Several princes who proved insubordinate were summoned to the camp of the Horde and there tried and executed. Rivals sought the khan, to buy power by presents. During their journeys, which occupied a year or more, the Tartar bashaks ruled their dominions. Tartar armies aided the princes in their civil wars, and helped these ambitious lords to keep their country in a state of subjection. Fortunately for Russia, the great empire of the Mongols gradually fell to pieces of its own weight. The Kaptchak, or Golden Horde, broke loose from the Great Horde, and Russia had a smaller power to deal with. The Golden Horde itself broke into two parts. And among the many princes of Russia a grand prince was still acknowledged, with right by title to dominion over the entire realm. One of these grand princes, Alexander by name, son of the grand prince of Vladimir, proved a great warrior and statesman and gained the power as well as the title. Prince of Novgorod by inheritance, he defeated all his enemies, drove the Germans from Russia, and recovered the Neva from the Swedes, which feat of arms gained him the title of Alexander Nevsky. The Tartars were too powerful to be attacked, so he managed to gain their good will. The khan became his friend, and when trouble arose with Kief and Vladimir their princes were dethroned and these principalities given to the shrewd grand prince. Russia seemed to be rehabilitated. Alexander was lord of its three capitals, Novgorod, Kief, and Vladimir, and grand prince of the realm. But the Russians were not content to submit either to his authority or to the yoke of the Tartars. His whole life was spent in battle with them, or in journeys to the tent of the khan to beg forgiveness for their insults. The climax came when the Tartar collectors of tribute were massacred in some cities and ignominiously driven out of others. When these acts became known at the Horde the angry khan sent orders for the grand prince and all other Russian princes to appear before him and to bring all their troops. He said that he was about to make a campaign, and needed the aid of the Russians. This story Alexander did not believe. He plainly perceived that the wily Tartar wished to deprive Russia of all its armed men, that he might the more easily reduce it again to subjection. Rather than see his country ruined, the patriotic prince determined to disobey, and to offer himself as a victim by seeking alone the camp of Usbek, the great khan, a mission of infinite danger. He hoped that his submission might save Russia from ruin, though he knew that death lay on his path. He found Usbek bitterly bent on war, and for a whole year was kept in the camp of the Horde, seeking to appease the wrath of the barbarian. In the end he succeeded, the khan promising to forgive the Russians and desist from the intended war, and in the year 1262 Alexander started for home again.
