The Avar Khaganate collapsed around 803 as a result of several successful military campaigns launched by the Franks against it. The fall of the Khaganate contributed to the rise of new polities among the Slavs in the region. The shift in political control was accompanied by changes in military strategy and equipment. According to Curta, swords and other items of the "Blatnica-Mikulčice horizon" show "a shift from the mounted combat tactics typical of nomadic warfare to heavy cavalry equipment", and the development of a local elite in the regions to the north of the river Danube and the Great Hungarian Plain in the early 9th century.
