The prince suffered more and more from those visits to the Horde. In former days he seemed stern and serious after each of them, but now he seemed worn and exhausted. His health did not promise long life to him. The demands of the Mongols were increasing, and soon a decision was published which brought all men to despair when they heard it. No one had power to set aside or change this decision. The Khan commanded to take a great census, to count all his subjects, and increase his income by imposing a head tax. This time Nevski’s intercession was useless. The greedy master of the Horde insisted on his decision, adding that such was the will of the Grand Khan. Mangu had in fact commanded to enumerate all men and things under Mongol dominion. Officials of the Horde appeared first in Ryazan and in Murom. There they counted the people and described the land minutely. Dues were imposed upon all men except the clergy. Town and village property, and occupations were described in this census. The officials went thence to Suzdal, Rostoff, and Vladimir. One year and a second had passed before they finished. They did this work with great care, without haste, and most accurately. Next inspectors appeared to ensure the close gathering of the tribute and taxes. All this time an ominous sound was heard coming from Novgorod, though there had been order in the city since the second installation of Nevski’s son, Vassili, now sixteen years of age and well conversant with the affairs of that place. Nevski was observing the census carefully everywhere, in places ruled by others as well as by himself. His labor in studying this work took much of his time and strength. In the winter of 1257–1258 the Mongols were sent to Novgorod to enumerate the inhabitants and property of that place. When the officials were leaving Vladimir, Nevski gave them as assistants a number of his own men, but he did not go himself, since he wished to hear from his son before further action. While he was waiting for news, the chief Mongols came rushing back to Vladimir in anger. How they had been offended in Novgorod no man could learn from their account and their outcries. With a great din they attacked the prince, saying that they had gone to Novgorod believing in his word, but if they were to be treated in this way they would throw aside everything and go back to the Golden Horde straightway. Nevski, seeing clearly the danger, summoned his brothers, Boris from Rostoff, and Andrei from Suzdal, but only with great difficulty could he detain the Mongols. At last, however, they consented to return to Novgorod, if accompanied by Nevski and his brothers. The Grand Prince, upon approaching Novgorod, was surprised that his son did not come out to meet him. Most of the Mongols had followed their superiors to Vladimir, only a few had remained in the city; these declared that no census had been made, and added: “We know not what is happening.”
