City-state

A city-state is an independent sovereign city which serves as the center of political, economic, and cultural life over its contiguous territory. They have existed in many parts of the world since the dawn of history, including cities such as Rome, Athens, Sparta, Carthage, and the Italian city-states during the Middle Ages and Renaissance, such as Florence, Venice, Genoa and Milan.

With the rise of nation states worldwide, only a few modern sovereign city-states exist, with some disagreement as to which qualify; Monaco, Singapore and Vatican City are most commonly accepted as such. Singapore is the clearest example, with full self-governance, its own currency, a robust military and a population of 5.5 million.

Several non-sovereign cities enjoy a high degree of autonomy and are sometimes considered city-states. Hong Kong, Macau, and members of the United Arab Emirates—most notably Dubai and Abu Dhabi—are often cited as such.

Historical background

Ancient and medieval world

Historical city-states included Sumerian cities such as Uruk and Ur; Ancient Egyptian city-states, such as Thebes and Memphis; the Phoenician cities (such as Tyre and Sidon); the five Philistine city-states; the Berber city-states of the Garamantes; the city-states of ancient Greece (the poleis such as Athens, Sparta, Thebes, and Corinth); the Roman Republic (which grew from a city-state into a vast empire); the Italian city-states from the Middle Ages to the early modern period, such as Florence, Siena, Ferrara, Milan (which as they grew in power began to dominate neighboring cities) and Genoa and Venice, which became powerful thalassocracies; the Mayan and other cultures of pre-Columbian Mesoamerica (including cities such as Chichen Itza, Tikal, Copán and Monte Albán); the central Asian cities along the Silk Road; the city-states of the Swahili coast; Ragusa; states of the medieval Russian lands such as Novgorod and Pskov; and many others. Danish historian Poul Holm has classed the Viking colonial cities in medieval Ireland, most importantly the Kingdom of Dublin, as city-states.

In Cyprus, the Phoenician settlement of Kition (in present-day Larnaca) was a city-state that existed from around 800 BC until the end of the 4th century BC.

Some of the most well-known examples of city-state culture in human history are the ancient Greek city-states and the merchant city-states of Renaissance Italy, which organised themselves as independent centers. The success of regional units coexisting as autonomous actors in loose geographical and cultural unity, as in Italy and Greece, often prevented their amalgamation into larger national units. However, such small political entities often survived only for short periods because they lacked the resources to defend themselves against incursions by larger states (such as Roman conquest of Greece). Thus they inevitably gave way to larger organisations of society, including the empire and the nation-state.

Central Europe

In the Holy Roman Empire (962–1806) over 80 Free Imperial Cities came to enjoy considerable autonomy in the Middle Ages and in early modern times, buttressed legally by international law following the Peace of Westphalia of 1648. Some, like three of the earlier Hanseatic cities – Bremen, Hamburg and Lübeck – pooled their economic relations with foreign powers and were able to wield considerable diplomatic clout. Individual cities often made protective alliances with other cities or with neighbouring regions, including the Hanseatic League (1358 – 17th century), the Swabian League of Cities (1331–1389), the Décapole (1354–1679) in the Alsace, or the Old Swiss Confederacy ( 1300 – 1798). The Swiss cantons of Zürich, Bern, Lucerne, Fribourg, Solothurn, Basel, Schaffhausen, and Geneva originated as city-states.

After the dissolution of the Holy Roman Empire in 1806, some cities – then members of different confederacies – officially became sovereign city-states, such as the Free Hanseatic City of Bremen (1806–11 and again 1813–71), the Free City of Frankfurt upon Main (1815–66), the Free and Hanseatic City of Hamburg (1806–11 and again 1814–71), the Free and Hanseatic City of Lübeck (1806–11 and again 1813–71), and the Free City of Kraków (1815–1846). Under Habsburg rule the city of Fiume had the status of a ''corpus separatum'' (1779–1919), which – while falling short of an independent sovereignty – had many attributes of a city-state.

Italy

In Northern and Central Italy during the medieval and Renaissance periods, city-states - with various amounts of associated land - became the standard form of polity. Some of them, despite being de facto independent states, were formally part of the Holy Roman Empire. The era of the Italian states, in particular from the 11th century to the 15th century, was characterized by the remarkable economic development, trade, manufacture, and mercantile capitalism, together with increasing urbanization，with remarkable influence throughout much of the Mediterranean world and Europe as a whole. During this time, most of the Italian city-states were ruled by one person, such as the Signoria or by a dynasty, such as the House of Gonzaga and the House of Sforza.

Examples of Italian city-states during the Middle Ages and the Renaissance: Republic of Florence, Duchy of Milan, Duchy of Ferrara,
San Marino, Duchy of Modena and Reggio, Duchy of Urbino, Duchy of Mantua and the Republic of Lucca.

Another example of Italian city-states, were the powerful maritime republics: Republic of Venice, Republic of Genoa, Republic of Amalfi, Republic of Pisa, Republic of Ancona and Duchy of Gaeta.

Southeast Asia

In the history of Mainland Southeast Asia, aristocratic groups, Buddhist leaders, and others organized settlements into autonomous or semi-autonomous city-states. These were referred to as '' mueang'', and were usually related in a tributary relationship now described as mandala or as ''over-lapping sovereignty'', in which smaller city-states paid tribute to larger ones that paid tribute to still larger ones—until reaching the apex in cities like Ayutthaya, Bagan, Bangkok and others that served as centers of Southeast Asian royalty. The system existed until the 19th century, when colonization by European powers occurred. Siam, a regional power at the time, needed to define their territories for negotiation with the European powers so the Siamese government established a nation-state system, incorporated their tributary cities ( Lan Xang, Cambodia and some Malay cities) into their territory and abolished the mueang and the tributary system.
