The Twelve Tables
Subpoena, habeas corpus, pro bono, affidavit—all these terms derive from the Roman legal system, which dominated Western law and government for centuries. The basis for early Roman law came from the Twelve Tables, a code that formed an essential part of the constitution during the Republican era. First adopted around 450 B.C., the Twelve Tables detailed laws regarding property, religion and divorce and listed punishments for everything from theft to black magic.
Established by the Byzantine emperor Justinian between 529 and 535 A.D., the Corpus Juris included modern legal concepts such as the notion that the accused is innocent until proven guilty. Aiming to clarify and update the old Roman laws, eradicate inconsistencies and speed up legal processes, the collection of imperial edicts and expert opinions covered all manner of topics from punishments for specific crimes to marriage and the inheritance of property. After the fall of the Roman empire, it became the basis for many of the world’s legal systems. Along with English common law and sharia law, Roman law remains hugely influential and is still reflected in the civil laws of several European nations as well as the U.S. state of Louisiana.
