 Roman law was progressively abandoned during the early Middle Ages.The Theodosian Code and excerpts of latter-day imperial enactments ("constitutiones") were well known in the successor Germanic states and vital to maintaining the commonplace principle of folk-right which applied pre-existing Roman law to Roman provincials and Germanic law to Germans.The "Breviary of Alaric" and the "Lex Gundobada Romana" are two of the several hybrid Romano-Germanic law codes that incorporated much Roman legal material.
