German Emperor in the context of "Ernst von Ihne"

The German Empire (German: Deutsches Reich), also referred to as Imperial Germany, the Second Reich, or simply Germany, was the period of the German Reich from the unification of Germany in 1871 until the November Revolution in 1918, when Germany changed its form of government to a republic. The German Empire consisted of 25 states, each with its own nobility: four constituent kingdoms, six grand duchies, five duchies (six before 1876), seven principalities, three free Hanseatic cities, and one imperial territory. While Prussia was only one of the four kingdoms in the realm, it contained about two-thirds of the Empire's population and territory, and Prussian dominance was also constitutionally established, since the King of Prussia was also the German Emperor (Deutscher Kaiser).

The empire was founded on 18 January 1871, when the south German states, except for Austria, Switzerland and Liechtenstein, joined the North German Confederation. The new constitution came into force on 16 April, changing the name of the federal state to the German Empire and introducing the title of German Emperor for Wilhelm I, King of Prussia from the House of Hohenzollern. Berlin remained its capital, and Otto von Bismarck, Minister President of Prussia, became chancellor, the head of government. After 1850, the states of Germany had rapidly become industrialized. In 1871, Germany had a population of 41 million people; by 1913, this had increased to 68 million. A heavily rural collection of states in 1815, the now united Germany became predominantly urban. German factories were often larger and more modern than many of their British and French counterparts, but the preindustrial sector was more backward. The success of the German Empire in the natural sciences was such that one-third of all Nobel Prizes went to German inventors and researchers. During its 47 years of existence, the German Empire became an industrial, technological, and scientific power in Europe, and by 1913, Germany was the largest economy in continental Europe and the third largest in the world. Germany also became a great power, building the longest railway network of Europe, the world's strongest army, and a fast-growing industrial base. Starting very small in 1871, in a decade, the navy became second only to Britain's Royal Navy.

The Constitution of the German Empire (German: Verfassung des Deutschen Reiches) was the basic law of the German Empire. It came into effect on 4 May 1871 and lasted formally until 14 August 1919. Some German historians refer to it as Bismarck's imperial constitution (German: Bismarcksche Reichsverfassung, BRV).

The Constitution created a federation (federally organised national state) of 25 German states under the permanent presidency of Prussia, the largest and most powerful of the states. The presidency (Bundespräsidium) was a hereditary office of the King of Prussia, who had the title of German Emperor. The emperor appointed the chancellor, who was the head of government and chairman of the Bundesrat, the council of representatives of the German states. Laws were enacted by the Bundesrat and the Reichstag, the parliament elected by male Germans above the age of 25 years.

The proclamation of the German Empire, also known as the Deutsche Reichsgründung, took place on January 18, 1871 after the joint victory of the German states in the Franco-Prussian War. As a result of the November Treaties of 1870, the southern German states of Baden, Hesse-Darmstadt, with their territories south of the Main line, Württemberg and Bavaria, joined the Prussian-dominated "North German Confederation" on 1 January 1871. On the same day, the new Constitution of the German Confederation came into force, thereby significantly extending the federal German lands to the newly created German Empire. The Day of the founding of the German Empire, January 18, became a day of celebration, marking when the Prussian King William I was proclaimed German Emperor at the Palace of Versailles, outside Paris, France.

Wilhelm I (William I; William Frederick Louis; German: Wilhelm Friedrich Ludwig; 22 March 1797 – 9 March 1888) was King of Prussia from 1861 and German Emperor from 1871 until his death in 1888. A member of the House of Hohenzollern, he was the first head of state of a united Germany. He was regent of Prussia from 1858 to 1861 for his elder brother, King Frederick William IV. During the reign of his grandson Wilhelm II, he was known as Emperor Wilhelm the Great (German: Kaiser Wilhelm der Große).

