Corpus Juris Civilis
Under the reign of Justinian I it was Tribonian, a notable jurist, who supervised the revision of the legal code known today as the "Corpus Juris Civilis". Justinian's reforms had a clear effect on the evolution of jurisprudence, with his "Corpus Juris Civilis" becoming the basis for revived Roman law in the Western world, while Leo III's "Ecloga" influenced the formation of legal institutions in the Slavic world.
