Two examples of unilateral annexation laws, both illegal under international law
Annexation,[1] ininternational law, is the forcible acquisition and assertion of legal title over one state's territory by another state, usually followingmilitary occupation of the territory.[2] In current international law, it is generally held to be an illegal act.[3] Annexation is a unilateral act where territory is seized and held by one state,[4] as distinct from the completeconquest of another country,[a][7][8] and differs fromcession, in which territory is given or sold through treaty.
Annexation can belegitimized if generally recognized by other states and international bodies.[4][9][2]
The illegality of annexation means that states carrying out such acts usually avoid using the word annexation in describing their actions;[10][11] in each of the unresolved annexations byIsrael,Morocco andRussia, the states have avoided characterizing their actions as such.[11][12]
These principles were reconfirmed by the 1970Friendly Relations Declaration.[15] Since the use of force against territorial integrity or political independence is illegal, the question as to whethertitle orsovereignty can be transferred in such a situation has been the subject of legal debate.[16] '[A]nnexation by the use of force of the territory of another State or part thereof' is anact of aggression according to the Rome Statute of theInternational Criminal Court.[17]
Illegally annexed territory is considered as still occupied under international law and the provisions of international humanitarian law continue to apply. For precision, such territory may be referred to as "occupied and illegally annexed".[18] In a report to theUnited Nations General Assembly,Michael Lynk contrasted de jure annexation as a formal declaration[2] by a state that it is claiming permanent sovereignty over territory and de facto annexation without the formal declaration[3] as a descriptive term for a state establishing facts on the ground as the prelude to a future claim of sovereignty.[19]
TheFourth Geneva Convention (GCIV) of 1949 amplified theHague Conventions of 1899 and 1907 with respect to the question of the protection of civilians,[20] and the rules regarding inviolability of rights have "an absolute character",[21] making it much more difficult for a state to bypass international law through the use of annexation.[21][c]
Annexations since the foundation of the United Nations
During the 1967Six-Day War,Israel capturedEast Jerusalem, a part of theWest Bank, fromJordan. WhileJordan had annexed the West Bank in 1950, it was considered an illegal occupation and Jordan was recognized as the legal sovereign by the United Kingdom and possibly Pakistan. On 31 July 1988, Jordan relinquished this claim. It has remained occupied until the present day. On 27 June 1967, Israel unilaterally extended its law and jurisdiction to East Jerusalem and some of the surrounding area, incorporating about 70 square kilometers of territory into the Jerusalem Municipality. Although at the time, Israel informed theUnited Nations that its measures constituted administrative and municipal integration rather than annexation. Later rulings by the Israeli Supreme Court indicated that East Jerusalem had become part of Israel. In 1980, Israel passed theJerusalem Law as part of itsBasic Law, which declared Jerusalem the "complete and united" capital of Israel. In other words, Israel purported to annex East Jerusalem.[22][23][24] The annexation was declared null and void byUnited Nations Security Council (UNSC) resolutions 252, 267, 271, 298, 465, 476[25] and 478.[26]
Jewish neighborhoods have since been built in East Jerusalem, and Israeli Jews have since also settled in Arab neighborhoods there, though some Jews may have returned from their 1948 expulsion after theBattle for Jerusalem. Only Costa Rica recognized Israel's annexation of East Jerusalem, and those countries who maintained embassies in Israel did not move them to Jerusalem.[27]TheUnited States Congress passed theJerusalem Embassy Act, which recognizes Jerusalem as the united capital of Israel and requires the relocation of the U.S. embassy there in 1995.[28] The act included a provision permitting the President to delay its implementation due to national security concerns. This waiver was used by presidentsClinton,Bush,Obama, andTrump, but was allowed to expire in 2019.[29]
Law professor Omar M. Dajani and others[30][31] discuss de facto annexation (also referred to as "creeping annexation"[32]). The debate considers whether, in all the circumstances, there is a pattern of behavior sufficient to conclude that Israel is in violation of the international prohibition against annexation, even absent a formal declaration.[33]
Israel occupied two-thirds of theGolan Heights fromSyria during the 1967 Six-Day War, and subsequently built Jewish settlements in the area. In 1981, Israel passed theGolan Heights Law, which extended Israeli "law, jurisdiction, and administration" to the area, including theShebaa farms area. This declaration was declared "null and void and without international legal effect" byUnited Nations Security Council Resolution 497. TheFederated States of Micronesia recognized the annexation and in 2019, the United States joined in recognition.