The second son of Prince Frederick William and Louise of Mecklenburg-Strelitz, Wilhelm was not expected to ascend to the throne. His grandfather, King Frederick William II died the year he was born, and his father was crowned Frederick William III. Wilhelm fought with distinction during the War of the Sixth Coalition, and afterwards became a prominent figure within the Prussian Army. In 1840, his childless elder brother became King of Prussia, making him heir presumptive. Wilhelm played a major role in crushing the Revolutions of 1848 in Germany, although he was briefly forced into exile in England. Frederick William IV suffered a stroke in 1857 and was left incapacitated, and Wilhelm was formally named Prince Regent a year later. In 1861, Wilhelm ascended to the Prussian throne on his elder brother's death.

Wilhelm II (English: Frederick William Victor Albert; German: Friedrich Wilhelm Viktor Albert; 27 January 1859 – 4 June 1941) was the last German Emperor and King of Prussia from 1888 until his abdication in 1918. His fall from power marked the end of the German Empire as well as the Hohenzollern dynasty's 500-year rule over Prussia and its predecessor state, Brandenburg.

Born during the reign of his granduncle Frederick William IV of Prussia, Wilhelm was the son of Prince Frederick William and Victoria, Princess Royal. Through his mother, he was the eldest of the 42 grandchildren of Queen Victoria of the United Kingdom. In March 1888, Wilhelm's father, Frederick William, ascended the German and Prussian thrones as Frederick III. Frederick died just 99 days later, and his son succeeded him as Wilhelm II.

The abdication of Wilhelm II as German Emperor and King of Prussia was declared unilaterally by Chancellor Max von Baden at the height of the German revolution on 9 November 1918, two days before the end of World War I. It was formally affirmed by a written statement from Wilhelm on 28 November while he was in exile in Amerongen, the Netherlands. The abdication ended the House of Hohenzollern's 300-year rule over Prussia and 500-year rule over its predecessor state, Brandenburg. With the loss of the monarchical legitimacy that was embodied by the emperor, the rulers of the Empire's 22 monarchical states also relinquished their royal titles and domains.

Wilhelm's abdication was triggered by Germany's impending defeat in World War I. In an attempt to obtain better terms from the Allies, a number of changes were made in the government and the constitution to partially democratise the Empire. The political changes were not enough to satisfy US President Woodrow Wilson, who was leading the attempt to broker an armistice. When it became clear that he wanted Wilhelm to abdicate, both the military and the government began to make various plans to save the monarchy through a regency or some other means after Wilhelm stepped down. The outbreak of the German revolution in the first days of November 1918 increased the pressure on Wilhelm to abdicate, but he continued to refuse. In order to calm the volatile situation in Berlin, Chancellor Baden, without Wilhelm's knowledge or approval, announced on 9 November that the Emperor had abdicated. Later that afternoon, Germany was proclaimed a republic, and Wilhelm went into exile in the Netherlands the next day. His official abdication came on 28 November. The 500-year-old Hohenzollern dynasty ended quietly, with almost no violence or fanfare.

The chancellor of Germany is the political leader of Germany and the head of the federal government. The office holder is responsible for selecting all other members of the government and chairing cabinet meetings.

The office was created in the North German Confederation in 1867, when Otto von Bismarck became the first chancellor. With the unification of Germany and establishment of the German Empire in 1871, the Confederation evolved into a German nation-state and its leader became known as the chancellor of Germany. Originally, the chancellor was only responsible to the emperor. This changed with the constitutional reform in 1918, when the Parliament was given the right to dismiss the chancellor. Under the 1919 Weimar Constitution the chancellors were appointed by the directly elected president, but were responsible to Parliament.

Potsdam (German pronunciation: [ˈpɔtsdam] ) is the capital and largest city of the German state of Brandenburg. It is part of the Berlin/Brandenburg Metropolitan Region. Potsdam sits on the River Havel, a tributary of the Elbe, downstream of Berlin, and lies embedded in a hilly morainic landscape dotted with many lakes, around 20 of which are located within Potsdam's city limits. It lies some 25 kilometres (16 miles) southwest of Berlin's city centre. The name of the city and of many of its boroughs are of Slavic origin.

Potsdam was a residence of the Prussian kings and the German Emperor until 1918. Its planning embodied ideas of the Age of Enlightenment: through a careful balance of architecture and landscape, Potsdam was intended as "a picturesque, pastoral dream" which would remind its residents of their relationship with nature and reason.
