Düsseldorf is one of the five Regierungsbezirke of North Rhine-Westphalia, Germany, located in the north-west of the country. It covers the western part of the Ruhr Area, as well as the Niederrheinische Tiefebene, the lower Rhine area. It is the most populated of all German administrative areas of the kind. It is the only area in Germany where the traditional dialects are Low Franconian, rather than Low German or High German.
