The Sunni-Shia split, a fundamental division in Islam, stems from disagreements over leadership after Muhammad's death in 632 CE. This schism shaped Islamic political and theological landscapes, influencing religious practices, governance, and cultural identities across the Muslim world.

The split centers on whether leadership should pass to Muhammad's closest male relative or the most qualified individual. This dispute led to distinct theological frameworks, with Sunnis emphasizing elected leadership and Shias advocating hereditary succession through Muhammad's bloodline, specifically Ali.

Origins of the split
