At the turn of the XIII-XIV centuries. the great princedoms of the North-East of Russia have broken up into allotments-smaller independent principalities. In the XIV century. strengthened the Moscow and Tver principality. They began among themselves a fierce struggle for the Grand Duchy of Vladimir. The Moscow principality won, which extended its power to several neighbors. Moscow Prince Yuri Danilovich married the sister of the Horde Khan and received from him a shortcut to the Vladimir throne. His rival, Tver prince Michael, he slandered in the Horde and lived with the light. But Yuri Danilovich was not happy for his luck for long, since he died at the hands of a young avenger – the son of Mikhail Tversky, who was executed by the Horde.
After the death of the Moscow prince Yuri Orda returned a label to the Grand Duchy of Vladimir Prince of Tver. The happy owner of the label returned to Tver, accompanied by the Tatars, who at once took up their trade-the plundering of the city. Desperate residents of Tver revolted, hoping to put an end to the Tatar nightmare. This took advantage of the Moscow prince Ivan, nicknamed for thrift and a commercial vein Kalita – “a bag of money.” With the help of the Tatars he pacified the insurgents, deserving a Khan’s label for the principality in Vladimir.
Ivan Kalita believed that it is better not to irritate the khan, but by feigned meekness to win his favor. None of the Russian princes did not cover the thresholds of the Khan’s capital more often than he did, so the Mongol-Tatars left the Moscow principality alone. A considerable support for Ivan Kalita was the relocation from Vladimir to Moscow of the Metropolitan of Kiev and All Russia. The power of Ivan Kalita extended to several neighboring principalities. So, not Tver, and Moscow became the political center of North-Eastern Russia.
