What was a result of the crusades?

a. european conquest of the middle east
b. fall of the byzantine empire
c. growth of trade with the middle east
d. rise of charlemagne's empire

C. Growth of trade with the Middle East.

Because the Crusaders have ruled the Middle East for awhile, they established connections with some of the people groups there. And even though they lost the war, they still brought back valuable inventions and products (not inventions, like food, etc) that helped europeans in many way

hope this helps
