Internal border control

<h2 id="background">Background</h2> <p class="note">Further information: <a href="/facts/Travel_document/mTyF0Smk">Travel document § Internal travel documents</a></p> <p>Internal border controls are measures implemented to control the flow of people or goods within a given country. Such measures take a variety of forms ranging from the imposition of border checkpoints to the issuance of internal travel documents and vary depending on the circumstances in which they are implemented. Circumstances resulting in internal border controls include increasing security around border areas (e.g. internal checkpoints in America or Bhutan near border regions), preserving the autonomy of autonomous or minority areas (e.g. border controls between Peninsular Malaysia, Sabah, and Sarawak; border controls between Hong Kong, Macau, and mainland China), preventing unrest between ethnic groups (e.g. Northern Ireland's peace walls, border controls in Tibet and Northeastern India), and disputes between rival governments (e.g. between the <a href="/facts/Republic_of_China/VcJoUD8w">Republic of China</a> and the <a href="/facts/People%2527s_Republic_of_China/lTjIXY5p">People's Republic of China</a>). </p><p>During the <a href="/facts/COVID-19_pandemic/0xTsh7Ut">COVID-19 pandemic</a>, temporary internal border controls were introduced in jurisdictions across the globe. For instance, travel between Australian states and territories was prohibited or restricted by state governments at various points of the pandemic either in conjunction with sporadic lockdowns or as a stand-alone response to COVID-19 outbreaks in neighbouring states.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a><a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a><a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> Internal border controls were also introduced at various stages of Malaysia's <a href="/facts/Malaysian_movement_control_order/0WVUS2U6">Movement Control Order</a>, per which interstate travel was restricted depending on the severity of ongoing outbreaks. Similarly, internal controls were introduced by national authorities within the Schengen Area, though the <a href="/facts/European_Union/6GYcR8qM">European Union</a> ultimately rejected the idea of suspending the <a href="/facts/Schengen_Agreement/ghYHPqx0">Schengen Agreement</a> per se.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a><a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p> <h2 id="examples">Examples</h2> <h3>Asia</h3> <p>Internal border controls exist in many parts of Asia.

There are arrangements exist for travel between territories controlled by the <a href="/facts/Republic_of_China/VcJoUD8w">Republic of China</a> and territories controlled by the <a href="/facts/People%2527s_Republic_of_China/lTjIXY5p">People's Republic of China</a>. <a class="footnote-ref" id="fnref:23" href="#fn:23"><sup>23</sup></a> </p><p>More generally, authorities in <a href="/facts/Mainland_China/HFXJcUky">mainland China</a> maintain a system of residency registration known as <i><a href="/facts/Hukou_system/Q8g0fp9g">hukou</a></i> (<a href="/facts/Chinese_language/771ruUY1">Chinese</a>: 户口; lit. 