The Consulate of the Sea (Catalan: Consolat de mar; pronounced [kunsuˈlad də ˈmaɾ]) was a quasi-judicial body set up in the Crown of Aragon, later to spread throughout the Mediterranean basin, to administer maritime and commercial law.
[1] This gave Barcelona merchants the right to settle their commercial disputes without interference from the royal courts: in return, the king received much needed financial support for his wars of expansion.
One of the earliest was in Valencia (1283), where the charter of Peter III of Aragon makes it clear that disputes are to be settled "according to maritime customs, as these are accepted in Barcelona."
The earliest extant printed edition of the work (Barcelona, 1494) is without a title-page or frontispiece, but it is described by the above-mentioned title in the epistle dedicatory prefixed to the table of contents.
[3] The epistle dedicatory states that the work is an amended version of the Book of the Consulate of the Sea, compiled by Francis Celelles with the assistance of numerous shipmasters and merchants well versed in maritime affairs.
