Georges, now confirmed in the dignity of grand prince by the khan, returned to Vladimir, where he established his government, sending his brother to Novgorod to reign over that principality in his name.  Dmitri, and others of the sons of Michel, for several years waged implacable warfare against Georges, with but little success.  The khan, however, did not deign to interfere in a strife which caused him no trouble.  But in the year 1325 Georges again went to the horde on the eastern banks of the Caspian.  At the same time, Dmitri appeared in the encampment.  Meeting Georges accidentally, whom he justly regarded as the murderer of his father, he drew his sword, and plunged it to the hilt in the heart of the grand prince.  The khan, accustomed to such deeds of violence, was not disposed to punish the son who had thus avenged the death of his father.  But the friends of Georges so importunately urged that to pardon such a crime would be an ineffaceable stain upon his honor, would be an indication of weakness, and would encourage the Russian princes in the commission of other outrages, that after the lapse of ten months, during which time Dmitri had been detained a captive, Usbeck ordered his execution, and the unfortunate prince was beheaded.  Dmitri was then but twenty-seven years of age.

And yet Usbeck seems to have had some regard for the cause of the young prince, for he immediately appointed Alexander, a brother of Dmitri, and son of Michel, to succeed Georges in the grand principality.  The Novgorodians promptly received him as their ruler.  Affairs wore in this State when, at the close of the summer of 1327, an embassador of Usbeck appeared, with a band of Tartars, and entered the royal city of Tver, which was the residence of Alexander.  The principality of the Tver was spread along the head waters of the Volga, just north of the principality of Moscow.  The report spread through the city that the Mogol embassador, Schevkal, who was a zealous Mohammedan, had come to convert the Russians to Mohammedanism, that he intended the death of Alexander, to ascend the throne himself, and to distribute the cities of the principality to his followers.

The Tverians, in a paroxysm of terror and despair, rallied for the support of their prince and their religion.  In a terrible tumult all the inhabitants rose and precipated themselves upon the embassador and his valiant body guard.  From morning until night the battle raged in the streets of Tver.  The Tartars, overpowered by numbers, and greatly weakened by losses during the day, took refuge in a palace.  The citizens set the palace on fire, and every Tartar perished, either consumed by the flames or cut down by the Russians.
