How did rivalries split Islam?

Rivalries in early Islam, particularly between the supporters of Ali and those of Abu Bakr, led to profound divisions within the Muslim community. The disagreement over rightful leadership after the Prophet Muhammad's death resulted in the Sunni-Shia split, which has persisted through centuries. Political power struggles, differing interpretations of Islamic teachings, and cultural contexts further exacerbated these divisions, leading to distinct religious identities and practices. This schism has had lasting implications for Islamic history and sectarian relations.
