The French legal system developed from the influences of Roman and canon law, combined with regional traditions, into a distinctive system. The publications of canon and Roman law evolved gradually into books of distinct French law, written in French instead of in Latin. Lawyers formed an independent class of author that was second in publication only to the Church, and many of the most impressively bound books come from the legal works of this time.