'household individual'), by which government permission is needed to formally change one's place of residence. It is enforced with <a href="/facts/Resident_Identity_Card/gP2SRcdh">identity cards</a>. This system of internal border control measures effectively limited internal migration before the 1980s but subsequent market reforms caused it to collapse as a means of migration control. An estimated 150 to 200 million people are part of the "blind flow" and have unofficially migrated, generally from poor, rural areas to wealthy, urban ones. However, unofficial residents are often denied official services such as education and medical care and are sometimes subject to both social and political <a href="/facts/Discrimination/B2M2HqxR">discrimination</a>. In essence, the denial of social services outside an individual's registered area of residence functions as an internal border control measure geared toward dissuading migration within the mainland. </p> <h4>Bhutan</h4> <p>Meanwhile, in Bhutan, a microstate accessible by road only through India, there are interior border checkpoints (primarily on the <a href="/facts/Lateral_Road/07u8FNMc">Lateral Road</a>) and, additionally, certain areas require <a href="/facts/Visa_policy_of_Bhutan/hD716vkw">special permits</a> to enter, whilst visitors not proceeding beyond the border city of <a href="/facts/Phuentsholing/zNH00MDW">Phuentsholing</a> do not need permits to enter for the day (although such visitors are <a href="/facts/De_facto/3Du6WQKh">de facto</a> subject to Indian visa policy since they must proceed through <a href="/facts/Jaigaon/yGrzG2Aa">Jaigaon</a>). Individuals who are not citizens of India, Bangladesh, or the Maldives must obtain both their visa and any regional permits required through a licensed tour operator prior to arriving in the country. Citizens of India, Bangladesh, and the Maldives may apply for regional permits for restricted areas online.<a class="footnote-ref" id="fnref:24" href="#fn:24"><sup>24</sup></a> </p> <h4>Vietnam</h4> <p>The <a href="/facts/H%25E1%25BB%2599_kh%25E1%25BA%25A9u/7nIPPwo0">Hộ khẩu</a> system in Vietnam is similar to the Hukou system in mainland China. Local authorities issue each household a "household registration book" or <i>sổ hộ khẩu</i>, in which the basic biographical information of each household member is recorded. The <i>sổ hộ khẩu</i> is the ultimate legal proof of residence in Vietnam. Together with the "citizen identification card" or <i>giấy chứng minh nhân dân/căn cước công dân</i>, the <i>sổ hộ khẩu</i> constitutes the most important legal identification document in Vietnam. Modelled after the Chinese <i><a href="/facts/Hukou/Q8g0fp9g">hukou</a></i> system and originally used in urban areas only, <i>hộ khẩu</i> functioned as a way to manage urban growth and limit how many people moved, as well as who moved in and out of the cities.<a class="footnote-ref" id="fnref:25" href="#fn:25"><sup>25</sup></a> Gradually, the system became a universal method of control as its application expanded to the countryside.<a class="footnote-ref" id="fnref:26" href="#fn:26"><sup>26</sup></a> Presently, the system defines four types of residence, KT1 through KT4. KT1 is the primary and permanent type of residence and denotes a person's primary residential address. People moving on a semi-permanent basis to another place within the same province or national municipality (within Saigon, for example) need to register for a KT2 residential status at that new address. If this same move happens across provincial borders, then the person has to sign up for a KT3 registration. For migrant workers and students temporarily residing outside of their province or national municipality of permanent residence, they need to apply for a KT4 registration.<a class="footnote-ref" id="fnref:27" href="#fn:27"><sup>27</sup></a> Navigating this matrix of regulations is tough. But the public security apparatus that manages the <i>hộ khẩu</i> system is also difficult to deal with, especially if one is a poor migrant worker with little to no formal education. Yet <i>hộ khẩu</i> remains absolutely crucial, especially for the poor. It is tied to access to welfare benefits, and, in the case of children, the right to attend public school.