White Croatia
White Croatia (also Great Croatia or Chrobatia; Croatian: Bijela Hrvatska, also Velika Hrvatska) is a historical region from which a portion of the White Croats emigrated to the area of modern-day Croatia and in which they lived between the 7th and 10th centuries.
According to recent archaeological and historiographical research it is considered it existed as a tribal proto-state with polis-like gords of Plisnesk, Stilsko, Revno, Halych, Terebovlia among others in Western Ukraine, which lasted until the very end of the 10th century. Some historians believe that, after the migration of the Croats in the 6th-7th century, their former homeland gradually lost its primacy, being influenced and assimilated by other Slavic peoples, such as Ukrainians (Kievan Rus'), Poles (Duchy of Poland) and Czechs (Great Moravia, Duchy of Bohemia). Others say there was never a distinct polity known as Great or White Croatia.
According to the medieval Chronicle of the Priest of Duklja, another area referred to as White Croatia was located south of Posavina along with Red Croatia in Dalmatia.
