Donatus Magnus was a fourth-century bishop in North Africa who established the Donatist movement. Born around 250, he rose to prominence following the Diocletianic Persecution, a period when many clergy surrendered sacred texts to Roman authorities. Donatus led a faction that believed such individuals, known as traditores, had forfeited their spiritual legitimacy. This theological disagreement led to a significant schism within the North African church, as Donatus contested the validity of ordinations performed by those who had compromised during the persecutions.
