North Rhine-Westphalia (German: Nordrhein-Westfalen, pronounced [ˌnɔʁtʁaɪn vɛstˈfaːlən] (listen); Low Franconian: Noordrien-Wesfale; Low German: Noordrhien-Westfalen; Kölsch: Noodrhing-Wäßßfaale), commonly shortened to NRW (German: [ɛnʔɛʁˈveː] (listen)) in both written and spoken language, is the most populous of the 16 states of Germany.
North Rhine-Westphalia is located in Western Germany covering an area of 34,084 square kilometres (13,160 sq mi), which makes it the fourth-largest state. Apart from the city-states it is also the most densely populated German state. NRW has a population of 17.9 million making it the largest German state by population and features 30 of the 81 German municipalities with over 100,000 inhabitants, including Cologne (over 1 million), the state capital Düsseldorf, Dortmund and Essen (all about 600,000 inhabitants) and other cities predominantly located in the Rhine-Ruhr metropolitan area, the largest urban area in Germany and the third-largest on the European continent. The location of the Rhine-Ruhr at the heart of the European Blue Banana makes it well connected to other major European cities and metropolitan areas like the Randstad, the Flemish Diamond and the Frankfurt Rhine-Main Region.
North Rhine-Westphalia was established in 1946 after World War II from the Prussian provinces of Westphalia and the northern part of Rhine Province (North Rhine), and the Free State of Lippe by the British military administration in Allied-occupied Germany and became a state of the Federal Republic of Germany in 1949. The city of Bonn served as the federal capital until the reunification of Germany in 1990 and as the seat of government until 1999.
Culturally, North Rhine-Westphalia is not a uniform area; there are significant differences, especially in traditional customs, between the Rhineland region on the one hand and the regions of Westphalia and Lippe on the other. The state has always been Germany's powerhouse with the largest economy among the German states by GDP figures.
The state of North Rhine-Westphalia was established by the British military administration's "Operation Marriage" on 23 August 1946, by merging the province of Westphalia and the northern parts of the Rhine Province, both being political divisions of the former state of Prussia within the German Reich. On 21 January 1947, the former state of Lippe was merged with North Rhine-Westphalia. The constitution of North Rhine-Westphalia was then ratified through a referendum.
Main article: History of North Rhine-Westphalia
Main article: Rhineland
The first written account of the area was by its conqueror, Julius Caesar, the territories west of the Rhine were occupied by the Eburones and east of the Rhine he reported the Ubii (across from Cologne) and the Sugambri to their north. The Ubii and some other Germanic tribes such as the Cugerni were later settled on the west side of the Rhine in the Roman province of Germania Inferior. Julius Caesar conquered the tribes on the left bank, and Augustus established numerous fortified posts on the Rhine, but the Romans never succeeded in gaining a firm footing on the right bank, where the Sugambri neighboured several other tribes including the Tencteri and Usipetes. North of the Sigambri and the Rhine region were the Bructeri.
As the power of the Roman empire declined, many of these tribes came to be seen collectively as Ripuarian Franks and they pushed forward along both banks of the Rhine, and by the end of the fifth century had conquered all the lands that had formerly been under Roman influence. By the eighth century, the Frankish dominion was firmly established in western Germany and northern Gaul, but at the same time, to the north, Westphalia was being taken over by Saxons pushing south.
The Merovingian and Carolingian Franks eventually built an empire which controlled first their Ripuarian kin, and then the Saxons. On the division of the Carolingian Empire at the Treaty of Verdun, the part of the province to the east of the river fell to East Francia, while that to the west remained with the kingdom of Lotharingia.
By the time of Otto I (d. 973), both banks of the Rhine had become part of the Holy Roman Empire, and the Rhenish territory was divided between the duchies of Upper Lorraine on the Moselle and Lower Lorraine on the Meuse. The Ottonian dynasty had both Saxon and Frankish ancestry.
As the central power of the Holy Roman Emperor weakened, the Rhineland split into numerous small, independent, separate vicissitudes and special chronicles. The old Lotharingian divisions became obsolete, although the name survives for example in Lorraine in France, and throughout the Middle Ages and even into modern times, the nobility of these areas often sought to preserve the idea of a preeminent duke within Lotharingia, something claimed by the Dukes of Limburg, and the Dukes of Brabant. Such struggles as the War of the Limburg Succession therefore continued to create military and political links between what is now Rhineland-Westphalia and neighbouring Belgium and the Netherlands.
