Military occupation, also called belligerent occupation or simply occupation, is temporary hostile control exerted by a ruling power's military apparatus over a
sovereign territory that is outside of the legal boundaries of that ruling power's own sovereign territory.
[Eyal Benvenisti. The international law of occupation. Princeton University Press, 2004. , p. 43] The controlled territory is called ''occupied'' territory, and the ruling power is called the ''occupant''. Occupation's intended temporary nature distinguishes it from

for occupied territory to continue to be widely recognized as occupied in cases where the occupant attempts to alter—with or without support or recognition from other powers—the expected temporary duration of the territory's established power structure, namely by making it permanent through annexation (formal or otherwise) and refusing to recognize itself as an occupant. Additionally, the question of whether a territory is occupied or not becomes especially controversial if two or more powers disagree with each other on that territory's status; such disputes often serve as the basis for armed conflicts in and of themselves.
Occupation and the laws of war
A dominant principle that guided combatants through much of history was .
Emer de Vattel
Emmerich de Vattel ( 25 April 171428 December 1767) was a philosopher, diplomat, and jurist.
Vattel's work profoundly influenced the development of international law. He is most famous for his 1758 work ''The Law of Nations''. This work was his ...
, in The Law of Nations (1758), presented an early codification of the distinction between annexation of territory and military occupation, the latter being regarded as temporary, due to the natural right of states to their .
[ According to Eyal Benvenisti's The International Law of Occupation, Second Edition (2012),
The Hague Convention of 1907 codified these customary laws, specifically within "Laws and Customs of War on Land" (Hague IV); 18 October 1907: "Section III Military Authority over the territory of the hostile State".] The first two articles of that section state:
Art. 42.
Territory is considered occupied when it is actually placed under the authority of the hostile army.
The occupation extends only to the territory where such authority has been established and can be exercised.
Art. 43.
The authority of the legitimate power having in fact passed into the hands of the occupant, the latter shall take all the measures in his power to restore, and ensure, as far as possible, public order and safety, while respecting, unless absolutely prevented, the laws in force in the country.
In 1949 these laws governing the occupation of an enemy state's territory were further extended by the adoption of the Fourth Geneva Convention
The Convention relative to the Protection of Civilian Persons in Time of War (), more commonly referred to as the Fourth Geneva Convention and abbreviated as GCIV, is one of the four treaties of the Geneva Conventions. It was adopted in August 1 ...
(GCIV). Much of GCIV is relevant to protected civilians in occupied territories and Section III: Occupied territories is a specific section covering the issue. Under GCIV, protected civilians in general are:
* those . This generally refers to civilians of an enemy state, including refugees, and stateless persons.
* neutral citizens in occupied territory regardless of diplomatic status
* refugee
A refugee, according to the United Nations High Commissioner for Refugees (UNHCR), is a person "forced to flee their own country and seek safety in another country. They are unable to return to their own country because of feared persecution as ...

as defined under Article 70
Nationals of an enemy state not a signatory or acceded to GCIV are not protected by it. Neutral citizens who are in the home territory of a belligerent nation if their country of origin has diplomatic ties or elsewhere outside occupied territory are not protected. Nationals of a co-belligerent (allied) state which holds diplomatic ties with a belligerent nation are excluded from protection in both locations.
On whether the definition of military occupation applies to anywhere else, the 2023 United States Department of Defense
The United States Department of Defense (DoD, USDOD, or DOD) is an United States federal executive departments, executive department of the federal government of the United States, U.S. federal government charged with coordinating and superv ...
(DOD)'s ''Law of War Manual'' states The DOD's statement is consistent with the definitions provided by Article 42 of the 1907 Fourth Hague Convention and Article 4 of the Fourth Geneva Convention.
Article 6 of GCIV restricts the length of time that most of the convention applies:
The present Convention shall apply from the outset of any conflict or occupation mentioned in Article 2.
In the territory of Parties to the conflict, the application of the present Convention shall cease on the general close of military operations.
In the case of occupied territory, the application of the present Convention shall cease one year after the general close of military operations; however, the Occupying Power shall be bound, for the duration of the occupation, to the extent that such Power exercises the functions of government in such territory, by the provisions of the following Articles of the present Convention: 1 to 12, 27, 29 to 34, 47, 49, 51, 52, 53, 59, 61 to 77, 143.

(26 June 1945) had prohibited war of aggression (See articles 1.1, 2.3, 2.4) and GCIV Article 47, the first paragraph in Section III: Occupied territories, restricted the territorial gains which could be made through war by stating:
Protected persons who are in occupied territory shall not be deprived, in any case or in any manner whatsoever, of the benefits of the present Convention by any change introduced, as the result of the occupation of a territory, into the institutions or government of the said territory, nor by any agreement concluded between the authorities of the occupied territories and the Occupying Power, nor by any annexation by the latter of the whole or part of the occupied territory.
Article 49 prohibits the forced mass movement of protected civilians out of or into occupied state's territory:
Individual or mass forcible transfers, as well as deportations of protected persons from occupied territory to the territory of the Occupying Power or to that of any other country, occupied or not, are prohibited, regardless of their motive. ... The Occupying Power shall not deport or transfer parts of its own civilian population into the territory it occupies.

of 12 August 1949, and relating to the Protection of Victims of International Armed Conflicts" has additional articles which cover occupation but many countries including the U.S. are not signatory to this additional protocol.
In the situation of a territorial cession as the result of war, the specification of a in the peace treaty merely means that the country in question is authorized by the international community to establish civil government in the territory. The military government of the principal occupying power will continue past the point in time when the peace treaty comes into force, until it is legally supplanted.
is the rule, as stated in ''Military Government and Martial Law'', by William E. Birkhimer, 3rd edition 1914.
Qualification of a territory as occupied
Article 42 under Section III of the 1907 Fourth Hague Convention specifies that a This definition does not rely on a subjective perception, but rather on the of the occupant. Article 2 of the Geneva Conventions indicates that the definition applies to , even if no armed resistance is encountered. The form of administration by which an occupying power exercises government authority over occupied territory is called ''military government''.
There does not have to be a formal announcement of the beginning of a military government, nor is there any requirement of a specific number of people to be in place, for an occupation to commence. Birkhimer writes:
No proclamation of part of the victorious commander is necessary to the lawful inauguration and enforcement of military government. That government results from the fact that the former sovereignty is ousted, and the opposing army now has control. Yet the issuing such proclamation is useful as publishing to all living in the district occupied those rules of conduct which will govern the conqueror in the exercise of his authority. Wellington
Wellington is the capital city of New Zealand. It is located at the south-western tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the third-largest city in New Zealand (second largest in the North Island ...
, indeed, as previously mentioned, said that the commander is bound to lay down distinctly the rules according to which his will is to be carried out. But the laws of war do not imperatively require this, and in very many instances it is not done. When it is not, the mere fact that the country is militarily occupied by the enemy is deemed sufficient notification to all concerned that the regular has been supplanted by a military government. (p. 61)
Concept of effective control
Case-law regarding Article 42 of the 1907 Fourth Hague Convention reveals that interruptions of an occupying power's effective control resulting from insurgents, terrorists or guerrillas that are able to intermittently gain control over areas of the country would be immaterial to the applicability of the law of occupation, and would not alter the legal status of the occupied territory. For example, in 1948 the U.S. Military Tribunal in Nuremberg

held that:
As of 2012, the physical presence of foreign troops, in the form of "boots on the ground", was considered a "'' sine qua non'' requirement of occupation".
