Grotius Establishes the Concept of International Law Summary

  • Last updated on November 10, 2022

Grotius’s major work, On the Law of War and Peace, is widely considered the first definitive text on international law. It provides a systematic description and prescription of the behavior of national communities, which, he argues, have legal rights as well as duties. The work anticipated the advent of the modern state system after 1648.

Summary of Event

Known as the father of international law, Law;international Huig de Groot, who used the Latinized version of his name, Hugo Grotius, was born to an old and distinguished Dutch family in Delft, Holland, in 1583. Grotius was a child prodigy who wrote Greek and Latin poetry, matriculated at the University of Leiden at age eleven, received a doctor of laws degree from the University of Orléans (France) at fifteen, and was admitted to the Dutch bar at sixteen.

Grotius became his country’s official historiographer at eighteen and legal counsel to the Dutch ruler, Prince Maurice of Nassau Maurice of Nassau , at twenty-one. He continued advancing in public and diplomatic posts until 1618 when, becoming involved in a political-religious controversy, Grotius, along with other senior officials, was arrested and sentenced to life imprisonment in Loevestein fortress for treason.

Yet in March of 1621, with the help of his wife, Maria van Reigersbergh Groot, Maria van Reigersbergh de , and his maid, Grotius managed to escape from the castle where he was held and to flee to France where, at first, he was well received and got the moral and financial support of King Louis XIII Louis XIII[Louis 13];Grotius and . Beginning in 1622, in a Paris suburb, he began drafting his magnum opus in Latin, De jure belli ac pacis libri tres (1625) translated into English as On the Law of War and Peace (1654). Other well-known works by Grotius in law and jurisprudence include Apologeticus eorum qui Hollandiae Westfrisiaeque et vicinis quibusdam natioibus ex legibus praefuerunt Apologeticus eorum qui Hollandiae Westfrisiaeque et vicinis quibusdam natioibus ex legibus praefuerunt (Grotius) (defense of the lawful government of Holland and West Friesland, together with some neighboring provinces, as it was before the change occurring in 1618), Inleidinge tot de Hollandsche Rechts-geleerdheyd(pb. 1631; Introduction to Dutch Jurisprudence, 1845), De jure praede commentarius (wr. c. 1604-1606; Commentary on the Law of Prize and Booty Commentary on the Law of Prize and Booty (Grotius) , 1950), and Mare liberum (1609; The Freedom of the Seas Freedom of the Seas, The (Grotius) , 1916). Yet his great versatility is evidenced by his publications in other fields as well.

In 1631, Grotius returned to Holland in defiance of his outlaw status but was forced to flee the following year. He at first took refuge in Germany but then moved to Stockholm where, in 1634, he was offered the Swedish ambassadorship to Paris. He helped to negotiate the Franco-Swedish Treaty of 1635 and others but was relieved of his post by the newly ascended Queen Christina Christina (queen of Sweden) of Sweden in 1644. In 1645, Grotius returned to Stockholm but declined the alternative employment offered him in the Swedish service. On his way to Rostock, Germany, he was shipwrecked in the Baltic Sea and died of exhaustion two days later on August 28, 1645. Grotius was subsequently buried in his home town of Delft.

On the Law of War and Peace, a work in international law, is an expansion of Grotius’s ideas outlined in his earlier work. The book is premised on his idea of civil society governed by the ius gentium, the law of nations. The latter in turn is based on common natural law, fundamental to human nature and discoverable by human reason. This law of nations should dictate relations between communities not yet organized as units of political society as well as between national states since no community can exist without law. The theme, heralded by a long line of thinkers from classical times on, is developed in Grotius’s three-volume treatise, the original 1625 edition running to 786 pages. It falls into two major parts: first, the legal obligations of human societies, including those with sovereign power; and second, how to enforce such obligations and punish violations of law—vital features of Grotius’s message. This message declares that communities have legal rights and duties, and that war is a law-enforcement procedure similar to judicial remedies.

Book 1 (five chapters) of On the Law of War and Peace inquires whether war is ever justified. Grotius’s answer, contradicting pacifist opinion and many Christian theologians, is that it is justified when an injury of some sort is the cause. Book 2 (twenty-six chapters) holds that there can therefore be as many just causes of war as there are types of injuries. Grotius also admonishes against going to war too hastily, even for just cause, and recommends conferences and arbitrations, even contests among the leaders themselves, as preferred alternative methods of settling disputes. To reach his conclusions, Grotius reviewed the entire gamut of substantive rights under municipal law, for “there is a common law among nations, which is valid alike for war and in war.” Book 3 (twenty-five chapters) deals with the actual conduct of war, that is, the humanitarian rules that belligerents must observe during hostilities. Grotius’s counsels of moderation flow from his basic belief in rights common to all humans, which were often ignored in the barbarities of the Thirty Years’ War.

The work abounds in references to the Bible, ancient orators and statesmen, classical historians, philosophers, even poets, but avoids contemporaneous controversial matters. Many of the references are to establish historical authenticity or clarity but some are for adornment. Whatever the purpose, the influence of Greek, Roman, and medieval thinking on Grotius’s formulation of international law is unmistakable.

Significance

The elaboration of “rules” in On the Law of War and Peace by Grotius could not have come at a better time. For the bloody Thirty Years’ War leading to the Peace of Westphalia in 1648 transformed numerous petty principalities into separate sovereign states. Grotius’s great work provided a body of laws to regulate their relations.

In addition to the timing of his writing, Grotius’s persona and his scholarly reputation contributed to the success of his treatise. Another factor in this success was his Dutch heritage. Holland was one of the dominant countries of Europe that had spearheaded the idea of the nation-state. It is not surprising, then, that since its publication, the book crafted by the one dubbed “the wonder of Holland” and “the jurisconsult of humankind” has gone through about one hundred editions and numerous translations.
