This dimension groups legal systems by the era in which they originated. Wikipedia notes that legal systems vary widely "in their sources of law and the extent to which they are based on formal written law," differences that trace back to when and how each system first took shape. Browsing by origin era lets a visitor compare legal systems that arose in the same period.
