In the Council of Nicaea, Holy Trinity theory was publicly acclaimed; as a result, Arius was expelled from the council and condemned as heresy. Despite Arianism was denounced as heresy, a substantial group of followers in Egypt still believed in Arius's theory, and their influence in Alexandria was still prevalent. Therefore, dispute was inevitable. For instance, Athanasios of Alexandria, although being acclaimed as a great priest by later theologians, had a bad reputation for brutally suppressing his theological opponents in Alexandria while he was the Patriarch of Alexandria. Nevertheless, as Emperor Constantine, the main supporter of the Nicene Creed, died in 337, Arianist theologians in Alexandria led by Gregory of Cappadocia organized an uprising with the support of street mobs. They soon took over the city and charged Athanasios for being an outlawed priest. As a result, Athanasios was forced to expelled.
