The Tartar yoke lasted from 1237 to 1462—more than two centuries; a yoke not only crushing, but dishonouring and withering the very soul of the people that fell its prey. The Mongol Tartars established a rule of systematic terror, devastation and wholesale massacre forming its institutions. Their numbers being scanty in proportion to their enormous conquests, they wanted to magnify them by a halo of consternation, and to thin, by wholesale slaughter, the populations which might rise in their rear. In their creations of desert they were, besides, led by the same economical principle which has depopulated the Highlands of Scotland and the Campagna di Roma—the conversion of men into sheep, and of fertile lands and populous abodes into pasturage.
The Tartar yoke had already lasted a hundred years before Muscovy emerged from its obscurity. To entertain discord among the Russian princes, and secure their servile submission, the Mongols had restored the dignity of the Grand Princedom. The strife among the Russian princes for this dignity was, as a modern author has it, "an abject strife—the strife of slaves, whose chief weapon was calumny, and who were always ready to denounce each other to their cruel rulers; wrangling for a degraded throne, whence they could not move but with plundering, parricidal hands—hands filled with gold and stained with gore; which they dared not ascend without grovelling, nor retain but on their knees, prostrate and trembling beneath the scimitar of a Tartar, always ready to roll under his feet those servile crowns, and the heads by which they were worn." It was in this infamous strife that the Moscow branch won at last the race. In 1328 the crown of the Grand Princedom, wrested from the branch of Tver by dint of denunciation and assassination, was picked up at the feet of Usbeck Khan by Yury, the elder brother of Ivan Kalita. Ivan I. Kalita, and Ivan III., surnamed the Great, personate Muscovy rising by means of the Tartar yoke, and Muscovy getting an independent power by the disappearance of the Tartar rule. The whole policy of Muscovy, from its first entrance into the historical arena, is resumed in the history of these two individuals.