<a class="footnote-ref" id="fnref:28" href="#fn:28"><sup>28</sup></a> For a migrant family in Saigon with no KT3 or KT4 registration, subsidised medical care, poverty assistance, and almost-free schooling are all out of reach.<a class="footnote-ref" id="fnref:29" href="#fn:29"><sup>29</sup></a> Much like its counterpart in mainland China, the denial of services outside an individual's place of registered residence resulting from this system of internal border control serves to dissuade internal migration. </p> <h4>Malaysia</h4> <p>The <a href="/facts/Malaysia/8zbUMzCP">Malaysian</a> states of <a href="/facts/Sabah/bfYrmM2J">Sabah</a> and <a href="/facts/Sarawak/jLxI3WQo">Sarawak</a>, have maintained their own border controls<a class="footnote-ref" id="fnref:30" href="#fn:30"><sup>30</sup></a> since joining Malaysia in 1963. The internal border control is asymmetrical; while Sabah and Sarawak impose immigration control on Malaysian citizens from other states, there is no corresponding border control in <a href="/facts/Peninsular_Malaysia/88WtYx31">Peninsular Malaysia</a>, and Malaysians from Sabah and Sarawak have unrestricted right to live and work in the Peninsular. For social and business visits less than three months, Malaysian citizens may travel between the Peninsular, Sabah and Sarawak using the <a href="/facts/Malaysian_identity_card/jHuEU5GM">Malaysian identity card</a> (MyKad) or <a href="/facts/Malaysian_passport/UyxuIINV">Malaysian passport</a>, while for longer stays in Sabah and Sarawak they are required to have an Internal Travel Document or a passport with the appropriate residential permit. </p> <h4>North Korea</h4> <p>The most restrictive internal border controls are in <a href="/facts/North_Korea/Q41laakP">North Korea</a>. Citizens are not allowed to travel outside their areas of residence without explicit authorisation, and access to the capital city of Pyongyang is heavily restricted.<a class="footnote-ref" id="fnref:31" href="#fn:31"><sup>31</sup></a><a class="footnote-ref" id="fnref:32" href="#fn:32"><sup>32</sup></a> Similar restrictions are imposed on tourists, who are only allowed to leave Pyongyang on government-authorised tours to approved tourist sites. </p> <h4>Israel</h4> <p>The <a href="/facts/Israel_Defense_Forces/9hPaqcAM">Israeli military</a> maintains an intricate network of internal border controls within Israeli and <a href="/facts/State_of_Palestine/WWcc0vRx">Palestinian territory</a> restricting the <a href="/facts/Palestinian_freedom_of_movement/uqD5kzV5">freedom of movement of Palestinians</a>, composed of <a href="/facts/Israeli_checkpoint/T8HPsIK1">permanent, temporary, and random manned checkpoints</a> in the <a href="/facts/West_Bank/xzTTVNJl">West Bank</a>; the <a href="/facts/West_Bank_Barrier/9und9yno">West Bank Barrier</a>; and restrictions on the usage of roads by Palestinians.<a class="footnote-ref" id="fnref:33" href="#fn:33"><sup>33</sup></a> Spread throughout the <a href="/facts/Israel/dEe3IcaY">State of Israel</a> and the areas of the <a href="/facts/State_of_Palestine/WWcc0vRx">State of Palestine</a> under <i><a href="/facts/De_facto/3Du6WQKh">de facto</a></i> Israeli control, internal border control measures are a key feature of Israeli and Palestinian life and are among the most restrictive in the world. Additionally, the <a href="/facts/Blockade_of_the_Gaza_Strip/AxDFH2Cd">blockade</a> of the <a href="/facts/Gaza_Strip/GodcCxlV">Gaza Strip</a> results in a de facto domestic customs and immigration border for Palestinians. In order to clear internal border controls, Palestinians are required to <a href="/facts/Israeli_permit_regime_in_the_West_Bank/JLzWzfsB">obtain a variety of permits</a> from Israeli authorities depending on the purpose and area