From Custom to Court: The Evolution of Mediation in European Legal Systems

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article traces how European mediation has repeatedly rebalanced three variables—(1) the source of mediator authority, (2) the degree of institutionalization, and (3) the operative meaning of voluntariness—from antiquity to the present. Using three periods—Proto‐Mediation (c. 500 BCE–c. 1750), Classical Mediation (c.
