The Order of the Golden Fleece was established January 10, 1430, by Philip the Good, Duke of Burgundy, in celebration of the prosperous and wealthy domains united in his person that ran from Flanders to Switzerland. It is restricted to a limited number of knights, initially 24 but increased to 30 in 1433, and 50 in 1516, plus the sovereign.[1] It received further privileges unusual to any order of knighthood: the sovereign undertook to consult the order before going to war; all disputes between the knights were to be settled by the order; at each chapter the deeds of each knight were held in review, and punishments and admonitions were dealt out to offenders, and to this the sovereign was expressly subject; the knights could claim as of right to be tried by their fellows on charges of rebellion, heresy and treason, and Charles V conferred on the order exclusive jurisdiction over all crimes committed by the knights; the arrest of the offender had to be by warrant signed by at least six knights, and during the process of charge and trial he remained not in prison but in the gentle custody of his fellow knights. The order, conceived in an ecclesiastical spirit in which mass and obsequies were prominent and the knights were seated in choirstalls like canons,[2] was explicitly denied to "heretics", and so became an exclusively Catholic award during the Reformation.
