Iuri Dolgoruki gave form and name to this dominion of the frontier forests, but he spent most of his time and energy upon the conquest of Kief. To his son, Andrei Bogoliubski, was left the care of developing the incipient state, and of indicating in his own character and temper the type of the future rulers of the Russias. Andrei, ill at ease in the cities of the Dnieper, where the freedom of the citizens sometimes conflicted with the will of the princes, withdrew from his palace at Virishegorod and established himself upon the Kliasma, at Vladimir, which he enlarged by a suburb, named from its princely builder, Bogoliuboro. A successful campaign against the Russian Bulgarians, a compulsory alliance of several of the minor princes under his standards, and his destruction of Kief, caused him rightfully to be regarded as the strongest, the foremost of all the princes. After the violation of the mother of Russian cities, he turned his arms against Novgorod the Great, capital of the glorious principality of that name, the state that had chosen and called Rurik, the mighty republic of the north. But the subjugation of this powerful city was another affair from that of Kief. “The Kievans, accustomed to a change of masters, fought only for the honor of their princes,” writes Karamsin, “while the Novgorodians were to shed their blood in defense of the laws, the institutions, the liberties founded for them by their ancestors.” When Mstislaf Andreivitch, captain of the army that had pillaged “the holy city” of Kief, appeared at the gates of the free city of Novgorod, the inhabitants took oath to die for Saint Sophia, the citadel of their faith and their freedom. Their Archbishop, Ivan, bearing aloft an image of the Mother of God, moved at the head of a solemn procession around the ramparts. Tradition tells us that the beloved Ikon, struck by a Suzdalian arrow, turned her face toward her city, and moistened the episcopal vestments with her tears. An ecstasy of rage seized the freemen. A panic smote the besiegers. “Novgorod! Saint Sophia!” a sharp cry rushed as in a whirlwind around the ramparts. The Suzdalians fell as falls the flock of small birds beneath the swoop of the eagle. After the victory, the markets of Novgorod were so crowded with Suzdalian slaves that any number could be bought for a marten’s skin. Yet in time, even the Novgorodians made terms with their powerful subtle neighbor. Suzdal controlled the Volga, by whose waters came the corn supplies for the great, free city. Its citizens, “of their own free will,” according to the invariable phrasing of their documents, agreed to accept for their prince one of Andrei’s choosing.
