By the time the princes of Moscow had gained seniority in northern Rus, the south-western principalities were wholly detached. Like their northern neighbours, they too had recognized the suzerainty of the Golden Horde after the Mongol invasion. But by the middle of the fourteenth century, Galicia and Volhynia had been absorbed into the realms of Poland and Lithuania. During the following decades Lithuania added Kiev, Chernigov, and Smolensk to its domain as well. The lands of Rus lost their territorial integrity.
Simultaneously, the unity of the metropolitanate was also being threatened. Despite the broadening political gulf between the northern and south-western principalities, they had all continued to form a single ecclesiastical community. After Metropolitan Maxim moved from Kiev to the north-east in 1299, however, the unity of the see was repeatedly challenged. First, the prince of Galicia secured the establishment of a short-lived metropolitanate (c.1303–8); later, the rulers of Poland and Lithuania urged the creation of separate metropolitanates for the Orthodox inhabitants of the lands they had incorporated. Church patriarchs established a series of sees (c.1315–1340s), but under pressure from the metropolitans in north-eastern Rus, disbanded each of them.
Thus, a century after the Mongols destroyed Kiev, the institutions that had given cohesion both to Kievan Rus and to the post-invasion principalities were crumbling. The state had fragmented, and the unity of the Church was in jeopardy. Furthermore, the dynasty’s complex rules of seniority and succession had been supplanted by the authority of the khans, who had begun to confer the throne of Vladimir not on the dynasty’s legitimate heirs—the senior, eligible princes—but on the princes most likely to fulfil their demands: the Daniilovichi of Moscow.
The Foundations of Muscovy
Daniilovich rule was not automatically accepted by the rest of the dynasty. Although the legitimate heir, Alexander of Tver, had been soundly defeated, opponents of Daniilovich dominance surfaced repeatedly through the fourteenth century. Their pressure compelled the Muscovite princes to adopt policies aimed at retaining Mongol favour, neutralizing the dynastic opposition, and developing domestic sources of legitimacy. As a result of such efforts to stay in power, they also strengthened their own territorial, economic, and military base. The Daniilovichi thus transformed the distribution of power in the lands of northern Rus and laid the foundations for a new state—Muscovy.
The adversaries of the Daniilovichi were also Riurikids. Their domains, known as apanages (udely), had been carved out of older, larger principalities in accordance with a custom, dating from the Kievan Rus era, of subdividing the lands ruled by a dynastic branch to accommodate all its members and also to share the responsibilities for administration and defence. The practice was particularly pronounced among the Rostov clan, whose lands were carved into numerous apanages, including Iaroslavl, Beloozero, and Ustiug. The apanage princes of Rostov joined the various coalitions against the Daniilovichi and in support of the legitimate princes from the house of Tver.
Their protests, however, made virtually no impression on the Mongol khans, who maintained the Moscow princes—Ivan Daniilovich, then his sons Semen (ruled 1341–53) and Ivan II (ruled 1353–9)—in power. Only once did an anti-Daniilovich coalition achieve success: when Ivan II died and the Golden Horde itself entered a period of internal conflict, a coalition secured the confirmation of the prince of Suzdal as grand prince. Within three years, however, the Moscow line in the person of Dmitrii Ivanovich (later known as Dmitrii Donskoi) had recovered the Vladimir throne.
Although the Mongol khans paid little attention to them, the Daniilovichi themselves did respond to their dynastic opponents. One strategy they adopted to neutralize them was to form marital alliances. Ivan I arranged marriages for his daughters with the sons of two of his most vocal opponents, the princes of Beloozero and Iaroslavl; his niece became the wife of Prince Konstantin Mikhailovich of Tver, a champion of the anti-Daniilovich group. Ivan’s son Semen married the daughter of the late Alexander of Tver despite the Church’s disapproval of this, his third marriage. In 1366 Prince Dmitrii followed the pattern by marrying the daughter of his former rival, the prince of Suzdal. These marriages, all concluded with dynastic branches whose members had been reluctant to recognize the predominance of Moscow, created bonds of kinship and alliance. Although they could not transform the Daniilovichi into the senior dynastic line, they did have the effect of elevating the Daniilovichi’s informal status with their in-laws and, thereby, helped to mute, if not completely neutralize, their opposition.
Another strategy adopted by the Daniilovichi was to subordinate princes from other branches of the dynasty and simultaneously to expand their own territorial domain. The Moscow princes ruled two sets of territories: lands that belonged to their patrimony (otchina) of Moscow and lands that were attached to the grand principality of Vladimir. Even before they became grand princes of Vladimir the princes of Moscow had extended their realm to include Serpukhov, Kolomna, and Mozhaisk; through the fourteenth century they continued to acquire new territories and add them to their patrimonial domain. Ivan Kalita is credited with aggressively expanding his family’s domain and acquiring the principalities of Beloozero and Uglich (formerly Rostov apanages) and Galich. His grandson, Dmitrii Donskoi, consolidated control over Galich, absorbed the principality of Starodub, and also brought the independent principality of Rostov under his influence.
Territorial expansion provided a variety of assets and advantages. One was control over rivers, which had strategic as well as commercial value. By acquiring Serpukhov, Kolomna, and Mozhaisk, Muscovy encompassed the entire length of the Moscow river as well as the segment of the Oka between Kolomna and Serpukhov that formed the southern boundary of the principality. Dmitrii Donskoi later sponsored the construction of walled monasteries at these towns and, thereby, fortified the border. The Moscow princes also controlled a significant section of the Volga river from Kostroma (part of the grand principality of Vladimir) to Nizhnii Novgorod. The principality of Uglich, located between two of the remaining independent principalities, Iaroslavl and Tver, contained another segment of the Volga. Remote from the main body of Moscow’s holdings were Beloozero and the independent but subordinate principality of Ustiug, which commanded the main trade routes that spanned the lands of the north.
Territorial expansion also brought a larger populace under the direct rule of the Muscovite princes. Moscow’s economic and tax base was, correspondingly, broadened. Retainers of subordinated princes, furthermore, were motivated to transfer their allegiance to Moscow, whose own military force and administrative staffs were thereby enlarged and strengthened. The Muscovite princes were able to collect transit and customs fees from the traffic and commercial transactions conducted along their roads and rivers and in their towns. Their control over segments of the Volga also gave them a greater role in the transport of goods down that river to Bulgar and Sarai, hence in the Mongols’ extensive trade network.
Even though it was growing, Moscow’s territory was divided into relatively few apanages. During the reign of Dmitrii Donskoi (1362–89), only one apanage principality (Serpukhov) was carved out of Muscovy’s lands for his cousin. After Dmitrii’s death in 1389, his eldest son (Vasilii I) inherited the throne; each of Dmitrii’s other four sons then received an apanage principality. But due to their failure to produce sons of their own, most of their lands eventually reverted to the grand prince. The only one to survive was the apanage principality of Mozhaisk (later divided into two principalities, Mozhaisk and Vereia). At least until the death of Vasilii I (1425), the few apanage princes of Moscow as well as their senior advisers and military commanders (who held the rank of boyar) were loyal supporters of the grand prince. This internal territorial and political cohesion provided a central, unified core for the expanding state of Muscovy.
