Chrobatian/Freeciv

Description
Chrobatia was an Early Medieval, semi-legendary Slavic state organised by the White Croats in a part of Central Europe that can not be conclusively identified today. The main source of the existence of a White Croatian state is a mention by the Byzantine Emperor Constantine VII Porphyrogennetos. White Croatia is sometimes associated with a prince Slavnik, lord of Libice, whose influence extended to the region of Silesia and the land of Krakow.
