Explore the ancient Greek world through an interactive map of 1,035 poleis (city-states) from the Archaic and Classical periods (c. 650–325 BCE). Polis Inventory brings together geographic and historical information about ancient Greek settlements, allowing you to explore their locations, examine their characteristics, and discover patterns across the Greek world. Explore and Discover - View 1,035 ancient Greek poleis on an interactive map, with terrain and geographic context. - Search for individual poleis by name or explore them geographically. - Filter settlements using 20 geographic and historical parameters. - Examine detailed information about each polis, including its history, political organization, territory, and coinage. - Export the complete dataset in GeoJSON format for use in other mapping and research applications. Built on Scholarly Research Polis Inventory is based on *An Inventory of Archaic and Classical Poleis* by M. H. Hansen and T. H. Nielsen (Oxford University Press, 2004), a pioneering publication of the Copenhagen Polis Centre, referred to here as the “HN Inventory.” The digital dataset comes primarily from polis.stanford.edu, maintained by Stanford University's Department of Classics. It reflects ongoing digitization and enhancement of the original work by the Stanford team and subsequent scholars. We continue to refine the dataset by improving geographic locations, correcting errors, and incorporating additional historical information. Definitions of the historical and geographic parameters are available within the app. Further details, documentation, and attribution can be found at odysseymaps.io, polis.stanford.edu, and in the HN Inventory itself. Free and Independent Polis Inventory is free to use. An optional Tip Jar supports ongoing development; tips are voluntary and do not unlock features. Privacy: No user data is tracked or stored by Polis Inventory. Independence: Polis Inventory is an independent companion to the HN Inventory and is not affiliated with, sponsored, or endorsed by Stanford University or Oxford University Press.
