Edelfrei

The term edelfrei or hochfrei ("free noble" or "free knight") was originally used to designate and distinguish those Germanic noblemen from the Second Estate (see Estates of the realm social hierarchy), who were legally entitled to atonement reparation of three times their "Weregild" (Wergeld) value from a guilty person or party. Such knights were known as Edelfreie or Edelinge. This distinguished them from those other free men or free knights who came from the Third Estate social hierarchy, and whose atonement reparation value was the standard "Weregild" (Wergeld) amount set according to regional laws. In the Holy Roman Empire, the "high nobility" ('') emerged from the Edelfreie during the course of the 12th century, in contrast to the so-called ministeriales, most of whom were originally unfree knights or .

In the Middle Ages edelfrei or hochfrei meant, in simple terms, that someone was a member of an ancient, dynastic aristocratic line. Free noble families were independent of legal obligations of a secondary nature, and they were not subordinated to any other families or dynasties, apart from the king or emperor. The modern concept of aristocracy (Uradel) must not be confused with the term edelfrei'', since the former term's scope is much broader: all families that can prove they belonged to the knightly aristocracy by no later than around 1400 (whether originally edelfrei or ministeriales) are counted today as Uradel, i.e., the aristocracy.
