““Almost all modern legal practice is derived from one of two distinct traditions. The first, the so-called civil law tradition, is a direct successor to the jurisprudence of the Roman Empire, and it dominates most of the legal systems of continental Europe; the second is the institution known as the common law, used in Britain and its former colonies. The divergence between the two dates from the eleventh century, when the only surviving copy of the complete reworking of Roman law known as the Codex Justinianus was discovered in an Italian monastery and percolated throughout Europe.””