The vast majority ofSyrian Druze inMajdal Shams, the largest Syrian village in the Golan, have held onto their Syrian passports. When Israel annexed the Golan Heights in 1981, 95% of the Majdal Shams residents refused Israeli citizenship, and are still firmly of that opinion, in spite of theSyrian Civil War.[34]
On 29 November 2012, theUnited Nations General Assembly reaffirmed it was "[d]eeply concerned that Israel has not withdrawn from the Syrian Golan, which has been under occupation since 1967, contrary to the relevant Security Council and General Assembly resolutions," and "[s]tress[ed] the illegality of the Israeli settlement construction and other activities in the occupied Syrian Golan since 1967."[35] The General Assembly then voted by majority, 110 in favour to 6 against (Canada, Israel, Marshall Islands, Federated States of Micronesia, Palau, United States), with 59 abstentions, to demand a full Israeli withdrawal from the Syrian Golan Heights.[35]
On 25 March 2019, theUnited Statesrecognized the Golan Heights as sovereign Israeli territory.[36]In response,United Nations Secretary-GeneralAntónio Guterres stated "the status of Golan has not changed",[37][38] and the decision received worldwide condemnation with European members of the United Nations Security Council noting "we raise our strong concerns about the broader consequences of recognizing illegal annexation and also about broader regional consequences" and that "annexation of territory by force is prohibited under international law", adding that unilateral changes to borders violate "the rules-based international order and the UN Charter".[39]
The annexation of Western Sahara occurred in two stages: 1976 and 1979.
In 1975, and following theMadrid Accords betweenMauritania,Morocco, andSpain, the last Spanish troops withdrew from the territory and ceded the administration to Mauritania and Morocco. On 14 April 1976, the two countries annexed it between themselves via the Western Sahara partition agreement. This was challenged by anindependentist movement, thePolisario Front that waged aguerrilla war against both Mauritania and Morocco. On 14 August 1979, after a militaryputsch, Mauritania renounced all territorial claims to Western Sahara and withdrew its troops. This prompted Morocco to extend its annexation to formerly Mauritanian-controlled areas.
AUnited Nations peace process was initiated in 1991, but it has been stalled, and as of mid-2012, the UN is holding direct negotiations between Morocco and the Polisario front to reach a solution to the conflict. TheSahrawi Arab Democratic Republic is apartially recognized state that has claimed the entire region since 1976.
Russia rejects the view that this was an annexation and regards it as an accession to the Russian Federation of astate that had just declared independence from Ukraine following adisputed referendum, and considers itsecession as a result ofirredentism. A term often used in Russia to describe these events is "re-unification" (воссоединение) to highlight the fact that Crimea was a part of theRussian Empire from 1783 to 1917, and part of theRussian SFSR from 1921 to 1954.Few states recognize this view. Ukraine considers Crimea and Sevastopol its own territory, and oversees theCrimea Platform, an international diplomatic initiative to restore its sovereignty.

The part of formerMandatory Palestineoccupied by Jordan during the1948 Arab–Israeli War was renamed "theWest Bank". It was annexed to Jordan in 1950 at the request of a Palestinian delegation.[44] It had been questioned, however, how representative that delegation was, and at the insistence of theArab League, Jordan was considered a trustee only.[45] OnlyPakistan and theUnited Kingdom recognized the annexation by Jordan.[46] It was not condemned by the United Nations Security Council and it remained under Jordanian rule until 1967 when it wasoccupied by Israel. Jordan did not officially relinquish its claim to rule the West Bank until 1988.[47] Israel has not taken the step of annexing the territory (except for the part of it that was made part of the Jerusalem Municipality). Rather, there were enacted a complex (and highly controversial) system ofmilitary government decrees in effect applying Israeli law in many spheres toIsraeli settlements.