In spite of its dismembered condition and the sufferings it underwent at the hands of its French neighbours in various periods of warfare, the Rhenish territory prospered greatly and stood in the foremost rank of German culture and progress. Aachen was the place of coronation of the German emperors, and the ecclesiastical principalities of the Rhine bulked largely in German history.
Prussia first set foot on the Rhine in 1609 by the occupation of the Duchy of Cleves and about a century later Upper Guelders and Moers also became Prussian. At the peace of Basel in 1795, the whole of the left bank of the Rhine was resigned to France, and in 1806, the Rhenish princes all joined the Confederation of the Rhine.
After the Congress of Vienna, Prussia was awarded the entire Rhineland, which included the Grand Duchy of Berg, the ecclesiastic electorates of Trier and Cologne, the free cities of Aachen and Cologne, and nearly a hundred small lordships and abbeys. The Prussian Rhine province was formed in 1822 and Prussia had the tact to leave them in undisturbed possession of the liberal institutions to which they had become accustomed under the republican rule of the French. In 1920, the districts of Eupen and Malmedy were transferred to Belgium (see German-speaking Community of Belgium).
Main article: Westphalia
Around AD 1, numerous incursions occurred through Westphalia and perhaps even some permanent Roman or Romanized settlements. The Battle of Teutoburg Forest took place near Osnabrück and some of the Germanic tribes who fought at this battle came from the area of Westphalia. Charlemagne is thought to have spent considerable time in Paderborn and nearby parts. His Saxon Wars also partly took place in what is thought of as Westphalia today. Popular legends link his adversary Widukind to places near Detmold, Bielefeld, Lemgo, Osnabrück, and other places in Westphalia. Widukind was buried in Enger, which is also a subject of a legend.
Along with Eastphalia and Engern, Westphalia (Westfalahi) was originally a district of the Duchy of Saxony. In 1180, Westphalia was elevated to the rank of a duchy by Emperor Barbarossa. The Duchy of Westphalia comprised only a small area south of the Lippe River.
Parts of Westphalia came under Brandenburg-Prussian control during the 17th and 18th centuries, but most of it remained divided duchies and other feudal areas of power. The Peace of Westphalia of 1648, signed in Münster and Osnabrück, ended the Thirty Years' War. The concept of nation-state sovereignty resulting from the treaty became known as "Westphalian sovereignty".
As a result of the Protestant Reformation, there is no dominant religion in Westphalia. Catholicism and Lutheranism are on relatively equal footing. Lutheranism is strong in the eastern and northern parts with numerous free churches. Münster and especially Paderborn are thought of as Catholic. Osnabrück is divided almost equally between Catholicism and Protestantism.
After the defeat of the Prussian Army at the Battle of Jena-Auerstedt, the Treaty of Tilsit in 1807 made the Westphalian territories part of the Kingdom of Westphalia from 1807 to 1813. It was founded by Napoleon and was a French vassal state. This state only shared the name with the historical region; it contained only a relatively small part of Westphalia, consisting instead mostly of Hessian and Eastphalian regions.
After the Congress of Vienna, the Kingdom of Prussia received a large amount of territory in the Westphalian region and created the province of Westphalia in 1815. The northernmost portions of the former kingdom, including the town of Osnabrück, had become part of the states of Hanover and Oldenburg.
The flag of North Rhine-Westphalia is green-white-red with the combined coats of arms of the Rhineland (white line before green background, symbolizing the river Rhine), Westfalen (the white horse) and Lippe (the red rose). After the establishment of North Rhine-Westphalia in 1946, the tricolor was first introduced in 1948, but was not formally adopted until 1953. The plain variant of the tricolor is considered the civil flag and state ensign, while government authorities use the state flag (Landesdienstflagge) which is defaced with the state's coat of arms. The state ensign can easily be mistaken for a distressed flag of Hungary, as well as the former national flag of Iran (1964–1980). The same flag was used by the Rhenish Republic (1923–1924) as a symbol of independence and freedom.
