  Virtually all countries in the 21st century have criminal law grounded in civil law, common law, Islamic law, or socialist law. Historically, criminal codes have often divided criminals by class or caste, prescribing different penalties depending on status. In some tribal societies, an entire clan is recognized as liable for a crime. In many cases, disputes over a crime in this system lead to a feud that lasts over several generations.
