High Quality Content by WIKIPEDIA articles! Bonn is the 19th largest city in Germany. Located in the Cologne/Bonn Region, about 20 kilometres south of Cologne on the river Rhine in the Federal State of North Rhine-Westphalia, it was the capital of West Germany from 1949 to 1990 and the official seat of government of united Germany from 1990 to 1999. Starting in 1998, many national government institutions were moved from Bonn to Berlin. Both houses of the German national parliament, the Bundestag as well as the Bundesrat, were moved along with the Chancellery and the residence of Germany head of state, the Bundesprà sident. Bonn remains a centre of politics and administration, however. Roughly half of all government jobs were retained as many government departments remained in Bonn and numerous sub-ministerial level government agencies relocated to the former capital from Berlin and other parts of Germany. In recognition of this, the former capital now holds the title of Federal City ("Bundesstadt").
