Stadtstaat

Stadtstaat is a political designation for a state whose territory consists of a single city and its immediate surroundings, rather than a larger region containing multiple cities. The term is most often used in a German context to describe a city that also functions as a federal state.

Etymology and concept: The word combines Stadt (city) and Staat (state). In German constitutional usage, certain states are composed essentially of one city that holds the full powers of a state, creating a close link between municipal and state governance. In practice, Stadtstaaten have responsibilities and competences equivalent to other Länder (states) about internal administration, education, police, and infrastructure, while retaining a strong urban identity.

Examples in Germany: The three German city-states are Berlin, Hamburg, and Bremen. Berlin is both the capital and a Land with city-wide administration; Hamburg and Bremen are states that are organized around major urban centers. These Stadtstaaten participate in the federal system with representation in national and regional institutions, and their constitutions reflect their status as cities with state authority.

Other city-states: Outside Germany, city-states are sovereign polities whose territory is centered on a single city. Well-known examples include Singapore, Monaco, and Vatican City. Such states have full international sovereignty and operate with a centralized urban administration.

Historical context: Historically, numerous city-states flourished in antiquity and the medieval and early modern periods (for example, Athens, Carthage, Venice, Genoa). They often achieved wealth and influence through trade and maritime power and gradually integrated into larger political entities.
