Describe the role of the turks in the spread of the hegemony of islamic political systems
LenKa [72]

Answer:

Another effect of the spread of Islam was an increase in trade. Unlike early Christianity, Muslims were not reluctant to engage in trade and profit; Muhammad himself was a merchant. As new areas were drawn into the orbit of Islamic civilization, the new religion provided merchants with a safe context for trade.
