There are '''no''' contemporary written records of Chakavian-Slavic speakers (Croatian tribes) invasion/migration/settlement or about the events as a whole within the area itself. It is quite possible that the area had a drop in population (due to Frankish-Avar wars) and the military presents of the Byzantine Empire (Eastern Roman Empire) and the Carolingian Empire was minimal ''or'' even non existent. This would have lead to an easy invasion the of the area (opportunity beckons). The Roman Latin-Illyrian population as well as Liburnians, Greeks and others would have to have endured the arrival of the Sclaveni (Slavs). The Roman population survived within the coastal cities,on the islands and in the inhospitable Dinaric Alps. | There are '''no''' contemporary written records of Chakavian-Slavic speakers (Croatian tribes) invasion/migration/settlement or about the events as a whole within the area itself.