According to legend, the horse in the Westphalian coat of arms is the horse that the Saxon leader Widukind rode after his baptism. Other theories attribute the horse to Henry the Lion. Some connect it with the Germanic rulers Hengist and Horsa.
North Rhine-Westphalia encompasses the plains of the Lower Rhine region and parts of the Central Uplands (die Mittelgebirge) up to the gorge of Porta Westfalica. The state covers an area of 34,083 km2 (13,160 sq mi) and shares borders with Belgium (Wallonia) in the southwest and the Netherlands (Limburg, Gelderland and Overijssel) in the west and northwest. It has borders with the German states of Lower Saxony to the north and northeast, Rhineland-Palatinate to the south and Hesse to the southeast.
Approximately half of the state is located in the relative low-lying terrain of the Westphalian Lowland and the Rhineland, both extending broadly into the North German Plain. A few isolated hill ranges are located within these lowlands, among them the Hohe Mark, the Beckum Hills, the Baumberge and the Stemmer Berge.
The terrain rises towards the south and in the east of the state into parts of Germany's Central Uplands. These hill ranges are the Weser Uplands – including the Egge Hills, the Wiehen Hills, the Wesergebirge and the Teutoburg Forest in the east, the Sauerland, the Bergisches Land, the Siegerland and the Siebengebirge in the south, as well as the left-Rhenish Eifel in the southwest of the state. The Rothaargebirge in the border region with Hesse rises to height of about 800 m above sea level. The highest of these mountains are the Langenberg, at 843.2 m above sea level, the Kahler Asten (840.7 m) and the Clemensberg (839.2 m).
The planimetrically-determined centre of North Rhine-Westphalia is located in the south of Dortmund-Aplerbeck in the Aplerbecker Mark (51° 28' N, 7° 33' Ö). Its westernmost point is situated near Selfkant close to the Dutch border, the easternmost near Höxter on the Weser. The southernmost point lies near Hellenthal in the Eifel region. The northernmost point is the NRW-Nordpunkt near Rahden in the northeast of the state. The Nordpunkt has located the only 100 km to the south of the North Sea coast. The deepest natural dip is arranged in the district Zyfflich in the city of Kranenburg with 9.2 m above sea level in the northwest of the state. Though, the deepest point overground results from mining. The open-pit Hambach reaches at Niederzier a deep of 293 m below sea level. At the same time, this is the deepest man-made dip in Germany.
The most important rivers flowing at least partially through North Rhine-Westphalia include: the Rhine, the Ruhr, the Ems, the Lippe, and the Weser. The Rhine is by far the most important river in North Rhine-Westphalia: it enters the state as Middle Rhine near Bad Honnef, where still being part of the Mittelrhein wine region. It changes into the Lower Rhine near Bad Godesberg and leaves North Rhine-Westphalia near Emmerich at a width of 730 metres. Almost immediately after entering the Netherlands, the Rhine splits into many branches.
The Pader, which flows entirely within the city of Paderborn, is considered Germany's shortest river.
For many, North Rhine-Westphalia is synonymous with industrial areas and urban agglomerations. However, the largest part of the state is used for agriculture (almost 52%) and forests (25%).

The state consists of five government regions (Regierungsbezirke), divided into 31 districts (Kreise) and 23 urban districts (kreisfreie Städte). In total, North Rhine-Westphalia has 396 municipalities (1997), including the urban districts, which are municipalities by themselves. The government regions have an assembly elected by the districts and municipalities, while the Landschaftsverband has a directly elected assembly.
The five government regions of North Rhine-Westphalia each belong to one of the two Landschaftsverbände:
|Landschaftsverband Rhineland||Landschaftsverband Westfalen-Lippe|| |
The regional authorities Rhineland (green) and
|Rural Districts (Kreise)||Urban Districts (Kreisfreie Städte)|
The state's area covers a maximum distance of 291 km from north to south, and 266 km from east to west. The total length of the state's borders is 1,645 km. The following countries and states have a border with North Rhine-Westphalia:
North Rhine-Westphalia has a population of approximately 17.5 million inhabitants (more than the entire former East Germany, and slightly more than the Netherlands) and is centred around the polycentric Rhine-Ruhr metropolitan region, which includes the industrial Ruhr region with the largest city of Dortmund and the Rhenish cities of Bonn, Cologne and Düsseldorf. 30 of the 80 largest cities in Germany are located within North Rhine-Westphalia. The state's capital is Düsseldorf; the state's largest city is Cologne. In 2015, there were 160,478 births and 204,373 deaths. The TRF reached 1.52 (2015) and was highest in Lippe (1.72) and lowest in Bochum (1.29).