South Africande facto annexation of South West Africa
Following an Indonesian invasion in 1975,East Timor (Timor-Leste) was annexed by Indonesia and was known asTimor Timur. It was regarded by Indonesia as the country's 27th province, but this was never recognised by theUnited Nations. The people of East Timor resisted Indonesian forces in a prolonged guerrilla campaign.
Followinga referendum held in 1999 under aUN-sponsored agreement between the two sides, the people of East Timor rejected the offer of autonomy within Indonesia. East Timor achieved independence in 2002 and is now officially known asTimor-Leste.
After being allied withIraq during theIran–Iraq War (largely due to desiring Iraqi protection fromIran),Kuwait wasinvaded andannexed byIraq (underSaddam Hussein) in August 1990. Hussein's primary justifications included a charge that Kuwaiti territory was in fact an Iraqi province, and that annexation was retaliation for "economic warfare" Kuwait had waged throughslant drilling into Iraq's oil supplies. The monarchy was deposed after annexation, and an Iraqi governor installed.
United States presidentGeorge H. W. Bush ultimately condemned Iraq's actions, and moved to drive out Iraqi forces. Authorized by United Nations Security Council resolutions, an American-led coalition of 34 nations fought theGulf War to reinstate theKuwaiti Emir. Iraq's invasion (and annexation) was deemed illegal and Kuwait remains an independent nation today.
Tibet and approximate line ofcommunist advance in February 1950
The rule of theQing dynasty overTibet was established after aQing expedition force defeated theDzungar Khanate which had occupied Tibet in 1720, and lasted until the fall of the Qing dynasty in 1912. TheImperial Edict of the Abdication of the Qing Emperor issued in 1912 provided the legal basis for theRepublic of China (ROC) to inherit all Qing territories, including Tibet.[48][49][50] However, the ROC had no effective control over Tibet from 1912 to 1951;[51] In the opinion of the Chinese government, this condition does not represent Tibet'sde jure independence as many other parts of China also enjoyedde facto independence when the Chinese state was torn bywarlordism,Japanese invasion, andcivil war.[52]
Tibet came under the control of thePeople's Republic of China (PRC) after attempts by theGovernment of Tibet to gain international recognition, efforts to modernize itsmilitary, negotiations between the Government of Tibet and the PRC, anda military conflict in theChamdo area of westernKham in October 1950. Many analysts consider the incorporation of Tibet into the PRC an annexation.[53][54][55]
If the actions of 1950 constituted an annexation, it was subsequently legalized by theSeventeen Point Agreement by the Government of Tibet in October 1951. From 1959 onwards, claims were made that this agreement was signed under pressure; academics have debated this ever since, but Tibet is recognized internationally as part of China.[56][57]
After the withdrawal of the British Empire from India, each of the Princely States of India and Pakistan that had been protectorates of the British Empire were given the choice of either 1. opting to join India, 2. opting to join Pakistan or 3. resume their former status as fully independent states. While most of the princely states opted to join either Pakistan or India,Hyderabad State elected instead to resume full independence. Following the expiration of ultimatums from India, the Indian military launched its Operation Polo on 13 September 1948 and invaded Hyderabad. After conquering most of Hyderabad in five days of warfare, the Nizam signed a treaty on 18 September 1948 that saw Hyderabad annexed by India.
In 1954, the residents ofDadra and Nagar Haveli, a Portugueseenclave within India, ended Portuguese rule with the help of nationalist volunteers. From 1954 to 1961, the territory enjoyedde facto independence. In 1961, the territory was merged with India after its government signed an agreement with the Indian government.
