Since the month of August, 1914, the expression “Freedom
of the Seas” has been on the lips alike of belligerent
and neutral, and it seems as advisable as it is timely to
issue—for the first time in English—the famous Latin
tractate of Grotius proclaiming, explaining, and in no small
measure making the “freedom of the seas.”[A]
The title of the little book, first published, anonymously,
in November, 1608, explains the reason for its composition:
“The Freedom of the Seas, or the Right which belongs to
the Dutch to take part in the East Indian trade.” It was
an open secret that it was written by the young Dutch
scholar and lawyer, Hugo Grotius. It was a secret and
remained a secret until 1868 that the Mare Liberum was
none other than Chapter XII of the treatise De Jure
Praedae, written by Grotius in the winter of 1604-5, which
first came to light in 1864 and was given to the world four
years later.[B]
The publication of the treatise on the law of prize is
important as showing that the author of the Mare Liberum
was already an accomplished international lawyer, and it
proves beyond peradventure that the masterpiece of 1625
on the “Law of War and Peace” was not a hurried production,
but the culmination of study and reflection extending
over twenty years and more. More important
still is the fact that neither the law of prize nor the Mare
Liberum was a philosophic exercise, for it appears that
Grotius had been retained by the Dutch East India Company
to justify the capture by one of its ships of a Portuguese
galleon in the straits of Malacca in the year 1602;
that the treatise on the law of prize, of which the Mare
Liberum is a chapter, was in the nature of a brief; and that
the first systematic treatise on the law of nations—The Law
of War and Peace—was not merely a philosophical disquisition,
but that it was the direct outgrowth of an actual case
and of professional employment.[C]
The Spaniards, as is well known, then claimed the
Pacific Ocean and the Gulf of Mexico, and Portugal
claimed, in like manner, the Atlantic south of Morocco and
the Indian Ocean, and both nations, at this time under a
common sovereign, claimed and sought to exercise the right
of excluding all foreigners from navigating or entering
these waters. The Dutch, then at war with Spain, although
not technically at war with Portugal, established themselves
in 1598 in the island of Mauritius. Shortly thereafter they
made settlements in Java and in the Moluccas. In 1602
the Dutch East India Company was formed, and, as it attempted
to trade with the East Indies, its vessels came into
competition with those of the Portuguese engaged in the
Eastern trade, which sought to exclude them from the
Indian waters. One Heemskerck, a captain in the employ
of the Company, took a large Portuguese galleon in the
Straits of Malacca. To trade with the East Indies was one
thing, to capture Portuguese vessels was quite another thing.
Therefore, some members of the Company refused their
parts of the prize; others sold their shares in the company,
and still others thought of establishing a new company in
France, under the protection of King Henry IV, which
should trade in peace and abstain from all warlike action.
The matter was therefore one of no little importance, and
it appears that Grotius was consulted and wrote his treatise
on the law of prize, which is in the nature of a brief and
is, at any rate, a lawyer’s argument.[D]
In 1608 Spain and Holland began negotiations which,
on April 9, 1609, resulted in the truce of Antwerp for the
period of 12 years, and, in the course of the negotiations,
Spain tried to secure from the United Provinces a renunciation
of their right to trade in the East and West Indies.
The Dutch East India Company thereupon, it would appear,
requested Grotius to publish that part of his brief dealing
with the freedom of the seas. This was done under the
title of Mare Liberum, with such changes as were necessary
to enable it to stand alone.
It will be observed that the Mare Liberum was written
to refute the unjustified claims of Spain and Portugal to
the high seas and to exclude foreigners therefrom. The
claims of England, less extensive but not less unjustifiable,
were not mentioned, and yet, if the arguments of Grotius
were sound, the English claims to the high seas to the south
and east of England, as well as to undefined regions to
the north and west, would likewise fall to the ground.
Therefore the distinguished English lawyer, scholar, and
publicist, John Selden by name, bestirred himself in behalf
of his country and wrote his Mare Clausum in 1617 or 1618,
although it was not published until 1635, to refute the little
tractate, Mare Liberum.[E] In the dedication to King Charles I,
Selden said: “There are among foreign writers, who
rashly attribute your Majesty’s more southern and eastern
sea to their princes. Nor are there a few, who following
chiefly some of the ancient Caesarian lawyers, endeavor to
affirm, or beyond reason too easily admit, that all seas are
common to the universality of mankind.” The thesis of
Selden was twofold: first, “that the sea, by the law of
nature or nations, is not common to all men, but capable
of private dominion or property as well as the land”;
second, “that the King of Great Britain is lord of the sea
flowing about, as an inseparable and perpetual appendant
of the British Empire.”
In this battle of books, to use the happy expression of
Professor Nys, the Dutch Scholar has had the better of his
English antagonist. If it cannot be said that Grotius wears
his learning “lightly like a flower”, the treatise of Selden
is, in comparison, over-freighted with it; the Mare Liberum
is still an open book, the Mare Clausum is indeed a closed
one, and as flotsam or jetsam on troubled waters, Chapter
XII of the Law of Prize rides the waves, whereas its rival,
heavy and water-logged, has gone under.
In the leading case of The Louis (2 Dodson 210), decided
in 1817, some two hundred years after Selden’s book
was written, Sir William Scott, later Lord Stowell and one
of Selden’s most distinguished countrymen, said, in rejecting
the claim of his country to the exercise of jurisdiction
beyond a marine league from the British shore:
I have to observe, that two principles of public law
are generally recognized as fundamental.
One is the perfect equality and entire independence
of all distinct states. Relative magnitude creates no
distinction of right; relative imbecility, whether permanent
or casual, gives no additional right to the more
powerful neighbor; and any advantage seized upon
that ground is mere usurpation. This is the great
foundation of public law, which it mainly concerns the
peace of mankind, both in their politic and private
capacities, to preserve inviolate.
The second is, that all nations being equal, all
have an equal right to the uninterrupted use of the
unappropriated parts of the ocean for their navigation.
In places where no local authority exists, where the
subjects of all states meet upon a footing of entire
equality and independence, no one state, or any of its
subjects, has a right to assume or exercise authority
over the subjects of another.
In closing the preface to the Mare Clausum, Selden used
language, which the undersigned quotes, albeit in an inverse
sense, as a fit ending to this subject:
“Other passages there are everywhere of the same kind.
But I enlarge myself too much in a thing so manifest.
Therefore I forbear to light a candle to the sun. Farewell
reader.”
