Ecclesiastical provinces first corresponded to the civil provinces of the Roman Empire. From the second half of the 2nd century, the bishops of these provinces were accustomed to assemble on important occasions for common counsel in synods. From the end of that century the summons to attend these increasingly important synods was usually issued by the bishop of the capital or metropolis of the province, who also presided over the assembly, especially in the East. Important communications were also forwarded to the bishop of the provincial capital to be brought to the notice of the other bishops. Thus in the East during the 3rd century the bishop of the provincial metropolis came gradually to occupy a certain superior position, and received the name of metropolitan.
