Reglamento y aranceles reales para el comercio libre de España a Indias (1778)

The rulebook that widened Spain's American trade beyond the old fleet system, opening thirteen ports in Spain and the islands to more than twenty in America and abolishing the shipping duties of the 1720 project outright. Read from the Madrid sheets of 1778, it also names its own limits in the same voice: every hull reserved to the king's own subjects, Venezuela left with the Caracas company, and New Spain kept outside the concession altogether.
