Rivalry between Cologne and DüsseldorfRivalry between Cologne and Düsseldorf, two major cities in the Rhineland, Germany, apart on the Rhine, is now mostly on a sporting and cultural level, but based on historical and economic factors. Cologne was a Roman colony, and later a Free Imperial City, while Düsseldorf, a small medieval settlement, is now the capital of the state of North Rhine-Westphalia. The root of the enmity between the two cities is commonly cited as the Battle of Worringen on 5 June 1288, which, however, is to be regarded as "legend".
