Constantinian Dynasty
The Constantinian dynasty properly began with Constantius "Chlorus" (caesar, 293, augustus, 305), an experienced Illyrian soldier and general; the Constantiniani were originally another family of "Barracks Emperors". The dynasty retained and reinforced the monarchical evolution of the Imperial dignity, and sponsored the pivotal Edict of Milan in 312, which extended official toleration to Christianity, which religion had suffered considerable persecution under recent Emperors. Constantine I undertook major reforms of Imperial administration and military organisation, founded a new Imperial capital at Constantinople on November 8, 324, summoned the first Christian ecumenical council (I Nicaea, 325), and became the first Christian Emperor in 337.
