Jus naufragii

Charles I of Sicily used it, Philip III of France legislated regulations to cover it, and in the same kingdom Henry II seems to have tolerated it.

When in 1184 a Genoese ship carrying Ibn Jubayr was wrecked off the coast of Messina, it was only by the intervention of William II of Sicily that the passengers were spared robbery and enslavement.

The de facto independent Viscounty of Léon sustained itself on the proceeds of "the most valuable of precious stones", a rock which generated 100,000 solidi per annum in revenue due to shipwrecks.

Several early modern treaties established a time frame during which the owner of the goods wrecked could claim them, typically a year and a day.

England and the Netherlands signed a treaty of alliance 17 September 1625 at Southampton that included a clause allowing the owners of wreckage to reclaim it within a year, and France and the Netherlands signed 27 April 1662 demanding the restitution of shipwrecked goods on the payment of a droit de sauvement, a salvor's fee.

On 12 December 1663 the Netherlands abolished what remained of the old jus—the recht van de tiend penning, or right of the tenth penny.

The French Ordonnance de la Marine (1681) abolished the jus entirely and put castaways under royal protection.
