The paper aims to analyse the legislative process that brought the Christianism to become the main religion of the Roman Empire. The transition of the Empire from Paganism to Christianism was gradual and it began with issuing the 'Edict of Milan' by Constantin in 313 A.D. From this moment on the Christian communities would have definitely become legitimate. During the following years several laws were progressively issued in order to restrict the paganism and its practises, until the occurrence of a definitive persecution of pagan people in the last years of the Fourth Century. The present article analyses this process and tries to find the normative grounding that led to the triumph of the Christianism over the Paganism.
