This article is concerned with the relationship between the supporters of new social movements (peace, ecology, and anti‐nuclear power) and the Green Party in contemporary Germany. In theoretical terms the research interest lies in the question of the extent to which the new social movements in Germany are responsible for a change in the nature of the party system. Particular attention is given to the historical and electoral ties as well as the value system and the ideological orientation of the Green voters and the followers of new social movements. Their over‐all impact on future party system is still controversial: on the one hand, the Greens could prepare the way for a dealignment, and on the other hand they could determine the process of realignment within the German party system.
