The Martens Clause and War Crimes in Hawai‘i

The term “war crimes” was not coined until 1919 after the First World War ended in Europe. A common misunderstanding is that individuals whose criminal conduct constituted a war crime could only be prosecuted if that conduct arose after 1919. This is not the case because under the principles of international law, war crimes could have been committed since, at least, 1874, when delegates of fifteen European States gathered in Brussels, Belgium, at the request of Russia’s Czar Alexander II, in order to draft an international agreement concerning the laws and customs of war.

An agreement was made, but it wasn’t ratified by the fifteen States. It did, however, lead to the adoption of the Manual of the Laws and Customs of War at Oxford in 1880. Both the Brussels Declaration and the Oxford Manual formed the basis of the two Hague Conventions of 1899 and 1907.

At the Peace Conference held in The Hague, Netherlands in 1899, countries from across the world met in order to codify what was already accepted as customary international law regarding the rules of warfare and occupation, which is known today as international humanitarian law. The cornerstone of international humanitarian law during the occupation of a State is the duty of the occupying State to administer the laws of the occupied State, which is reflected in Article 43 of the 1899 Hague Convention, II.


Article 43 states, “The authority of the legitimate power having actually passed into the hands of the occupant, the latter shall take all steps in his power to re-establish and insure, as far as possible, public order and safety, while respecting, unless absolutely prevented, the laws in force in the country.” This article is a combination of Article 2, “The authority of the legitimate Power being suspended and having in fact passed into the hands of the occupants, the latter shall take all the measures in his power to restore and ensure, as far as possible, public order and safety,” and Article 3, “With this object he shall maintain the laws which were in force in the country in time of peace, and shall not modify, suspend or replace them unless necessary,”  of the 1874 Brussels Declaration. The Brussels Declaration was referenced in the Preamble of the 1899 Hague Convention, II. Article 43 was restated in the 1907 Hague Convention, IV.

The contracting States to the 1899 Hague Convention, II, also recognized that they were codifying customary international law and not creating new law. In its Preamble, it states, “Until a more complete code of the laws of war is issued, the High Contracting Parties think it right to declare that in cases not included in the Regulations adopted by them, populations and belligerents remain under the protection and empire of the principles of international law, as they result from the usages established between civilized nations, from the laws of humanity, and the requirements of the public conscience.” This particular provision of the Preamble has come to be known as the Martens clause. Professor von Martens was the Russian delegate at the 1899 Hague Peace Conference, that recommended this provision be placed in the Preamble after the delegates were unable to agree on the status of civilians who took up arms against the occupying State.

The Commission on the Responsibility of the Authors of the War and on Enforcement of Penalties was established at the Paris Peace Conference in 1919 after World War I. Its role was to investigate the allegations of war crimes and recommend who should be prosecuted. In its report (Pamphlet No. 32, p. 18), the Commission identified 32 war crimes, two of which were “usurpation of sovereignty during military occupation” and “attempts to denationalise the inhabitants of occupied territory.”

Although these crimes were not specifically identified in 1899 Hague Convention, II, or the 1907 Hague Convention, IV, the Commission relied solely on the Martens clause in the 1899 Hague Convention, II. In other words, the Commission concluded that the war crimes of “usurpation of sovereignty during military occupation” and “attempts to denationalise the inhabitants of occupied territory” were recognized under principles of international law since at least the 1874 Brussels Declaration.

Under the war crime of usurpation of sovereignty during military occupation, the Commission concluded that from 1915-1918, Bulgaria engaged in criminal conduct when it “Proclaimed that the Serbian State no longer existed, and that Serbian territory had become Bulgarian,” and that “official orders show efforts of Bulgarisation (Pamphlet No. 32, p. 38).” The Commission also concluded Bulgaria committed the following acts of usurpation of sovereignty:

  • Serbian law, courts, and administration ousted
  • Taxes collected under Bulgarian fiscal regime
  • Serbian currency suppressed
  • Public property removed or destroyed, including books, archives and MSS (g., from the National Library, the University Library, Serbian Legation at Sofia, French Consulate at Uskub)
  • Prohibited sending Serbian Red Cross to occupied Serbia

The Commission also concluded that Austrian and German authorities also engaged in the following criminal conduct of usurpation of sovereignty during military occupation from 1915 to 1918 during the occupation of Serbia (Pamphlet No. 32, p. 38).

  • The Austrians suspended many Serbian laws and substituted their own, especially in penal matters, in procedure, judicial reorganization, &c.
  • Museums belonging to the State (g., Belgrade, Detchani) were emptied and the contents taken to Vienna

Under the war crime of attempts to denationalize the inhabitants of occupied territory, the Commission concluded that from 1915-1918, Bulgaria engaged in the following criminal conduct in occupied Serbia (Pamphlet No. 32, p. 39).

  • Efforts to impose their national characteristics on the population
  • Serbian language forbidden in private as well as official relations
  • People beaten for saying “Good morning” in Serbian
  • Inhabitants forced to give their names a Bulgarian form
  • Serbian books banned—were systematically destroyed
  • Archives of churches and law courts destroyed
  • Schools and churches closed, sometimes destroyed
  • Bulgarian schools and churches substituted—attendance at school made compulsory
  • Population forced to be present at Bulgarian national solemnities

The Commission also concluded that Austrian and German authorities also engaged in the following criminal conduct of attempts to denationalize the inhabitants of occupied territory from 1915 to 1918 during the occupation of Serbia (Pamphlet No. 32, p. 39).

  • Austrians and Germans interfered with religious worship, by deportation of priests and requisition of churches for military purposes
  • Interfered with use of Serbian language

The prosecution of German officials and their Allies for war crimes committed during World War I, however, was dismal. Of 5,000 individuals reported for war crimes only 12 were tried and 6 were convicted. Despite this failure, it was the beginning of imposing criminal liability on individuals for violations of international law that eventually became firmly grounded after the Second World War, which led to war crimes legislation in countries who were contracting parties to the 1949 Geneva Conventions, and also the establishment of the International Criminal Court.

Under the principles of international law, officials of the United States were capable of committing war crimes when the Hawaiian Kingdom was first invaded on January 17, 1893 and occupied until April 1, 1893; and invaded again and occupied since August 12, 1898 during the Spanish-American War. The criminal conduct committed by German, Austrian and Bulgarian officials against Serbia and its people are very similar to the criminal conduct by the United States after 1898 against the Hawaiian Kingdom and its people.

  1. Its clear that the US has committed war crimes against the subjects and government of the kingdom of Hawai’i particularly as those crimes pertain to the usurpation of the legitimate government of Hawai’i and the denationalization of Hawaiian citizens.

    The US must be held accountable for these war crimes and an immediate remedy must be applied in the form of the immediate, complete, permanent and unconditional US deoccupation of Hawai’i and the restoration of Hawai’i’s lawful government, the Hawaiian monarchy.

    ali’i aloha aina

    • Aloha ponokeali’i, it appears this article is saying that only individuals can be held accountable for violations of humanitarian law (war crimes). I believe the objective is to have the proper entity investigate and recommend these individuals for prosecution.
      If the objective is to get a recommendation for prosecution then it would be wise to provide the prosecutor with irrefutable evidence and facts that the individual(s) knowingly and intentionally committed the crime.
      A recommendation for prosecution would clearly state to the U.S. and entire international community that Hawaii is occupied. That type of ruling can change the dynamics of how other nation states play geopolitics and economics.
      Same way the U.S. will play China if the Philippine’s gets a ruling in their favor by the PCA regarding the South China Sea.
      It’s kinda doing things in reverse to achieve the desire result of holding the U.S. accountable to follow International law. MHO
