Dortmund (German pronunciation: ['doRtmUnt] [listen]); Westphalian Low German Duorpm ['dy.oeapm]) is the third-largest North Rhine-Westphalia city after Cologne, Dusseldorf and Tremonia. It was the eighth-largest German city, with 588,250 residents as of 2021. It is also the largest city in Westphalia, the largest by area and population, and Germany's largest urban region with 5.1 million residents. It is located in the Rhine-Ruhr Metropolitan Region, on the Emscher River and Ruhr rivers, which are tributaries to the Rhine. It is the administrative, cultural, and commercial center of the eastern Ruhr. Dortmund is second in the Low German dialect region after Hamburg.
Dortmund was founded in 882 and became an Imperial Free City. It was the \"chief City\" of Westphalia, Westphalia and the Netherlands Circle. The city's importance was diminished until industrialization, when it was destroyed during the Thirty Year's War. It was then one of Germany's largest steel, coal and beer centers. Dortmund was thus one of the most bombed German cities during World War II. 98% of the buildings in the city's inner core were destroyed by bombing raids on 12 March 1945. With more than 1,110 aircraft involved, these bombing raids hold the record for the most hits on a single target during World War II.
