This exhibit marks the 400th anniversary of the publication of Hugo Grotius’s Mare liberum, a short work, originally published as a pamphlet, which produced the first effective argument for the freedom of the seas and, with Grotius’s more mature work, De jure belli ac pacis (1625), lent substance and prestige to the idea of an international law in the service of the common good.

In principle, the Roman Civil Law had already established that navigation on the high seas was open to all. But in practice the principle was frequently disregarded  – even by Rome itself, when its naval power was at its height, and by others after its decline. With the growth of maritime commerce, especially in the later Middle Ages, maritime powers asserted dominion over wide areas of ocean space: Venice to dominion over the Adriatic Sea (Guido Pace, De dominio maris Adriatico, 1619); Genoa the Ligurian (Pietro Battista Borgo, De dominio serenessimae Genuinsis Reipublica in mari Liguria, 1641); Sweden, Denmark and Poland to all or parts of the Baltic.

Early efforts to codify maritime law, such as the 12th century Laws of Oleron and the Consolat de Mar (ca. 1484) had codified admiralty law on a range of subjects, including, for example, ship ownership, discipline and punishment of crews, and salvage.
