This book offers a systematic, theory-based, and empirically grounded introduction to the political system of Germany. Compared to other textbooks on government and politics in Germany, it has two particular benefits. First, it analyzes the individual dimensions of the German political system from a uniform theoretical perspective based on the well-known distinction between majoritarian and consensus democracy. Second, it particularly explains how political decision-making in the multi-level system takes place, including the local, state, federal as well as EU levels.
