Louis XIV was angered by Anna Maria Luisa's marriage to his sworn foe. Cosimo, after much coaxing, persuaded him otherwise. On 9 October 1691, France, England, Spain, and the United Provinces guaranteed the neutrality of the Tuscan port of Livorno. The Empire, meanwhile, was attempting to extract feudal dues from Cosimo, and ordering him to ally with Austria. The Grand Duke replied that if he did so France would send a naval fleet from Toulon to occupy his state; the Emperor reluctantly accepted this excuse. Tuscany was not alone in its feudal ties to the Empire: The rest of Italy was also bound to pay the Emperor, but at a much higher magnitude than Cosimo, who merely paid on his few undisputed Imperial fiefs.
