Ivan Moneybags who collected tribute for the Golden Horde.
Compare Ivan I Kalita with another historical figure:
Ivan I became Grand Prince of Moscow after his brother Yuri's death. He secured the title by cooperating with the Mongol Golden Horde, using his position to collect tribute from other Russian principalities on behalf of the Khan.
Ivan I persuaded Metropolitan Peter to move his residence from Vladimir to Moscow. This made Moscow the ecclesiastical center of the Russian Orthodox Church, greatly enhancing its political and religious authority.
When Tver rebelled against Mongol tax collectors, Ivan I led a Mongol-Muscovite army to crush the uprising. The destruction of Tver eliminated Moscow's main rival for supremacy in northeastern Russia.
Ivan I obtained the yarlyk (patent) for the Grand Principality of Vladimir from the Mongol Khan Uzbek. This made Moscow the primary collector of tribute for the Horde and the most powerful Russian principality.
