List of City-States

Coastal hubs and compact inland towns have often acted as independent political centers, shaping trade routes, law and culture beyond their geographic size. Their networks of commerce, diplomacy and defense make these places key pieces in regional histories and modern curiosities alike.

There are 30 City-States, ranging from Amalfi to Venice. Each entry lists Country, Status, Era (years) so you can see where and when these polities held sway — you’ll find below.

How were the places chosen for this list?

Entries are selected for historical or legal independence: cities that functioned as self-governing polities, held recognized diplomatic relations, or issued charters/coinage distinguishing them from regular towns. Sources include historical records and scholarly references; the Status and Era columns indicate differing degrees and periods of autonomy.

How should I read the Country, Status, Era (years) columns when comparing items?

Use Country to group geographic context, Status to note whether a city was fully sovereign, a protectorate, or a vassal, and Era (years) to track temporal overlap. Keep in mind definitions of sovereignty changed over time, so cross-check entries if you need precise legal or chronological comparisons.
