What were some effects of Mongol occupation on Russian civilization?

After the Mongol invasion, Russians began dressing like Mongols and many cultural habits of the Mongols diffused into Russian civilization. The Mongols decreased the literacy rate and made the economy go down.

The Mongols ruled for over 200 years in Kievan Russia. They allowed people to continue their customs, but they demanded obedience and tax payments. When the Mongols first conquered, they were ruthless and burned or killed anything in their path. People would have rebellions against the Mongols.
