Pentapolis

A pentapolis, from the Greek words πέντε (pente), "five" and πόλις (polis), "city(-state)" is a geographic and/or institutional grouping of five cities. This was probably done in the ancient world for political, commercial and military reasons like happen later with the UK's Cinque Ports.
