Acause of the first crusade was the
a. conquest of constantinople by the ottoman turks
b. invasion of spain by the muslim arabs
c. attack by the muslims on rome
d. conquest of asia minor by the seljuk turks

I thighs that the first crusade only happened because the Catholics wanted the holy land Jerusalem. So pope I believe urban the 2nd said to go over there and go get it leading to many crusades going back and forth. Even though the Catholic church lost they won by saying how they started cultural diffusion

Are there answer choices?