of their travel. The legality and impact of this network of internal border controls is controversial. <a href="/facts/B%2527Tselem/K34tzg0T">B'Tselem</a>, an Israeli <a href="/facts/Non-governmental_organisation/qxQSsxsI">non-governmental organisation</a> that monitors <a href="/facts/Human_rights/WMW5XCdM">human rights</a> in Palestine, argues that they breach the rights guaranteed by the <a href="/facts/International_Covenant_on_Economic%2c_Social_and_Cultural_Rights/cb0LgRj1">International Covenant on Economic, Social and Cultural Rights</a>—in particular, the right to a livelihood, the right to an acceptable standard of living, the right to satisfactory nutrition, clothing, and housing, and the right to attain the best standard of physical and mental health.<a class="footnote-ref" id="fnref:34" href="#fn:34"><sup>34</sup></a> B'Tselem also argues that the restrictions on ill, wounded and pregnant Palestinians seeking acute medical care is in contravention of international law that states that medical professionals and the sick must be granted open passage.<a class="footnote-ref" id="fnref:35" href="#fn:35"><sup>35</sup></a> While <a href="/facts/Israeli_Supreme_Court/BcqcvxVQ">Israeli Supreme Court</a> has deemed the measures acceptable for security reasons, <i>Haaretz</i>'s <a href="/facts/Amira_Hass/WGgUp56K">Amira Hass</a> argues this policy defies one of the principles of the Oslo Accords, which states that Gaza and the West Bank constitute a single geographic unit.<a class="footnote-ref" id="fnref:36" href="#fn:36"><sup>36</sup></a> </p> <h4>Gallery</h4> <h3>Europe</h3> <p>An example from Europe is the implementation of border controls on travel between <a href="/facts/Svalbard/7Q2MHDKp">Svalbard</a>, which maintains a policy of <a href="/facts/Free_migration/NtY1DFqU">free migration</a> as a result of the <a href="/facts/Svalbard_Treaty/JJ2H3l8D">Svalbard Treaty</a> and the Schengen Area, which includes the rest of Norway. Other examples of effective internal border controls in Europe include the <a href="/facts/Closed_cities/VYTh93hp">closed cities</a> of certain <a href="/facts/Commonwealth_of_Independent_States/DqccXsyS">CIS</a> members, <a href="/facts/Visa_policy_of_Turkmenistan/L2pEhRMx">areas of Turkmenistan</a>[<i>Turkmenistan is not in Europe.</i>] that require special permits to enter, <a href="/facts/Visa_policy_of_Tajikistan/F3px8KBD">restrictions</a> on travel to the <a href="/facts/Gorno-Badakhshan_Autonomous_Region/TelbvRgn">Gorno-Badakhshan Autonomous Region</a> in Tajikistan, and (depending on whether Northern and Southern Cyprus are considered separate countries) the Cypriot border. Similarly, Iraq's <a href="/facts/Iraqi_Kurdistan/lY98mhLE">Kurdistan region</a> maintains a separate and more liberal visa and customs area from the rest of the country, even allowing <a href="/facts/Visa_policy_of_Iraq/YnrtCTVr">visa free entry</a> for Israelis whilst the rest of the country bans them from entering. Denmark also maintains a complex system of subnational countries which, unlike the Danish mainland, are outside the European Union and maintain autonomous customs policies.<a class="footnote-ref" id="fnref:37" href="#fn:37"><sup>37</sup></a> In addition to the numerous closed cities of Russia,<a class="footnote-ref" id="fnref:38" href="#fn:38"><sup>38</sup></a> parts of 19 subjects<a class="footnote-ref" id="fnref:39" href="#fn:39"><sup>39</sup></a> of the Russian Federation are closed for foreigners without special permits and are consequently subject to internal border controls.