The following table shows the population of the state since 1930. The values until 1960 are the average of the yearly population, from 1965 the population at year end is used.
As of 2018[update], 37.7% of the population of the state adhered to the Roman Catholic Church, 24.0% to the Evangelical Church in Germany and 38.4% of the population is irreligious or adheres to other religions.
North Rhine-Westphalia ranks first in population among German states for both Roman Catholics and Protestants.
In 2016, the interior ministry of North Rhine-Westphalia reported that the number of mosques with a salafist influence had risen from 30 to 55, which indicated both an actual increase and improved reporting. According to German authorities, Salafism is incompatible with the principles codified in the Constitution of Germany, in particular, democracy, the rule of law and a political order based on human rights.
Main article: Politics of North Rhine-Westphalia
The politics of North Rhine-Westphalia takes place within a framework of a federal parliamentary representative democratic republic. The two main parties are, as on the federal level, the centre-right Christian Democratic Union and the centre-left Social Democratic Party. From 1966 to 2005, North Rhine-Westphalia was continuously governed by the Social Democrats or SPD-led governments.
The state's legislative body is the Landtag ("state diet"). It may pass laws within the competency of the state, e.g. cultural matters, the education system, matters of internal security, i.e. the police, building supervision, health supervision and the media; as opposed to matters that are reserved to Federal law.
North Rhine-Westphalia uses the same electoral system as the Federal level in Germany: "Personalized proportional representation". Every five years the citizens of North Rhine-Westphalia vote in a general election to elect at least 181 members of the Landtag. Only parties who win at least 5% of the votes cast may be represented in parliament.
The Landtag, the parliamentary parties and groups consisting of at least 7 members of parliament have the right to table legal proposals to the Landtag for deliberation. The law that is passed by the Landtag is delivered to the Minister-President, who, together with the ministers involved, is required to sign it and announce it in the Law and Ordinance Gazette.
These are the Ministers-president of the Federal State of North-Rhine Westphalia:

Main article: Economy of North Rhine-Westphalia
In the 1950s and 1960s, Westphalia was known as Land von Kohle und Stahl (Land of Coal and Steel). In the post-World War II recovery, the Ruhr was one of the most important industrial regions in Europe, and contributed to the German Wirtschaftswunder. As of the late 1960s, repeated crises led to contractions of these industrial branches. On the other hand, producing sectors, particularly in mechanical engineering and metal and iron working industry, experienced substantial growth. Despite this structural change and an economic growth which was under national average, the 2018 GDP of 705 billion euro (1/4 of the total German GDP) made NRW the economically strongest state of Germany, as well as one of the most important economical areas in the world. Of Germany's top 100 corporations, 37 are based in North Rhine-Westphalia. On a per capita base, however, North Rhine-Westphalia remains one of the weaker among the Western German states.
North Rhine-Westphalia attracts companies from both Germany and abroad. In 2009, the state had the most foreign direct investments (FDI) anywhere in Germany. Around 13,100 foreign companies from the most important investment countries control their German or European operations from bases in North Rhine-Westphalia.
There have been many changes in the state's economy in recent times. Among the many changes in the economy, employment in the creative industries is up while the mining sector is employing fewer people. Industrial heritage sites are now workplaces for designers, artists and the advertising industry. The Ruhr region has – since the 1960s – undergone a significant structural change away from coal mining and steel industry. Many rural parts of Eastern Westphalia, Bergisches Land and the Lower Rhine ground their economy on "Hidden Champions" in various sectors.
