Roman period and Middle Ages[edit]
Remains of the city wall
Duisburg developed at the confluence of the Ruhr and the Rhine, on the outer bank of the Rhine and at the western end of the Hellweg trade route. Continuous settlement in the city's core area can be traced from the 1st century, initially Roman and from the 5th century onward Frankish.
In 420, the Franks seized the former Roman settlement and recolonised it. By the 8th century, a Frankish–Carolingian royal estate had been established, which later developed into a palatinate. Duisburg was first mentioned in 883 as Diusburh, when Norman raiders captured the settlement and remained there over the winter.
Due to the town's favorable geographic position a count palatine was established and the town was soon granted the royal charter of a free imperial city. Duisburg became a member of the Hanseatic League. Around 1000 the river Rhine moved westward from the town. This put an end to the Duisburg's development as a trading town and it soon transformed into a predominantly agrarian settlement.
Construction of the city walls began in 1120, and the city charter was granted by King Lothar III in 1279. By 1290, Duisburg had become part of the County (and, after 1417, the Duchy) of Cleves. In 1445, an attack by Archbishop-Elector Dietrich II. von Moers [de] of the Electorate of Cologne was successfully repelled.
Early modern period[edit]
Corputius plan of Duisburg, completed in 1566
The Reformation spread to Duisburg only gradually around the mid-16th century. Refugees from the Netherlands and England contributed to the city's increasing Calvinist orientation. In 1566, Johannes Corputius completed his city map of Duisburg.
In September 1610, delegates meeting in Duisburg's Saviour's Church [de] at the first General Synod of the Reformed congregations of Jülich-Cleves-Berg established a common church order based on the presbyterial-synodal principle, an institutional foundation that shaped the later Reformed Church on the Lower Rhine.
As a result of the Treaty of Xanten of 1614, the Duchy of Cleves passed to the House of Hohenzollern of Brandenburg. The city's reputation as "Educated Duisburg" ("Duisburgum Doctum") was established through the work of cartographer Gerardus Mercator and the founding of the University of Duisburg by Frederick William I of Brandenburg in 1655.
By 1666 the city, still within the Duchy of Cleves, became incorporated into Brandenburg-Prussia. In 1672, Frederick William joined the Franco-Dutch War as an ally of the Dutch Republic. A French military plan of Duisburg was prepared during the opening phase of the war. The plan showed the city's fortifications, roads, surrounding fields, waterways, and a geographical notice, and was preserved among French military correspondence for the campaign.
The city's commercial activity revived in 1674 with the establishment of a regular shipping route to the Netherlands. Trade, particularly in colonial goods, led to the development of a significant freight forwarding industry, as well as textile, tobacco, and sugar factories, which became the city's most important economic sectors.
Industrial revolution[edit]
The rise of tobacco and textile industries in the 18th century made Duisburg an industrial center. Big industrial companies such as iron and steel producing firms (Thyssen and Krupp) influenced the development of the city within the Prussian Rhine Province.
Large housing areas near production sites were being built as workers and their families moved in.
In 1823, a district (Landkreis) of Duisburg was established, encompassing the neighboring cities of Essen and Mülheim an der Ruhr. The following year, in 1824, the construction of the sulfuric acid factory Fr. W. Curtius marked the beginning of the industrial era in Duisburg. With the construction of a canal connecting the city to the Rhine beginning in 1826, Rhine trade regained considerable importance. In 1828, Franz Haniel [de] founded a dockyard for steamships, further contributing to the city's economic development. From 1844 onward, the connection to the Ruhr enabled Duisburg to participate in the growing coal trade. As the port expanded to handle timber, ore, and especially grain, Duisburg's port became the second-largest Rhine port after Ruhrort.
The Port of Duisburg in 1931
Duisburg's connection to the expanding railway network began in the 1840s, with the railway line to Düsseldorf completed in 1846, followed by the railway line via Dortmund to Minden in 1847. The city became an independent city borough in 1873. In 1904, it celebrated the birth of its 100,000th resident, Ernst R. Straube. Increasing competition between the ports of Duisburg and Ruhrort led, in 1905, to the merger of the ports, followed soon after by the unification of the cities of Duisburg, Ruhrort, and Meiderich.
On 8 March 1921, French infantry occupied Duisburg to secure war reparation payments incurred during World War I. In 1929, Duisburg was merged with the neighboring city of Hamborn to form the new city of Duisburg-Hamborn. This name was later shortened to Duisburg in 1935.
In November 1938, during the Kristallnacht pogroms organized by the Nazis, the city's synagogue was destroyed.
World War II[edit]
Main article: Bombing of Duisburg in World War II
A major logistical center in the Ruhr and location of chemical, steel and iron industries, Duisburg was a primary target of Allied bombers, with industrial areas and residential blocks targeted by Allied incendiary bombs.
On the night of 12–13 June 1941, British bombers dropped a total of 445 tons of bombs in and around Duisburg. As part of the Battle of the Ruhr, another British raid of 577 bombers destroyed the old city between 12 and 13 May 1943 with 1,599 tons of bombs. During the bombing raids, 96,000 people were made homeless with countless lives lost.
In 1944, the city was again badly damaged as a total of 2,000 tons of bombs were dropped on 22 May. On 14 October, the tonnage was repeated with 2,018 tons when Halifax, Lancaster, and Mosquito bombers appeared over Duisburg as part of Operation Hurricane. This daylight raid was followed by a night attack; over 24 hours about 9,000 tons of HE and incendiaries had been dropped on Duisburg. Numerous similar attacks followed until the end of 1944.
The Allied ground advance into Germany reached Duisburg in April 1945. The US 17th Airborne Division, acting as regular infantry and not in a parachute role, met only scattered resistance in the vicinity and captured the city on 12 April 1945.
On 8 May 1945, the ADSEC Engineer Group A, led by Col. Helmer Swenholt, commanding officer of the 332nd Engineer General Service Regiment, constructed a railway bridge between Duisburg and Rheinhausen across the Rhine. It was 860 metres (2,820 ft) long, and constructed in six days, fifteen hours and twenty minutes, a record time. It was named the "Victory Bridge".
Federal Republic of Germany[edit]
Memorial to the victims of the Love Parade disaster
A total of 299 bombing raids had almost completely destroyed the historic cityscape. 80% of all residential buildings had been destroyed or partly damaged.[citation needed] Almost the whole of the city had to be rebuilt, and most historic landmarks had been lost.[citation needed]
Beginning in the mid-1960s, the decline of Duisburg's steel and mining industry caused a significant loss of residents. While in 1975 approximately 590,000 people were living in Duisburg, the number had shrunk to 518,000 in 1985.
Duisburg celebrated its 1100th anniversary in 1983. The city's population recovered a little in the following years, up to 537,000 in 1992. It declined to 488,000 in 2011. On 19 July 2004, it was hit by a tornado. The municipal theater and parts of the city center were damaged. The city hosted the 7th World Games in 2005. In 2010, 21 people died because of a mass panic at the Love Parade; over 500 people were injured.
In March 2011, the inaugural freight train of the Chongqing–Xinjiang–Europe Railway arrived in Duisburg and since then the city has served as the railway's western terminus.
On 7 April 2025 15 schools were closed after an unknown far right extremist sent multiple bomb threats.
