The Federal City of Bonn ( German pronunciation: [ˈbɔn] ( listen ) ) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia , with a population of over 300,000. About 24 km (15 mi) south-southeast of Cologne , Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants.
Because of a political compromise following German reunification , the German state maintains a substantial presence in Bonn. Bonn is the secondary seat of the President , the Chancellor , the Bundesrat and the primary seat of six federal government ministries and twenty federal authorities. The unique title of Federal City ( German : Bundesstadt ) reflects its important political status within Germany. 
The headquarters of Deutsche Post DHL and Deutsche Telekom , both DAX-listed corporations, are in Bonn. The city is home to the University of Bonn and a total of 20 United Nations institutions, including headquarters for Secretariat of the UN Framework Convention Climate Change (UNFCCC), the Secretariat of the UN Convention to Combat Desertification (UNCCD), and the UN Volunteers programme.