<a class="footnote-ref" id="fnref:40" href="#fn:40"><sup>40</sup></a> </p> <h4>United Kingdom</h4> <p>Another complex border control situation in Europe pertains to the United Kingdom. Whilst the <a href="/facts/Crown_dependencies/2jUeeK21">crown dependencies</a> are within the <a href="/facts/Common_Travel_Area/sYnaUdE1">Common Travel Area</a>, neither <a href="/facts/Gibraltar/ja2yukgq">Gibraltar</a> nor the sovereign British military exclaves of <a href="/facts/Akrotiri_and_Dhekelia/2RPAL15s">Akrotiri and Dhekelia</a> are. The former maintains its own <a href="/facts/Visa_policies_of_British_Overseas_Territories/6JsKmatF">border control policies</a>, thus requiring physical border security at its border with the Schengen Area as well as the implementation of border controls for travellers proceeding directly between Gibraltar and the British mainland. The latter maintains a relatively open border with Southern Cyprus, though not with Northern Cyprus. Consequently, it is a de facto member of the Schengen Area and travel to or from the British mainland requires border controls. On 31 December 2020, Spain and the United Kingdom reached an agreement in principle under which Gibraltar would join the Schengen Area,<a class="footnote-ref" id="fnref:41" href="#fn:41"><sup>41</sup></a> clearing the way for the European Union and the UK to start formal negotiations on the matter.<a class="footnote-ref" id="fnref:42" href="#fn:42"><sup>42</sup></a> </p><p>In the aftermath of <a href="/facts/Brexit/M80B3fIg">Brexit</a>, border controls for goods flowing between Great Britain and Northern Ireland were introduced in accordance with the <a href="/facts/Northern_Ireland_Protocol/oSC0PmDr">Protocol on Ireland/Northern Ireland</a> agreed to as part of the UK's <a href="/facts/Brexit_withdrawal_agreement/XG5mM0CE">withdrawal agreement</a> with the EU.<a class="footnote-ref" id="fnref:43" href="#fn:43"><sup>43</sup></a> Due to the <a href="/facts/The_Troubles/CvxR8ReG">thirty-year internecine conflict</a> in Northern Ireland, the <a href="/facts/Republic_of_Ireland%25E2%2580%2593United_Kingdom_border/fXuqDstS">UK-Ireland border</a> has had a special status since that conflict was ended by the <a href="/facts/Good_Friday_Agreement/NGphY7YR">Belfast Agreement/Good Friday Agreement</a> of 1998. As part of the <a href="/facts/Northern_Ireland_Peace_Process/TKdt1zyD">Northern Ireland Peace Process</a>, the border has been largely invisible, without any physical barrier or custom checks on its many crossing points; this arrangement was made possible by both countries' common membership of both the <a href="/facts/European_Single_Market/wJDK3gK8">EU's Single Market</a> and <a href="/facts/European_Union_Customs_Union/zklwV2Cu">Customs Union</a> and of their <a href="/facts/Common_Travel_Area/sYnaUdE1">Common Travel Area</a>. Upon the UK's withdrawal from the European Union, the border in Ireland became the only land border between the UK and EU. <a href="/facts/European_Single_Market/wJDK3gK8">EU single market</a> and <a href="/facts/United_Kingdom_Internal_Market_Act_2020/pnatUbCY">UK internal market</a> provisions require certain customs checks and trade controls at their external borders. The Northern Ireland Protocol is intended to protect the EU single market, while avoiding imposition of a '<a href="/facts/Brexit_and_the_Irish_border/PCAutn2a">hard border</a>' that might incite a recurrence of conflict and destabilise the relative peace that has held since the end of <a href="/facts/The_Troubles/CvxR8ReG">the Troubles</a>. Under the Protocol, Northern Ireland is formally outside the EU single market, but <a href="/facts/European_Single_Market/wJDK3gK8">EU free movement of goods</a> rules and <a href="/facts/EU_Customs_Union/zklwV2Cu">EU Customs Union</a> rules still apply; this ensures there are no customs checks or controls between Northern Ireland and the rest of the island.

