The phrase "Great Ordinance" was also an early term for artillery, more usually spelt "Great Ordnance".
In French political history, a great ordinance or grand ordinance (French – Grande ordonnance) was an important royal ordinance or decree. The French Estates-General might also adopt one to, for example, grant the king the exclusive right to raise troops, and establish the taxation measure known as the taille in support of a standing army.
Examples included:
the Grande ordonnance pour la réforme du royaume (the Great Ordinance for the reform of the kingdom): Louis IX forbade blasphemy, gaming, prostitution, tourneys, and trial by ordeal, made the circulation of the royal coin compulsory, and delegated the administration of royal justice to jurists (the origin of the French parliament).
the Grande ordonnance des Eaux et Forêts (Grand Ordinance of the Waters and Forests) of 1516, by which Francis I regulated the management of his domain and of the hunt – this ordinance was revived in 1669.
