On each of the six leaders profiled in this book, these upheavals left an indelible mark. The political career of Konrad Adenauer (born 1876), who served as mayor of Cologne from 1917 to 1933, would include the interwar conflict with France over the Rhineland as well as the rise of Hitler; during the Second World War, he was twice imprisoned by the Nazis. Beginning in 1949, Adenauer shepherded Germany past the lowest point of its history by abandoning its decades-long quest for domination of Europe, anchoring Germany in the Atlantic Alliance, and rebuilding it on a moral foundation which reflected his own Christian values and democratic convictions.
