Uerdingen was originally a separate city, east of Krefeld and is over 1200 years old. First proved nomination was in 809. It got its charter as a city as early as 1255, well before Krefeld. In medieval times, Uerdingen was larger and more important than Krefeld. The city on the river Rhine had an inside harbor and merchandised because it was always the northest[clarification needed] enclave and customs office of the diocese of Cologne. In roman time (in the year 89), here was an attachment camp of the commander Marcus Hordeonius Flaccus (Castra Ordeonii). Perhaps the city is named to him but it is not proved.
In 1929 Uerdingen and Krefeld united in an specially form of City corporation with equal rights. The name of this city called “Krefeld-Uerdingen am Rhein” with two independent municipality in it. It was an roof community with two parts of town. This in Germany unique construction til today, was terminated from municipal ns-regime irregularly in April 1940 and named plainly Krefeld. After the second world war, the local politic injustice was corrected in slight parts only, what the people of Uerdingen annoyed.
Until the reapportionment and thereby specious justified, in the German state of North Rhine-Westphalia in 1975, Uerdingen, as a part of the city of Krefeld, had an unusual special status within Germany. The former Rhine city had some special rights and privileges. One sign of this can still be seen today in Krefeld's city coat of arms (“Wappen”), which still has the Uerdinger arms in its right half.
The most important employers in Uerdingen, as well in Krefeld the last fifth decades was the Bayer concern, which has its second largest plant here. In 2004 most of the chemical and approximately a third of synthetics activities were spun off from Bayer AG. Now it is an chemical area with all companies outside of Bayer AG. In the area also there is the rail car manufacturer Waggonfabrik Uerdingen, DUEWAG today SIEMENS/Alsthom. This factory produced, among other, the famous ICE-trains for international fleets. Behind the “Uerdinger” brand of gin and Dujardin Cognac made by Melchers distillery, Uerdingen is best known for its tradition-steeped football team F.C. Bayer 05 Uerdingen, now known as KFC Uerdingen 05. The soccer-team plays in the 3. Liga of Germany an was in 1985 winner of the legendary DFB-Pokal against Bayern Munich in Berlin. Landmark of Uerdingen is the known bridge over the river Rhine, built in 1936 and monument since 1987.
Uerdingen is bounded on its west by the Krefeld city districts of Bockum, Gartenstadt, and Elfrath; on the northwest by Traar; on the north by Duisburg-Rumeln-Kaldenhausen; and on the northeast by Hohenbudberg in the direction of Duisburg-Rheinhausen. To the east of Uerdingen, across the Rhine, lies Duisburg-Mündelheim, and on the south lies the Krefeld city district of Linn.
The arms of Uerdingen show the golden keys of Saint Peter upon a divided background, blue above and red below. Blue and red are said to be the colors of Saint Peter, whereby blue would be said to represent heaven and red to symbolize hell. The colors of Uerdingen are likewise blue and red.
A dialect of Low German is still spoken in Uerdingen, a variety known locally as “Oedingsch Platt,” oedingsch signifying “of Uerdingen” in the dialect, and Platt being a northern German term for the varieties of Low German in general. Oedisch Platt should not be confused with Krieewelsch Platt, the Krefeld Platt variety of Low German, as there are small, subtle differences between the two. The best known Uerdingen song in Platt is “Oeding blievt Oeding (os Städtche am Rhien)” by Andreas Otto Kickers, sometimes considered to be the Uerdinger Hymn. The song describes life and history of the city and of its inhabitants. The “Rhienstädter” sing this at all occasions, and thereby cultivate the local Oedingsch Platt dialect a bit longer. At the northeastern edge of the city runs the isogloss known as the Uerdingen Line.
Uerdingen voters after World War II were overwhelmingly inclined towards the SPD, the Social Democratic Union. At both of the most recent municipal elections, however, the CDU, the Christian Democratic Union, received the most votes.
Uerdingen accounts for the largest part of the Bezirksvertretung Uerdingen (“District Representation of Uerdingen”), but the area of the electoral district reaches beyond Uerdingen proper.

The economic life of Uerdingen is dominated by the large chemical plants of Bayer AG, which produce synthetics, pigments, and chemical feedstock here. Another important branch of local industry is the assembly of vehicles. The vehicle producer Uerdingen Waggonfabirk, founded in 1898, later a part of DUEWAG, produced here the Uerdingen railbus, a type of light locomotive largely for passenger service on side rail lines. The plant today belongs to Siemens Transportation Systems. The name “Waggonfabrik,” referring to the Uerdinger Waggonfabrik works, still comes up in everyday conversation among locals.
