Prostor od Alpa i Jadrana do Dunava i Neretve u svjetlu materijalnih tragova inzularne umjetnosti karolinškog doba

Alps to the danube and the neretva, or to the eastern Adriatic. This provided support to the vassal slavic gentile principalities and the remaining Avar population in the vast interspace from the danube in the north to the eastern Adriatic coast in the south for integration into the Frankish empire. This entire process of missionary activity, baptising of the population, and church and administrative organization, took place in the period from the destruction of the Avar khaganate in 796, and finally in 803, until the conclusion of the peace in Aachen in 812. it should be remembered that the byzantine empire, the second strongest european power of the time, with which the Treaty of Aachen was signed in 812 during the reign of michael i rhangabe, managed – owing to its thalassocracy and ambitions – to stipulate a string of urban agglomerati-ons along the Adriatic archipelago and its immediate hinterland. These towns have been a continuous factor of the creation of unique cultural dynamics in the territory covered by the title of this paper.
