ABSTRACT
In the half-dozen years after the formal dedication of Constantinople, Constantine would use this new capital city in the east as his normal imperial residence. From here he would direct the administration and defense of the emerging Christian empire he was constructing across the Roman world. His most important actions in these years were his efforts to make Christianity the dominant religion of the state, to establish concord among the bickering bishops in the Church, to conduct campaigns along and to conquer territory above the Danube frontier, and to establish a succession plan and to place his chosen heirs in regional capitals. The emperor would be successful in most of these endeavors, and he would be able to enjoy a magnificent Tricennalia festival in July 336 at Constantinople for his thirty years of rule over the Roman Empire.1
