The Tver Uprising of 1327 (Russian: Тверское восстание) was the first major uprising against the Golden Horde by the people of Vladimir. It was brutally suppressed by the joint efforts of the Golden Horde, Muscovy and Suzdal. At the time, Muscovy and Vladimir were involved in a rivalry for dominance, and Vladimir's total defeat effectively ended the quarter-century struggle for power. The Golden Horde later became an enemy of Muscovy, and Russia did not become free of Mongol influence until the Great stand on the Ugra river in 1480, more than a century later. Background In the early 13th century, the Mongol Empire invaded the Kieven Rus' and proceeded to establish a hegemony over the Rus' states. Among the most important of these was the duchy of Vladimir, the most powerful Rus' principality at the time. The extent of Mongol power was so great that the Golden Horde had the power to issue a jarlig, or decree, that allowed the Rus' princes to rule over their lands, only if they swore allegiance to the Mongol Empire. When confidence fell for the rule of the princes of Vladimir, various factions in the principality began to jostle for power, and the region divided itself into several states, including Tver, Moscow, and others. All these states acknowledged the rule of the prince of Vladimir, but the power had become notional at best by the dawn of the fourteenth century. In autumn of 1326, Alexander, the prince of Tver, received a jarlig from the Mongol Öz Beg Khan, authorizing the prince to rule Vladimir. About a year later, Öz Beg's cousin, Chol-khan, arrived in Tver with a large retinue and removed Alexander from the prince's palace in an apparent reversal of the grant. Instead, Chol-khan took residence in Alexander's former home and began a campaign of persecution against the Christians of Tver in which numerous atrocities were committed, including rape, robbery and beatings. A rumor arose among the people of a Mongol plan to kill all the princes of the principality of Vladimir on the day of the feast of the Dormition of the Mother of God, make Chol-khan the new ruler of Tver and force the people to convert to Islam, although the verity of the rumor is disputed. The people of Tver turned to Alexander to address the issue, but he urged them to "endure." Events Despite Alexander's advice, a rebellion broke