Even though borders are generally invisible, the existence of areas within the Schengen area but outside the <a href="/facts/European_Union_Value_Added_Tax_Area/6b71cTe2">European Union Value Added Tax Area</a>, as well as jurisdictions such as Andorra which are not officially a part of the Schengen area but can not be accessed without passing through it, has resulted in the existence of sporadic <a href="/facts/Schengen_Area/3x2jdc8H">internal border controls</a> for customs purposes. Additionally, as per Schengen area rules,<a class="footnote-ref" id="fnref:55" href="#fn:55"><sup>55</sup></a> hotels and other types of commercial accommodation must register all foreign citizens, including citizens of other Schengen states, by requiring the completion of a registration form by their own hand. <a class="footnote-ref" id="fnref:56" href="#fn:56"><sup>56</sup></a> The Schengen rules do not require any other procedures; thus, the Schengen states are free to regulate further details on the content of the registration forms, and identity documents which are to be produced, and may also require the persons exempted from registration by Schengen laws to be registered. A Schengen state is also permitted to reinstate border controls with another Schengen country for a short period where there is a serious threat to that state's "public policy or internal security" or when the "control of an external border is no longer ensured due to exceptional circumstances".<a class="footnote-ref" id="fnref:57" href="#fn:57"><sup>57</sup></a> When such risks arise out of foreseeable events, the state in question must notify the European Commission in advance and consult with other Schengen states.<a class="footnote-ref" id="fnref:58" href="#fn:58"><sup>58</sup></a> Since the implementation of the Schengen Agreement, this provision has been invoked frequently by member states, especially in response to the <a href="/facts/European_migrant_crisis/Mp06vFWh">European migrant crisis</a>.<a class="footnote-ref" id="fnref:59" href="#fn:59"><sup>59</sup></a> </p> <h4>Gallery</h4> <h3>North America</h3> <h4>Contemporary</h4> <p class="note">See also: <a href="/facts/Hyder-Stewart_Border_Crossing/dbsoJQqt">Hyder-Stewart Border Crossing</a>, <a href="/facts/Cornwall_Island_(Ontario)/Bg820a2F">Cornwall Island (Ontario)</a>, and <a href="/facts/Akwesasne/xe3eM0EK">Akwesasne</a></p> <p>Multiple types of internal border controls exist in the United States. While the American territories of <a href="/facts/Guam/z77Ql3fM">Guam</a> and the <a href="/facts/Northern_Mariana_Islands/Tb6CPrao">Northern Mariana Islands</a> follow the <a href="/facts/Visa_policy_of_the_United_States/xDE2gzju">same visa policy as the mainland</a>, together, they also maintain their own visa waiver programme for certain nationalities.<a class="footnote-ref" id="fnref:60" href="#fn:60"><sup>60</sup></a> Since the two territories are outside the <a href="/facts/Customs_territory_of_the_United_States/hgVmjTSm">customs territory of the United States</a>, there are customs inspections when travelling between them, and the rest of the U.S. <a href="/facts/American_Samoa/mpcHoegY">American Samoa</a> has its own customs and immigration regulations, thus travelling between it and other American jurisdictions involves both customs and immigration inspections. The <a href="/facts/United_States_Virgin_Islands/VwDBzBGT">Virgin Islands</a> are a special case, falling within the American immigration zone and solely following American visa policy, but being a customs free territory. As a result, there are no immigration checks between the two, but travellers arriving in Puerto Rico or the American mainland directly from the Virgin Islands are subject to border control for customs inspection. The United States also maintains <a href="/facts/United_States_Border_Patrol_interior_checkpoints/dk63Vk96">interior checkpoints</a>, similar to those maintained by Bhutan, along its borders with Mexico and Canada, subjecting people to border controls even after they have entered the country. </p><p>The <a href="/facts/Akwesasne/xe3eM0EK">Akwesasne</a> nation; with territory in <a href="/facts/Ontario/HUkxk5Rf">Ontario</a>, <a href="/facts/Quebec/4hhNvb4t">Quebec</a>, and <a href="/facts/New_York_(state)/mnl67G1G">New York</a>; features several de facto internal border controls. As a result of protests by Akwesasne residents on their rights to