In what way did Mongol invasions affect Persia and Russia similarly?

A. The Mongols established a centralized religion

B. The Mongols established a central code of laws and policies

C. The Mongols created a farming incentive program

D. The Mongols created a central mail system

The answer is letter D.

The Mongols created a central mail system where information dissemination through its kingdoms were fast enough and could reach its farthest empires. Persia and Russia are among the countries that the Mongol Empires have conquered because of this system. These were postal stations that also transported foreign and domestic tribute. Trade was also one of the major impacts of this system both to Russia and Persia.

The main effect that the Mongol invasion had on Persia and Russia in terms of similarity was the creation of a central mail system - D. The Mongols knew that by having such a system it would be much easier to control the vast swathes which the Mongol empire was covering. For that reason, they were able to transmit messages much faster in comparison to other empires.
