Bonn in the context of "Rhine-Ruhr"

Geneva (/dʒɪˈniːvə/ jin-EE-və, Arpitan: [dzəˈnɛva] ; French: Genève [ʒ(ə)nɛv] ) is the second-most populous city in Switzerland and the most populous in French-speaking Romandy. Situated in the southwest of the country, where the Rhône exits Lake Geneva, it is the capital of the Republic and Canton of Geneva. Geneva is a global city, an international financial centre, and a worldwide centre for diplomacy, which has led to it being called the "Peace Capital".

It hosts the highest number of international organizations in the world, including the headquarters of many agencies of the United Nations and the ICRC and IFRC of the Red Cross. It was where the Geneva Conventions on humanitarian treatment in war were signed, and, in the aftermath of World War I, it hosted the League of Nations. It shares a unique distinction with municipalities such as New York City, Bonn, Basel, and Strasbourg as a city which serves as the headquarters of at least one critical international organization without being the capital of a country.

The Electorate of Cologne (German: Kurfürstentum Köln), sometimes referred to as Electoral Cologne (German: Kurköln), was an ecclesiastical principality of the Holy Roman Empire that existed from the 10th to the early 19th century. It consisted of the Hochstift—the temporal possessions—of the archbishop of Cologne, and was ruled by him in his capacity as prince-elector. There were only two other ecclesiastical prince-electors in the Empire: the Electorate of Mainz and the Electorate of Trier. The archbishop-elector of Cologne was also arch-chancellor of Italy (one of the three component titular kingdoms of the Holy Roman Empire, the other two being Germany and Burgundy) and, as such, ranked second among all ecclesiastical and secular princes of the Empire, after the archbishop-elector of Mainz, and before that of Trier.

The capital of the electorate was Cologne. Conflicts with the citizens of Cologne caused the elector to move to Bonn. The Free Imperial City of Cologne was recognized after 1475, thus removing it from even the nominal secular authority of the elector. Cologne and Bonn were occupied by France in 1794. The right bank territories of the electorate were secularized in 1803 during the German mediatization.

Cologne (/kə.ˈloʊn/ kə-LOHN; German: Köln [kœln] ; Kölsch: Kölle [ˈkœ̂lə] ) is the fourth-most populous city of Germany and the largest city of the German state of North Rhine-Westphalia with nearly 1.1 million inhabitants in the city proper and over 3.1 million people in the Cologne Bonn urban region. Cologne is also part of the Rhine-Ruhr metropolitan region, the second biggest metropolitan region by GDP in the European Union. Centered on the left bank of the Rhine, Cologne is located on the River Rhine (Lower Rhine), about 35 kilometres (22 mi) southeast of the North Rhine-Westphalia state capital Düsseldorf and 22 kilometres (14 mi) northwest of Bonn, the former capital of West Germany.

The city's medieval Cologne Cathedral (Kölner Dom) was the world's tallest building from 1880 to 1890 and is today the third-tallest church and tallest cathedral in the world. It was constructed to house the Shrine of the Three Kings and is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne. Cologne is famous for Eau de Cologne, which has been produced in the city since 1709; "cologne" has since come to be a generic term.

Düsseldorf (German: [ˈdʏsl̩dɔʁf] ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state after Cologne and the sixth-largest city in Germany, with a 2024 population of 618,685. Most of Düsseldorf lies on the right bank of the Rhine, and the city has grown together with Neuss, Ratingen, Meerbusch, Erkrath and Monheim. Düsseldorf is the central city of Rhine-Ruhr, the second biggest metropolitan region by GDP in the European Union, that stretches from Bonn via Cologne and Düsseldorf to the Ruhr.

Düsseldorf began as a small settlement at the mouth of the Düssel River, gaining city rights in 1288 after the Battle of Worringen. In the Late Middle Ages and Renaissance, it grew into a regional political and cultural centre under the Dukes of Berg and later as the capital of the United Duchies of Jülich-Cleves-Berg. The 17th and 18th centuries saw flourishing arts and architecture, with Düsseldorf becoming known for its court culture and early art academy. During the Napoleonic era, it was briefly part of the Grand Duchy of Berg before coming under Prussian control in 1815, where it industrialised rapidly in the 19th century. During the 20th century, Düsseldorf developed into one of Germany’s most important centres for administration, business, and culture. In 1946, it became the capital of the newly created state of North Rhine-Westphalia, strengthening its political role.

West Germany was the common English name for the Federal Republic of Germany (FRG) from its formation on 23 May 1949 until its reunification with East Germany on 3 October 1990. It was sometimes known as the Bonn Republic after its capital city of Bonn, or as the Second German Republic. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from twelve states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France.

At the onset of the Cold War, Europe was divided between the Western and Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as the sole democratically reorganised continuation of the 1871–1945 German Reich.

The University of Bonn, officially the Rhenish Friedrich Wilhelm University of Bonn (German: Rheinische Friedrich-Wilhelms-Universität Bonn), is a public research university in Bonn, North Rhine-Westphalia, Germany. It was founded in its present form as the Rhein-Universität (English: Rhine University) on 18 October 1818 by Frederick William III, as the linear successor of the Kurkölnische Akademie Bonn (English: Academy of the Prince-elector of Cologne) which was founded in 1777. The University of Bonn offers many undergraduate and graduate programs in a range of subjects and has 544 professors. The University of Bonn is a member of the German U15 association of major research-intensive universities in Germany and has the title of "University of Excellence" under the German Universities Excellence Initiative.

Bonn has 6 Clusters of Excellence, the most of any German university; the Hausdorff Center for Mathematics, the Matter and Light for Quantum Computing cluster, Bonn Center for Dependency and Slavery Studies, PhenoRob: Research for the Future of Crop Production, the Immune Sensory System cluster, and ECONtribute: Markets and Public Policy. The University and State Library Bonn (ULB Bonn) is the central university and archive library of the Rheinische Friedrich-Wilhelms-Universität Bonn and North Rhine-Westphalia; it holds more than five million volumes.

The capital of Germany is the city of Berlin. It is the seat of the Federal President of Germany, whose official residence is Bellevue Castle. The Federal Council is the representation of the Lands of Germany and has its seat at the former Prussian House of Lords. Though most of the ministries are seated in Berlin, some of them, as well as some minor departments, are seated in Bonn, the former capital of West Germany. Although Berlin is officially the capital of Germany, 8,000 out of the 18,000 total officials employed at the federal bureaucracy still work in Bonn, about 600 km (370 mi) away from Berlin.