As of June 2014, the unemployment rate is 8.2%, second highest among all western German states. In October 2018 the unemployment rate stood at 6.4% and was higher than the national average.
|Unemployment rate in %||9.2||8.8||9.2||10.0||10.2||12.0||11.4||9.5||8.5||8.9||8.7||8.1||8.1||8.3||8.2||8.0||7.7||7.4||6.8|
With its central location in the most important European economic area, high population density, strong urbanization and numerous business locations, North Rhine-Westphalia has one of the densest transport networks in the world.
The regional rail network is organised around the main in towns in Rhein-Ruhr: Bonn, Cologne, Wuppertal, Düsseldorf, Essen and Dortmund. Some public transport companies in this region are run under the umbrella of the Verkehrsverbund Rhein-Ruhr, which provides a uniform ticket system valid for the entire area. The Ruhr region is well-integrated into the national rail system, the Deutsche Bahn, for both passenger and goods services, each city in the region has at least one or more train stations. The bigger central stations have hourly direct connections to the bigger European cities as Amsterdam, Brussels, Paris, Vienna or Zürich.
The Rhein-Ruhr area also contains the longest tram system in the world, with tram and Stadtbahn services from Witten to Krefeld as well as the Rhine-Ruhr S-Bahn network. Originally the system was even bigger, it was possible to travel from Unna to Bad Honnef without using railway or bus services.
As of 2012[update], the VRR network consists of 978 lines, of which there are:
North Rhine-Westphalia has the densest network of Autobahns in Germany and similar Schnellstraßen (expressways). The Autobahn network is built in a grid network, with four east–west (A2, A40, A42, A44) and seven north–south (A1, A3, A43, A45, A52, A57, A59) routes. The A1, A2 and A3 are mostly used by through traffic, while the other autobahns have a more regional function.
Both the A44 and the A52 have several missing links, in various stages of planning. Some missing sections are currently in construction or planned to be constructed in the near future.
Additional expressways serve as bypasses and local routes, especially around Dortmund and Bochum. Due to the density of the autobahns and expressways, Bundesstraßen are less important for intercity traffic. The first Autobahns in the Region opened during the mid-1930s. Due to the density of the network, and the number of alternative routes, traffic volumes are generally lower than other major metropolitan areas in Europe. Traffic congestion is an everyday occurrence, but far less so than in the Randstad in the Netherlands, another polycentric urban area. Most important Autobahns have six lanes.
The region benefits from the presence of several airport infrastructure. The main airport is Düsseldorf Airport, world class, which hosts 24.5 million passengers per year and offers flights to many destinations.Düsseldorf is the third largest airport in Germany after Frankfurt and Munich; It is a hub for Eurowings and a focus city for several more airlines. The airport has three passenger terminals and two runways and can handle wide-body aircraft up to the Airbus A380.
The second airport is the international airport of Germany's fourth-largest city Cologne, and also serves Bonn, former capital of West Germany. With around 12.4 million passengers passing through it in 2017, it is the seventh-largest passenger airport in Germany and the third-largest in terms of cargo operations. By traffic units, which combines cargo and passengers, the airport is in fifth position in Germany. As of March 2015, Cologne Bonn Airport had services to 115 passenger destinations in 35 countries. It is named after Konrad Adenauer, a Cologne native and the first post-war Chancellor of West Germany.
Third airport in the region, Dortmund Airport is a minor international airport located 10 km (6.2 mi) east of Dortmund. It serves the eastern Rhine-Ruhr area, the largest urban agglomeration in Germany, and is mainly used for low-cost and leisure charter flights. In 2019 the airport served 2,719,563 passengers.
Then the airport of Münsterland Münster Osnabrück International Airport, hosting nearly 986,260 passengers per year and Airport Weeze with 693,404 passengers.
The Rhine flows through North Rhine-Westphalia. Its banks are usually heavily populated and industrialized, in particular the agglomerations Cologne, Düsseldorf and Ruhr area. Here the Rhine flows through the largest conurbation in Germany, the Rhine-Ruhr region. Duisburg Inner Harbour (Duisport) and Dortmund Port are large industrial inland ports and serve as hubs along the Rhine and the German inland water transport system. The country is crossed by many canals like Rhine–Herne Canal (RHK), der Wesel-Datteln-Kanal (WDK), der Datteln-Hamm-Kanal (DHK) and Dortmund-Ems-Kanal (DEK) an important role for inland navigation.