cross the border unimpeded, as provided under the 1795 <a href="/facts/Jay_Treaty/W9skFeRu">Jay Treaty</a>, the <a href="/facts/Canada_Border_Services_Agency/pllfeWdH">Canada Border Services Agency</a> closed its post on <a href="/facts/Cornwall_Island_(Ontario)/Bg820a2F">Cornwall Island</a>, instead requiring travellers to proceed to the checkpoint in the city of <a href="/facts/Cornwall%2c_Ontario/c32rPoaz">Cornwall</a>. As a consequence of the arrangement, residents of the island are required to clear border controls when proceeding North to the Ontarian mainland, as well as when proceeding South to Akwesasne territory in New York, thus constituting internal controls both from a Canadian perspective and from the perspective of the Akwesasne nation. Similarly, travelling between Canada and the Quebec portion of the Akwesasne nation requires driving through the state of New York, meaning that individuals will be required to clear American controls when leaving Quebec proper and to clear Canadian border controls when entering Quebec proper, though Canada does not impose border controls when entering the Quebec portion of the Akwesasne nation. Nevertheless, for residents who assert a <a href="/facts/Haudenosaunee/PnYFTuIP">Haudenosaunee</a> national identity distinct from Canadian or American citizenship, the intricate network of Canadian and American border controls are seen as a foreign-imposed system of internal border controls, similar to the Israeli checkpoints in Palestinian territory.<a class="footnote-ref" id="fnref:61" href="#fn:61"><sup>61</sup></a><a class="footnote-ref" id="fnref:62" href="#fn:62"><sup>62</sup></a> </p><p>The city of <a href="/facts/Hyder%2c_Alaska/euAJANmC">Hyder, Alaska</a> has also been subject to internal border controls since America chose to stop regulating arrivals in Hyder from British Columbia. Since travellers exiting Hyder into Stewart, British Columbia are subject to Canadian border controls, it is theoretically possible for someone to accidentally enter Hyder from Canada without their travel documents and then to face difficulties since both America and Canada would subject them to border controls that require travel documents. At the same time, however, the northern road connecting Hyder to uninhabited mountain regions of British Columbia is equipped with neither American nor Canadian border controls, meaning that tourists from Canada proceeding northwards from Hyder are required to complete Canadian immigration formalities when they return to Stewart despite never having cleared American immigration. </p> <h4>Historical</h4> <p class="note">Further information: <a href="/facts/Pass_system_(Canadian_history)/hHypu1kp">Pass system (Canadian history)</a>, <a href="/facts/Slavery_in_the_United_States/CduIa8do">Slavery in the United States</a>, and <a href="/facts/Slavery_in_the_colonial_history_of_the_United_States/9Iqt7cUL">Slavery in the colonial history of the United States</a></p> <p>In the past, internal border control measures were utilised by authorities in North America to control the movements of Indigenous or enslaved persons.

Also known as the natives' law, pass laws severely limited the movements of not only <a href="/facts/Black_people/khyfdI6h">black</a> African citizens, but other people as well by requiring or designated areas. Before the 1950s, this legislation largely applied to African men, and attempts to apply it to women in the 1910s and 1950s were met with significant protests. Pass laws were one of the dominant features of the country's <a href="/facts/Apartheid/8x87W8ex">apartheid</a> system until it was effectively ended in 1986. The first internal passports in South Africa were introduced on 27 June 1797 by the <a href="/facts/George_Macartney%2c_1st_Earl_Macartney/lhDogV7C">Earl Macartney</a> in an attempt to prevent Africans from entering the <a href="/facts/Dutch_Cape_Colony/F9wvTXpj">Cape Colony</a>.<a class="footnote-ref" id="fnref:70" href="#fn:70"><sup>70</sup></a> The Cape Colony was merged with the two Afrikaners republics in southern Africa to form the <a href="/facts/Union_of_South_Africa/bwmp5mXt">Union of South Africa</a> in 1910. By this time, versions of pass laws existed elsewhere. A major boost for their utilization was the rise of the mining sector from the 1880s: pass laws provided a convenient means of controlling workers' mobility and enforcing contracts. In 1896 the <a href="/facts/South_African_Republic/l5gWMsDw">South African Republic</a> brought in two pass laws which required Africans to carry a metal badge. Only those employed by a master were permitted to remain on the Rand. Those entering a "labour district" needed a special pass which entitled them to remain for three days.