This paper explores the way arbitration approaches developed through the first four stages of rule development, focusing in turn on the ways the popularity of wagering first created more need for formally signed ‘articles of agreement’ for each match, and then the inclusion of arbitration and judgement methods in the emerging early forms of rules. It then shows the way various official roles evolved over time alongside broader rule developments: the need for ‘umpires’ in cricket, pugilism, and some other sports; the role of ‘tryers’, ‘judges’ and ‘stewards’ in horse racing; arbitration through expertise, experience, and status in cockfighting; and the rare attempts to take appeals beyond the immediate game. It then explores how these official roles developed from the early nineteenth century onwards, as national organizations grew in power, and how a new role, the neutral ‘referee’, was created to arrive at a solution when umpires or others disagreed. Changes in later nineteenth-century rugby and soccer illustrate the way the then new forms of football followed earlier processes in moving towards more neutral forms of arbitration.
