Exasperated by Dmitry's influence, Prince Ivan Kalita of the Grand Duchy of Moscow engineered his murder by the Mongols in 1326. On hearing the news of this crime, the city revolted against the Mongol Horde. The Horde joined its forces with Muscovites and brutally repressed the rebellion. Many citizens were killed, enslaved or deported. This was the fatal blow to Tver's aspirations for supremacy in Russia.
