Born in 1930 in Ludwigshafen to a Roman Catholic family, Kohl joined the Christian Democratic Union in 1946 at the age of 16. He earned a PhD in history at Heidelberg University in 1958, and worked as a business executive before becoming a full-time politician. He was elected as the youngest member of the Parliament of Rhineland-Palatinate in 1959 and from 1969 to 1976 was minister president of the Rhineland-Palatinate state. Viewed during the 1960s and the early 1970s as a progressive within the CDU, he was elected national chairman of the party in 1973. After he had become party leader, Kohl was increasingly seen as a more conservative figure. In the 1976 and 1980 federal elections his party performed well, but the social-liberal government of social democrat Helmut Schmidt was able to remain in power. After Schmidt had lost the support of the liberal FDP in 1982, Kohl was elected Chancellor, forming a coalition government with the FDP. Kohl chaired the Group of Seven in 1985 and 1992.
