In the 1980's the West Germany party system finds itself in a new stage of development which bodes well for the continued long-term development of the second republic. Drawing on research from the comparative historical development of party systems and democratic regimes as well as from analysis of the recent elections, it is suggested that the concentration process in the party system of 1949–1983 has evolved into a more dispersed pattern with predominantly positive consequences for the Bonn democracy. The rise of the Greens, the gradual decline of the SPD, and the center-right coalition of CDU/CSU/FDP are analyzed from the standpoint of their contribution to stable and effective democracy. The nature of the coalition dynamics on both sides of the right-left spectrum are discussed with the conclusion that while West Germany is predominantly a Parteiendemokratie, the new forms of participation, the further development of pluralism, and the increased competition of ideas make it a democracy governed essentially by parliamentary parties yet more responsive to extraparliamentary forces.
