We have few facts concerning Daniel; they are not to be found in Russian chronicles. He was among the best of the princes—a man who worked in the gloomy days of Mongol oppression. Daniel’s work was continued by his son Ivan, surnamed Kalitá (Purse). As his father had gathered around Moscow a whole principality and his residence had become the capital of a coming empire, so Ivan began to gather round Moscow all the unconnected parts of the country, and in his day the city appeared as the center of Great Russia, its genuine capital, and Vladimir ceased to be important. Though without the splendid virtues of his father, he, more than any of his brothers, resembled him. A churchgoer, he loved home and economy,—the latter he carried to excess even. His predecessors had struggled for the Grand Principality, but Ivan left this work to Yuri, his brother, and improved that which his father had left him. To things beyond Moscow, Ivan paid no attention. During twenty-five years his name was mentioned rarely. Meanwhile he was toiling at the heritage left by Nevski and winning strength in it. One of his great works consisted of clearing the whole principality of thieves, evil-doers and robbers. There was no such order anywhere in that day as in Moscow, and the city increased through immigration and otherwise beyond all places. Besides other advantages, the central position of this principality helped it immensely. In it the roads crossed in every direction. The great water system began in its borders. Craftsmen, traders and people of all kinds came readily to settle in Moscow. Land-tillers found it more to their profit to live there than in places torn by quarrels. Hence Moscow was made up of men from every part of Russia. Next to Moscow was Tver, but there was less strength in Tver and less order. The turmoils of Novgorod were felt in Tver somewhat, and Tver was more exposed to raids from Lithuania. The place was, moreover, distinguished for an almost frivolous and insolent demeanor toward Mongols; hence in Moscow there was less danger from Mongols. All these causes taken together made Tver less desirable to immigrants than Moscow.
