On 23 August 1946, the state of North Rhine-Westphalia was established by the British military administration under Decree No 46 “On the Abolition of the Provinces of the Former State of Prussia in the British Zone and Their Conversion into the Independent States". The territory of the state fell within the British Zone of Occupation and included the Ruhr and industrial Ruhr regions, as well as major cities of western Germany - Bonn, Bochum, Wuppertal, Dusseldorf, Solingen, Cologne, Münster, etc. The land would remain the most urbanised in the country until the 2020s.
There were several reasons for the establishment of the new. For one thing, the Allies were unanimous in their desire to destroy Prussian statehood. Furthermore, both Britain and the United States sought to establish economic life in the occupied territories, and the consolidation of territories under the local German self-administration was to facilitate this. The British military administration also sought to torpedo the French demand for the internationalisation of the Ruhr basin, which was supported by the USSR.
North Rhine-Westphalia would subsequently become a German state (land) when the German Parliamentary Council adopted the Basic Law for the Federal Republic of Germany (German Constitution) on 8 May 1949 and would be considered a federal state in the Federal Republic. The capital of the land would be the city of Düsseldorf.
