معاوية بن أبي سفيان
Agathon served like this until Pope Benjamin returned and died, at which time Agathon was officially named the pope of the Coptic Orthodox Church. This happened during the time of the Muslim conquest of Egypt and when Muawiyah I was ruling. Unlike most popes who first serve as monks, Agathon had never been a monk prior to becoming pope- yet he was successful.
