In the controversial selection for a "provisional capital" of the Federal Republic of Germany, Adenauer championed Bonn over Frankfurt am Main. The British had agreed to detach Bonn from their zone of occupation and convert the area to an autonomous region wholly under German sovereignty; the Americans were not prepared to grant the same for Frankfurt. He also resisted the claims of Heidelberg, which had better communications and had survived the war in better condition; partly because the Nazis had been popular there before they came to power and partly, as he said, because the world would not take them seriously if they set up their state in the city of The Student Prince.
