The article is a synthetic outlook at Konrad Adenauer’s life, activity and the legacy of that politician, described in a tendentious way in the past period, and nowadays – after a temporary increase in the interest during the first years of systemic transformation – deserving a closer examination. In the initial part of the article, some integration concepts of past centuries have been outlined. Then, in a biographical sketch, Adenauer’s private and public activities were characterized, falling into diverse political periods, ranging from imperial Germany, to the post-war formation of the foundations of a reborn democratic state. His participation in these events is outlined. The main achievements of Adenauer during almost 30 years of work in the Cologne municipality are pointed out and the repressions he suffered during the Nazi regime and his participation in the post-war reconstruction of Germany were discussed: long-term leadership in the CDU and the 14-year period of government as the first chancellor of democratic post-war Germany. It was pointed out that the political line he designated, the active presence of Germany in the uniting Europe, proved to be very stable and continued by his successive successors.
