Explanation:

After the death of the Islamic prophet Muhammad, a disagreement over who should succeed him as the leader of the Muslim community led to a split between two major branches of Islam: Sunni and Shi'a. The Crusades were conflicts between Christian and Muslim powers, unrelated to this succession dispute. The beginnings of Christianity predate Islam entirely, and Islam did not end as a result of this disagreement.

B. the Sunni and Shi'a split
