How Adenauer Lost Power: Understanding Leadership Rivalry and Succession Conflict in Political Parties

In this article, we reconstruct and interpret the Adenauer–Erhard leadership rivalry in the CDU. This leadership struggle culminated in Erhard replacing Adenauer in 1963 and Adenauer's continued ‘guerrilla’ warfare against Erhard's leadership, which was one of the contributing factors to the brevity of Erhard's tenure. The case is of intrinsic historical interest but also provides a muster for recent and ongoing leadership succession predicaments in governing parties in Germany and elsewhere. The article presents a conceptual framework of party leadership succession, and zooms in on the (mis)match between the tactical choices made by the incumbent leader and key succession candidates as a key factor explaining the nature and impact of successions. The framework is then applied to the case, and the implications of the findings are placed in a broader comparative context.
