How did the tatar (mongol) conquest of russia shape russian history?

The crushing victories of Batu's armies initiated nearly two and one-half centuries of Mongol dominance in Russia. Russian princes were forced to submit as vassals of the khan of the Golden Horde and to pay tribute or risk the ravages of Mongol raiders. Mongol exactions fell particularly heavily on the Russian peasantry, who had to yield up their crops and labor to both their own princes and the Mongol overlords. Impoverished and ever fearful of the lightning raids of Mongol marauders, the peasants fled to remote areas or became, in effect, the serfs of the Russian ruling class in return for protection.

The decision on the part of many peasants to become the lifetime laborers of the nobility resulted in a major change in the rural social structure of Russia. Until the mid-19th century, the great majority of the population of Russia would be tied to the lands they worked and bound to the tiny minority of nobles who owned these great estates. Some Russian towns made profits on the increased trade Mongol links made possible, and sometimes the gains exceeded the tribute they paid to the Golden Horde. No town benefited from the Mongol presence more than Moscow. Badly plundered and partially burned in the early Mongol assaults, the city was gradually rebuilt and its ruling princes steadily swallowed up nearby towns and surrounding villages. After 1328, Moscow also profited from its status as the tribute collector for the Mongol khans. Its princes not only used their position to fill their own coffers, they annexed further towns as punishment for falling behind on the payment of their tribute.

As Moscow grew in strength, the power of the Golden Horde declined. Mongol religious toleration benefited both the Orthodox church and Moscow. The Metropolitan, or head of the Orthodox church, was made the representative of all the clergy in Russia, which did much to enhance the church's standing. The choice of Moscow as the seat of the Orthodox leaders brought new sources of wealth to its princes and buttressed Muscovite claims to be Russia's leading city. In 1380, those claims received an additional boost when the princes of Moscow shifted from being tribute collectors to being the defenders of Russia. In alliance with other Russian vassals, they raised an army that defeated the forces of the Golden Horde at the battle of Kulikovo.
