The duel in its simplest form is between two individuals. In early ages it was known sometimes as the Judicial Combat, and sometimes as Trial by Battle. Not only points of honor, but titles to land, grave questions of law, and even the subtilties of theology, were referred to this arbitrament, [Footnote: Robertson, History of the Reign of Charles V.: View of the Progress of Society in Europe, Section I. Note XXII.]--just as now kindred issues between nations are referred to Trial by Battle; and the early rules governing the duel are reproduced in the Laws of War established by nations to govern the great Trial by Battle. Ascending from the individual to corporations, guilds, villages, towns, counties, provinces, we find that for a long period each of these bodies exercised what was called "the Right of War." The history of France and Germany shows how reluctantly this mode of trial yielded to the forms of reason and order. France, earlier than Germany, ordained "Trial by Proofs," and eliminated the duel from judicial proceedings, this important step being followed by the gradual amalgamation of discordant provinces in the powerful unity of the Nation,----so that Brittany and Normandy, Franche-Comte and Burgundy, Provence and Dauphiny, Gascony and Languedoc, with the rest, became the United States of France, or, if you please, France. In Germany the change was slower; and here the duel exhibits its most curious instances. Not only feudal chiefs, but associations of tradesmen and of domestics sent defiance to each other, and sometimes to whole cities, on pretences trivial as those which have been the occasion of defiance from nation to nation. There still remain to us Declarations of War by a Lord of Frauenstein against the free city of Frankfort, because a young lady of the city refused to dance with his uncle,--by the baker and domestics of the Margrave of Baden against Esslingen, Reutlingen, and other imperial cities,--by the baker of the Count Palatine Louis against the cities of Augsburg, Ulm, and Rottweil,--by the shoe-blacks of the University of Leipsic against the provost and other members,--and by the cook of Eppstein, with his scullions, dairy-maids, and dish-washers, against Otho, Count of Solms. [Footnote: Coxe, History of the House of Austria. (London, 1820) Ch. XIX., Vol. I. p. 378.] This prevalence of the duel aroused the Emperor Maximilian, who at the Diet of Worms put forth an ordinance abolishing the right or liberty of Private War, and instituting a Supreme Tribunal for the determination of controversies without appeal to the duel, and the whole long list of duellists, whether corporate or individual, including nobles, bakers, shoe-blacks, and cooks, was brought under its pacific rule. Unhappily the beneficent reform stopped half-way, and here Germany was less fortunate than France. The great provinces were left in the enjoyment of a barbarous independence, with the "right" to fight each other.
