where did the council of nicea take place
First Council of Nicaea The council was formally opened 20 May, in the central structure of the imperial palace at Nicaea, with preliminary discussions of the Arian question. Emperor Constantine arrived nearly a month later on 14 June.[39] In these discussions, some dominant figures were Arius, with several adherents. "Some 22 of the bishops at the council, led by Eusebius of Nicomedia, came as supporters of Arius. But when some of the more shocking passages from his writings were read, they were almost universally seen as blasphemous."[5] Bishops Theognis of Nicaea and Maris of Chalcedon were among the initial supporters of Arius.
