A person who believes in or advocates for arbitration as a method of resolving disputes rather than litigation or violence.
From 'arbitration' (the process of settling disputes through a neutral third party) combined with the suffix '-ist' (one who advocates for or practices). The term emerged in the late 19th century with the international peace movement.
Arbitrationists were radical optimists—they believed international wars could be prevented if nations agreed to submit disputes to neutral judges, an idea that helped inspire the League of Nations and modern international courts.