In 1961,India andPortugal engaged in a brief military conflict over Portuguese-controlledGoa andDaman and Diu. India invaded and conquered the areas after 36 hours of fighting, thus ending 451 years of Portuguese colonial rule in India. The action was viewed in India as a liberation of historically Indian territory; in Portugal, however, the loss of both enclaves was seen as a national tragedy. A condemnation of the action by the United Nations Security Council was vetoed by theSoviet Union.[58] Goa and Daman and Diu were incorporated into India.
The strategic importance ofSikkim was realized in the 1960s during theSino-Indian War.Map in Polish.
During theBritish colonial rule in India, Sikkim had an ambiguous status, as an Indianprincely state or as an Indianprotectorate. Prior to Indian independence,Jawaharlal Nehru, acting as the leader of Executive Council, agreed that Sikkim would not be treated as an Indian state. Between 1947 and 1950, Sikkim enjoyedde facto independence. However, Indian independence spurred popular political movements in Sikkim and the rulingChogyal came under pressure. He requested Indian help to quell the uprising, which was offered. Subsequently, in 1950, India signed a treaty with Sikkim bringing it under itssuzerainty, and controlling its external affairs, defence, diplomacy and communications. A state council was established in 1955 to allow for constitutional government under the Sikkimese monarch. Meanwhile, trouble was brewing in the state after theSikkim National Congress demanded fresh elections and greater representation for theNepalese. In the 1967Nathu La and Cho La clashes, Chinese border attacks were repulsed. In 1973, riots in front of the palace led to a formal request for protection from India. The Chogyal was proving to be extremely unpopular with the people. In 1975, theKazi (prime minister) appealed to the Indian Parliament for a change in Sikkim's status so that it could become a state of India. In April, theIndian Army moved into Sikkim, seizing the city ofGangtok and disarming the Palace Guards. A referendum was held in which 97.5% of the voting people (59% of the people entitled to vote) voted to join the Indian Union. A few weeks later, on 16 May 1975, Sikkim officially became the 22nd state of the Indian Union and the monarchy was abolished.[60]
Western New Guinea officially became part of Indonesia through theAct of Free Choice in 1969, supervised by the UN. Based on the New York Agreement (1962) between Indonesia and the Netherlands, the UN held the Act of Free Choice to determine whether Western New Guinea would join Indonesia or not. Through a deliberation of representatives, the majority voted to join, and this result was accepted by the UN General Assembly in a session in November 1969. This decision was implicitly considered to recognize Western New Guinea as part of Indonesia, because the General Assembly did not reject the report of the UN Secretary General regarding the implementation of Act of Free Choice.[61] West Papua is the western half of the island ofNew Guinea and smaller islands to its west. The separatistFree Papua Movement (OPM) has engaged in a small-scale yet bloody conflict with the Indonesian military since the 1960s.[62]
One example of a claimed annexation afterWorld War II is theKingdom of Norway's southward expansion of thedependent territoryQueen Maud Land. On most maps, there had been an unclaimed area between Queen Maud Land's borders of 1939 and theSouth Pole until 12 June 2015, when Norway formally claimed to have annexed that area.[64]
Lieutenant Commander Desmond Scott hoists theUnion Flag in 1955
On 18 September 1955 at precisely 10:16 am,Rockall was declared officially annexed by theBritish Crown whenLieutenant-Commander Desmond ScottRN,Sergeant Brian PeelRM,Corporal AA Fraser RM, and James Fisher (a civiliannaturalist and former Royal Marine), were deposited on the island by aRoyal Navy helicopter fromHMS Vidal (coincidentally named after the man who first charted the island). The team cemented in a brass plaque on Hall's Ledge and hoisted theUnion Flag to stake the UK's claim.[65] However, any effect of this annexation on valuable maritime rights claims underUNCLOS in the waters beyond 12 nautical miles from Rockall is neither claimed by Britain nor recognised by Denmark (for theFaroe Islands),Iceland orIreland.[citation needed]
^abcRothwell et al. 2014, p. 360: "Annexation is distinct from cession. Instead of a State seeking to relinquish territory, annexation occurs when the acquiring State asserts that it now holds the territory. Annexation will usual follow a military occupation of a territory, when the occupying power decides to cement its physical control by asserting legal title. The annexation of territory is essentially the administrative action associated with conquest. Mere conquest alone is not enough, but rather the conquering State must assert it is now sovereign over the territory concerned. For example, the defeat of Germany and Japan in 1945 led to their occupation by the United States and allies for a number of years, but the States themselves were not absorbed by the Allied Powers part of their respective territories. Examples of annexation in contemporary practice are not common, and are generally viewed as illegal."
