""These disputes over religious and political leadership would give rise to schism in the Muslim community. The majority accepted the legitimacy of the three rulers prior to Ali, and  known as Sunnis. A minority disagreed, and believed that Ali was the only rightful successor; they became known as the Shi'a.[80]""

this needs to be rewritten.. Sunnis are the Sunna followers and they are known by that name long time before accepting Ali as caliph.. hoping you got my point"