<a class="footnote-ref" id="fnref:71" href="#fn:71"><sup>71</sup></a> The Natives (Urban Areas) Act of 1923 deemed urban areas in South Africa as "white" and required all black African men in cities and towns to carry around permits called "passes" at all times. Anyone found without a pass would be arrested immediately and sent to a rural area. It was replaced in 1945 by the Natives (Urban Areas) Consolidation Act, which imposed "influx control" on black men and also set up guidelines for removing people deemed to be living idle lives from urban areas. This act outlined requirements for African peoples' "qualification" to reside legally in white metropolitan areas. To do so, they had to have Section 10 rights, based on whether<a class="footnote-ref" id="fnref:72" href="#fn:72"><sup>72</sup></a> </p> <ul><li>the person had been born there and resided there always since birth;</li> <li>the person had laboured continuously for ten years in any agreed area for any employer, or lived continuously in any such area for fifteen years;</li></ul> <p>The Black (Natives) Laws Amendment Act of 1952 amended the 1945 Native Urban Areas Consolidation Act, stipulating that all black people over the age of 16 were required to carry passes and that no black person could stay in an urban area more than 72 hours unless allowed to by Section 10.<a class="footnote-ref" id="fnref:73" href="#fn:73"><sup>73</sup></a> The Natives (Abolition of Passes and Co-ordination of Documents) Act of 1952, commonly known as the Pass Laws Act, repealed the many regional pass laws and instituted one nationwide pass law, which made it compulsory for all black South Africans over the age of 16 to carry the "passbook" at all times within white areas. The law stipulated where, when, and for how long a person could remain.<a class="footnote-ref" id="fnref:74" href="#fn:74"><sup>74</sup></a> </p><p>The document was similar to an <a href="/facts/Internal_passport/nVbfQaq5">internal passport</a>, containing details on the bearer such as their fingerprints, photograph, the name of his/her employer, his/her address, how long the bearer had been employed, as well as other identification information. Employers often entered a behavioural evaluation, on the conduct of the pass holder. An employer was defined under the law and could only be a <a href="/facts/Whites/DTcnHeMU">white</a> person. The pass also documented permission requested and denied or granted to be in a certain region and the reason for seeking such permission. Under the terms of the law, any government employee could strike out such entries, basically cancelling the permission to remain in the area. A passbook without a valid entry then allowed officials to arrest and imprison the bearer of the pass. These passes often became the most despised symbols of <a href="/facts/Apartheid/8x87W8ex">apartheid</a>. The resistance to the Pass Law led to many thousands of arrests and was the spark that ignited the <a href="/facts/Sharpeville_Massacre/yHW3Fh6L">Sharpeville Massacre</a> on 21 March 1960, and led to the arrest of <a href="/facts/Robert_Sobukwe/5nwRYAPA">Robert Sobukwe</a> that day. </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Border_barrier/eK524beP">Border barrier</a></li> <li><a href="/facts/Airspace/6FbRBRSu">Airspace</a></li> <li><a href="/facts/Air_sovereignty/bfhpS1Cw">Air sovereignty</a></li> <li><a href="/facts/Illegal_entry/4saoBChN">Illegal entry</a></li> <li><a href="/facts/United_States_Border_Patrol/eBGNAtYm">United States Border Patrol</a></li> <li><a href="/facts/Security_guard/hrpVUPqz">Security guard</a></li> <li><a href="/facts/Illegal_immigration/bSFppH6r">Illegal immigration</a></li> <li><a href="/facts/Immigration_law/4LPyQRVH">Immigration law</a></li> <li><a href="/facts/Maritime_boundary/1369gqHz">Maritime boundary</a></li> <li><a href="/facts/Freedom_of_movement/J7c0uovA">Freedom of movement</a></li> <li><a href="/facts/Refugee/VISfRRnT">Refugees</a></li></ul> <h2 id="notes">Notes</h2> <h2 id="further-reading">Further reading</h2> Wikivoyage has a travel guide for <i>Border crossings</i>.
