fall of the Western Roman Empire, the Franks conquered the other West Germanic tribes. When the Frankish Empire was divided among Charlemagne's heirs in 843, the eastern part became East Francia. In 962, Otto I became the first emperor of the Holy Roman Empire, the medieval German state.  - The Holy Roman Empire was a multi-ethnic complex of territories in central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806.

Although it has the second-smallest area (Vienna is the smallest) and population (Burgenland is less populated), it has the second-highest population density (after Vienna). It borders three countries: Germany (Bavaria and Baden-Württemberg via Lake Constance), Switzerland (Graubünden and St. Gallen) and Liechtenstein. The only Austrian state that shares a border with Vorarlberg is Tyrol to the east.  - The German Confederation was an association of 39 German states in Central Europe, created by the Congress of Vienna in 1815 to coordinate the economies of separate German-speaking countries and to replace the former Holy Roman Empire. Most historians have judged the Confederation to have been weak and ineffective, as well as an obstacle to the creation of a German nation-state. It collapsed due to the rivalry between Prussia and Austria, warfare, the 1848 revolution, and the inability of the multiple members to compromise.  - An empire is defined as "an aggregate of nations or people ruled over by an emperor or other powerful sovereign or government, usually a territory of greater extent than a kingdom, as the former British Empire, French Empire, Brazilian Empire, Russian Empire, Ottoman Empire, Byzantine Empire or Roman Empire."

While the Alps occupy the greater part of the territory, the Swiss population of approximately eight million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva.  - The Kingdom of Bavaria ( German : Königreich Bayern ) was a German state that succeeded the former Electorate of Bavaria in 1805 and continued to exist until 1918 . The Bavarian Elector Maximilian IV Joseph of the House of Wittelsbach became the first King of Bavaria in 1805 as Maximilian I Joseph . The crown would go on being held by the Wittelsbachs until the kingdom came to an end in 1918 . Most of Bavaria 's present - day borders were established after 1814 with the Treaty of Paris , in which Bavaria ceded Tyrol and Vorarlberg to the Austrian Empire while receiving Aschaffenburg and Würzburg .

In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names.  - Russia, also officially known as the Russian Empire, was a state that existed from 1721 until it was overthrown by the short-lived liberal February Revolution in 1917.

Princes of the German states gathered there to proclaim Wilhelm I of Prussia as German Emperor after the French capitulation in the Franco-Prussian War. Unofficially, the "de facto" transition of most of the German-speaking populations into a federated organization of states had been developing for some time through alliances formal and informal between princely rulersbut in fits and starts; self-interests of the various parties hampered the process over nearly a century of autocratic experimentation, beginning in the era of the Napoleonic Wars, which saw the dissolution of the Holy Roman Empire (1806), and the subsequent rise of German nationalism.  - The Soviet Union, officially the Union of Soviet Socialist Republics (USSR " ) was a socialist state in Eurasia that existed from 1922 to 1991.

The conflict was caused by Prussian ambitions to extend German unification and French fears of the shift in the European balance of power that would result if the Prussians succeeded. Some historians argue that the Prussian chancellor Otto von Bismarck deliberately provoked a French attack in order to draw the southern German statesBaden, Württemberg, Bavaria and Hesse-Darmstadtinto an alliance with the North German Confederation dominated by Prussia, while others contend that Bismarck did not plan anything and merely exploited the circumstances as they unfolded.
