The Free Democrat Theodor Heuss was elected the first President of the Republic, and Adenauer was elected Chancellor (head of government) on 15 September 1949 with the support of his own CDU, the Christian Social Union, the liberal Free Democratic Party, and the right-wing German Party. It was said that Adenauer was elected Chancellor by the new German parliament by "a majority of one vote – his own". At age 73, it was thought that Adenauer would only be a caretaker Chancellor. However, he would go on to hold this post for 14 years, a period spanning most of the preliminary phase of the Cold War. During this period, the post-war division of Germany was consolidated with the establishment of two separate German states, the Federal Republic of Germany (West Germany) and the German Democratic Republic (East Germany).
