the Khaganate to be around the year 830. According to Magocsi, "A violent civil war took place during the 820s. ... The losers of the internal political struggle, known as Kabars, fled northward to the Varangian Rus' in the upper Volga region, near Rostov, and southward to the Magyars, who formerly had been loyal vassals of the Khazars. The presence of Kabar political refugees from Khazaria among the Varangian traders in Rostov helped to raise the latter's prestige, with the consequence that by the 830s a new power center known as the Rus' Kaganate had come into existence." Whatever the accuracy of such estimates may be, there are no primary sources mentioning the Rus' or its khagans prior to the 830s. Omeljan Pritsak noted that the leader of those Kabars was Khan-Tuvan. Golden (1982) and Zuckerman (2000) concluded that if a Rus' khaganate had existed, it must have disappeared before 900, as references to a Rus' khagan are last recorded in the 880s, and do not return until the 11th century. Various possible reasons for its disappearance have been suggested. The Primary Chronicle describes the uprising of the pagan Slavs and Chudes (Baltic Finns) against the Varangians, who had to withdraw overseas in 862. The First Novgorod Chronicle, whose account of the events Shakhmatov considered more trustworthy, does not pinpoint the pre-Rurikid uprising to any specific date. The 16th-century Nikon Chronicle attributes the banishment of the Varangians from the country to Vadim the Bold. The Ukrainian historian Mykhailo Braychevskiy labelled Vadim's rebellion "a pagan reaction" against the Christianization of the Rus'. A period of unrest and anarchy followed, dated by Zuckerman to 875–900. The absence of coin hoards from the 880s and 890s suggests that the Volga trade route ceased functioning, precipitating "the first silver crisis in Europe". After this economic depression and period of political upheaval, the region experienced a resurgence beginning in around 900. Zuckerman associates this recovery with the arrival of Rurik and his men, who turned their attention from the Volga to the Dnieper, for reasons as yet uncertain. The Scandinavian settlements in Ladoga and Novgorod revived and started to grow rapidly. During the first decade of the 10th century, a large trade outpost was formed on the Dnieper in Gnezdovo, near modern Smolensk. Another Dnieper settlement, Kiev, developed into an important urban centre roughly in the same period. Possible locations The location of the purported
