The hegemony of the prince of Kiev depended on the cohesion of the clan of Rurik and the relative importance of the southern trade, both of which began to decline in the late 11th century. This decline seems to have been part of a general shift of trade routes that can for convenience be associated with the First Crusade (1096–99) and that made the route from the Black Sea to the Baltic less attractive to commerce. At the same time, conflicts among the Rurikid princes acquired a more pronounced regional and separatist nature, reflecting new patterns in export trade along the northern and western periphery. Novgorod, in particular, began to gravitate toward closer relations with the cities of the Hanseatic League, which controlled the Baltic trade. Smolensk, Polotsk, and Pskov became increasingly involved in trade along western land routes, while Galicia and Volhynia established closer links with Poland and Hungary. The princes of these areas still contested the crown of the “grand prince of Kiev and all of Rus,” but the title became an empty one; when Andrew Bogolyubsky (Andrew I) of Suzdal won Kiev and the title in 1169, he sacked the city and returned to the upper Volga, apparently seeing no advantage in establishing himself in the erstwhile capital. (Roman Mstislavich of Galicia and Volhynia repeated these actions in 1203.) By the middle of the 12th century, the major principalities, owing to the prosperity and colonization of the Kievan period, had developed into independent political and economic units.

Social and political institutions

The paucity of evidence about social and political institutions in Kievan Rus suggests that they were rudimentary. The East Slavs had no significant tradition of supratribal political organization before the coming of the Varangians, who themselves, until well into the 10th century, had little interest in institutions more elaborate than those necessary for the exploitation of their rich, new territory. The territory of Rus, moreover, was immense and sparsely settled. The scattered towns, some probably little more than trading posts, were separated by large primeval forests and swamps.

Thus, although the campaigns of Svyatoslav indicate the extent of the political vacuum that his clan filled, he construed his domains as a clan possession rather than as a territorial or national state. His successor, Vladimir, however, seems to have been conscious of one political element—organized religion—that distinguished both the contemporary empires and the newly established principalities in Poland and Hungary from his own. The church provided the concepts of territorial and hierarchical organization that helped to make states out of tribal territories; its teachings transformed a charismatic prince into a king possessing the attributes and responsibilities of a national leader, judge, and first Christian of the realm.

Once Vladimir had adopted Christianity in 988, his rule was supported by the propagation of Byzantine notions of imperial authority. The political traditions and conditions of Rus, however, required that the actual workings of the political system and some of its style be derived from other sources. The succession system, probably a vestige of the experience of the Rus khaganate in the upper Volga, was based upon two principles: the indivisibility of the basic territory of Rus (the principalities of Kiev, Chernigov, and Pereyaslavl) and the shared sovereignty of a whole generation. Seniority passed through an ascension by stages from elder brother to younger and from the youngest eligible uncle to the eldest eligible nephew. Such a system was admirably suited to the needs of the dynasty, because, by providing a rotating advancement of members of the clan through apprenticeships in the various territories of the realm, it assured control of the key points of the far-flung trading network by princes who were subject to traditional sanctions, and it gave them experience in lands over which they could someday expect to rule from Kiev. This system served well for a century after it was given final form by Vladimir and was revived by Monomakh (Vladimir II, ruled 1113–25), but it could not survive the decline of Kiev’s importance.

Individual Rurikid princes maintained military retinues led by boyars. The princes and boyars drew their most significant revenues from the tribute or taxes collected annually in kind from territories under their control and disposed of in the export trade. The bulk of the population, apparently free peasants living in traditional agricultural communes, had little other connection with the dynasty and its trading cities.

Little is known of law in this period; it may be assumed that juridical institutions had not developed on a broad scale. The earliest law code (1016), called the “Russian Law,” was one of the “Barbarian” law codes common throughout Germanic Europe. It dealt primarily with princely law—that is, with the fines to be imposed by the prince or his representative in the case of specified offenses.

Some scholars have held that, since land was in the hands of the boyar class, who exploited the labour of slaves and peasants, Kievan society should be termed feudal. The meagre sources indicate, however, that Kiev experienced nothing like the complex and highly regulated legal and economic relationships associated with feudalism in western Europe. Kiev’s political system existed primarily for and by international trade in forest products and depended on a money economy in which the bulk of the population scarcely participated. The subsistence agriculture of the forest regions was not the source of Kiev’s wealth, nor was it the matrix within which law and politics and history were made.

Formal culture came to Rus, along with Christianity, from the multinational Byzantine synthesis, primarily through South Slavic intermediaries. A native culture, expressed in a now-lost pagan ritual folklore and traditions in the arts and crafts, existed before the Kievan period and then persisted alongside the formal culture, but its influence on the latter is conjectural.

No single one of the regional (or, later, national) cultures, perhaps least of all that of Muscovy, can be called the heir of Kiev, although all shared the inheritance. The strands of continuity were everywhere strained, if not broken, in the period after Kiev’s decline. But “Golden Kiev” was always present, in lore and bookish tradition, as a source of emulation and renascence.
