State of Germany in the context of "South Baden"

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.

Saxony, officially the Free State of Saxony, is a landlocked state of Germany, bordering the states of Brandenburg, Saxony-Anhalt, Thuringia, and Bavaria, as well as the countries of Poland and the Czech Republic. Its capital is Dresden, and its largest city is Leipzig. Saxony is the tenth largest of Germany's sixteen states, with an area of 18,413 square kilometres (7,109 sq mi), and the seventh most populous, with more than 4 million inhabitants.

The term Saxony has been in use for more than a millennium. It was used for the medieval Duchy of Saxony, the Electorate of Saxony of the Holy Roman Empire, the Kingdom of Saxony, and twice for a republic. The first Free State of Saxony was established in 1918 as a constituent state of the Weimar Republic. After World War II, it was under Soviet occupation before it became part of communist East Germany and was abolished by the government in 1952. Following German reunification, the Free State of Saxony was reconstituted with enlarged borders in 1990 and became one of the five new states of the Federal Republic of Germany.

Martin Luther University Halle-Wittenberg (German: Martin-Luther-Universität Halle-Wittenberg), also referred to as MLU, is a public research university in the cities of Halle and Wittenberg. It is the largest and oldest university in the German state of Saxony-Anhalt. MLU offers German and international (English) courses leading to academic degrees such as BA, BSc, MA, MSc, doctoral degrees, and habilitation.

The university was created in 1817 through the merger of the University of Wittenberg (founded in 1502) and the University of Halle (founded in 1694). MLU is named after Protestant reformer Martin Luther, who was a professor in Wittenberg. Today, the university campus is located in Halle, while Leucorea Foundation in Wittenberg serves as MLU's convention centre.

Berlin is divided into boroughs or administrative districts (Verwaltungsbezirke). In Berlin, the term is officially shortened to Bezirke (districts). The boroughs are further divided into quarters (Ortsteile). These smaller localities are officially recognised, but have no administrative bodies of their own. Quarters and many of their subunits, the neighborhoods (Ortslagen), typically have strong identities that sometimes predate their inclusion into the modern boundaries of Berlin. Both the boroughs and the quarters function differently to other subdivisions in Germany due to Berlin's dual status as an independent city (kreisfreie Stadt) as well as a federated state of Germany (Land) in its own right.

Since 2001, Berlin has been made up of twelve boroughs, each with its own administrative body. However, because Berlin is a single municipality (Einheitsgemeinde), its boroughs have limited power, acting only as agencies of Berlin's state and city governments as laid out in the Greater Berlin Act of 1920. The boroughs are financially dependent on state donations, as they neither possess any taxation power nor own any property. This is in contrast to municipalities and counties in other German states, which are territorial corporations (Gebietskörperschaften) with autonomous functions and property.
