Eusebius of Caesarea, (260?–340?), a Christian scholar and writer, called “the Father of Church History.” He became bishop of Caesarea in Palestine about 315 and was a leader in the First Council of Nicaea (325). Eusebius's Ecclesiastical History is the chief source of information about Christianity from the age of the apostles to the writer's own time.
