Peter of Alexandria was the 17th Patriarch of Alexandria, serving from approximately 300 to 311. Born and raised in Alexandria, he rose through the ecclesiastical ranks from reader to deacon and priest before being selected as bishop. His leadership coincided with the intense Diocletianic Persecution, during which he provided spiritual guidance to his followers through letters and clandestine visits to the imprisoned. He is remembered as a hieromartyr for his death during this period of Roman persecution.
