Abstract: | In the last two decades party membership numbers have declined in many parliamentary democracies, including in Germany. This article investigates how German parties have reacted to their losses, considering both the domestic and wider implications of their evolving responses. Their approaches include introducing multi-speed affiliation options, and providing new opportunities for members to affect party decisions. These changes are not unique to Germany, but they may have special meaning here, because the Federal Republic’s constitutional tradition treats membership-based political parties as key engines of representative democracy. The German parties’ experiences illustrate how membership losses can spur organisational experimentation, including in ways that have the potential to boost partisan political participation both within and around the parties. |
