In 1989-1990, peaceful protests shook the German Democratic Republic (GDR), ushered in unification, and provided a powerful narrative of people power that would shape protest movements for decades to come. This article surveys eastern German protest across three decades, exploring the interplay of protest voting, demonstrations, and protest parties since the Wende. It finds that protest voting in the east has had a significant political impact, benefiting and shaping parties on both the left and the right of the party spectrum. To understand this potential, it examines how economic and political factors, although changing, have continued to provide favorable conditions for political protest in the east. At particular junctures, waves of protest occurred in each of the three decades after unification, shaping the party landscape in Germany.
