Rus' Khaganate
Boguslavsky and Machinskaya date the earliest Scandinavian burial at Alaborg to ca. 700 CE. Archaeologically, the site has much in common with Ladoga. It seems that the two sites developed on parallel lines. Alaborg was destroyed by fire and abandoned before the 930s, most likely towards the end of the 9th century. At that period all the other centres of the Rus' Khaganate faced with destruction, which Constantine Zuckerman associates with Vadim's uprising, as recorded in the East Slavic chronicles.