^abHofmann 2013, p. i: "Annexation means the forcible acquisition of territory by one State at the expense of another State. It is one of the principal modes of acquiring territory... in contrast to acquisition a) of terra nullius by means of effective occupation accompanied by the intent to appropriate the territory; b) by cession as a result of a treaty concluded between the States concerned (Treaties), or an act of adjudication, both followed by the effective peaceful transfer of territory; c) by means of prescription defined as the legitimization of a doubtful title to territory by passage of time and presumed acquiescence of the former sovereign; d) by accretion constituting the physical process by which new land is formed close to, or becomes attached to, existing land. Under present international law, annexation no longer constitutes a legally admissible mode of acquisition of territory as it violates the prohibition of the threat or use of force. Therefore annexations must not be recognized as legal."

Oxford University Press. p. 289.ISBN978-0-19-878462-3.Conquest and annexation are not synonymous either. The latter term is used within and outside the context of armed conflicts, to designate a unilateral decision adopted by a State in order to extend its sovereignty over a given territory. In many cases, the effective occupation of a terra nullius was followed by a declaration of annexation, in order to incorporate the territory under the sovereignty of the acquiring State. In the context of armed conflicts, annexation is the case in which the victorious State unilaterally declares that it is henceforth sovereign over the territory having passed under its control as a result of hostilities. This attempt at producing a transfer of sovereignty through the exclusive decision of the victor is not generally recognized as valid, both in classical and in contemporary international law. An example of a case of annexation preceding the adoption of the UN Charter is the annexation of Bosnia-Herzegovina by the Austro-Hungarian Empire in 1908. The annexation was not recognized by the major Powers and required a modification of the 1878 Treaty of Berlin which had simply granted Austria-Hungary the right to administer the territory. Another example is the annexation of Ethiopia by Italy in 1936. Examples of purported contemporary annexations are the Golan Heights annexed by Israel in 1980 and Kuwait by Iraq in 1990, both declared null and void by the Security Council, or the incorporation of Crimea and the City of Sebastopol in the Russian Federation.

Retrieved9 March 2022.…today's legal prohibition of conquest creates an incentive for states to obfuscate the reality of annexation that did not exist when such actions were lawful. Excessive formalism, accordingly, seems misplaced when assessing whether a state has manifested an intention to hold a territory "under its dominion" with sufficient clarity to constitute an unlawful annexation. Indeed, state practice offers no shortage of examples in which the international community has looked past a state's formal characterization of its actions when evaluating their lawfulness for this purpose—most recently in relation to Russia's annexation of Crimea. Accordingly, while a formal act of annexation is powerful evidence of intent, the lack of one is by no means dispositive. What other kinds of acts signal such an intention? As noted above, it may be signaled by a state's exercise, for a prolonged time, of the kinds of governmental functions typically reserved to a sovereign. An occupant's refusal to accept the law of occupation's applicability would seem probative for drawing this conclusion—as would a refusal to comply with duties under that law that relate specifically to distinguishing the rights of an occupant from those of a sovereign.
^Hofmann 2013, p. ii: "...States are under a legal obligation to abide by the Stimson Doctrine and not to recognize as lawful territorial changes effected by means of annexation. Moreover, even the annexation of the entire territory of a State does not result in the automatic extinction of that State as a subject of international law notwithstanding that it no longer has the capacity to act as such since it cannot exercise sovereign and effective control over any territory."
