Algeria–Libya border

France occupied much of the northern coastal areas of Algeria in the period 1830–47, which had hitherto been subject to the nominal control of the Ottoman Empire.{{Cite book|title=African Boundaries: A Legal and Diplomatic Encyclopedia|last=Brownlie|first=Ian|author-link=Ian Brownlie|publisher=Institute for International Affairs, Hurst and Co.|year=1979|pages= 26–43 }} For most of the 19th century the coastal region of modern Libya (organised as the Vilayet of Tripolitania) was part of the Ottoman Empire, though with a large degree of de facto autonomy.{{citation |url= https://fall.fsulawrc.com/collection/LimitsinSeas/IBS001.pdf|title=International Boundary Study No. 1 – Algeria-Libya Boundary|date=28 April 1961|access-date=27 January 2020}} In September 1911 Italy invaded Tripolitania, and the Treaty of Ouchy was signed the following year by which the Ottomans formally ceded sovereignty of the area over to Italy.[https://www.jstor.org/stable/2212446 Treaty of Peace Between Italy and Turkey] The American Journal of International Law, Vol. 7, No. 1, Supplement: Official Documents (Jan., 1913), pp. 58–62 {{doi|10.2307/2212446}}{{cite web | title=Treaty of Lausanne, October, 1912 | url=http://www.mtholyoke.edu/acad/intrel/boshtml/bos142.htm | publisher=Mount Holyoke College, Program in International Relations | access-date=2020-01-27 | archive-date=2013-09-01 | archive-url=https://web.archive.org/web/20130901200924/https://www.mtholyoke.edu/acad/intrel/boshtml/bos142.htm | url-status=dead }} The Italians organised the newly conquered regions into the colonies of Italian Cyrenaica and Italian Tripolitania and gradually began pushing further south; in 1934 they united the two territories as Italian Libya.{{cite web|url=http://www.historyworld.net/wrldhis/PlainTextHistories.asp?historyid=aa83|title=HISTORY OF LIBYA|publisher=HistoryWorld}}

France and Italy signed a treaty on 12 September 1919 which delimited a boundary between Algeria and Libya. During the North African Campaign of the Second World War Italy was defeated and its African colonies were occupied by the Allied powers, with Libya split into British and French zones of occupation. Libya was later granted full independence on 2 December 1951.

France, which had long been dissatisfied with aspects of the border, signed a treaty with Libya in 1955-6 which altered part of the border between Ghadames and Ghat, thereby enabling more effective administration. Following a war Algeria gained independence in 1962, and the border became one between two sovereign states.

Relations since independence have largely been cordial, though the border remains generally insecure due to the impact of terrorism and spill-over from the Libyan Civil War.{{cite news|url=http://www.middleeasteye.net/columns/truth-and-algerian-involvement-libya-1979161660 |title=Truth and Algerian involvement in Libya |publisher=Middle East Eye |date=7 July 2014 |access-date=31 July 2014 |author=Keenan, Jeremy |archive-date=23 July 2014 |archive-url=https://web.archive.org/web/20140723030325/http://www.middleeasteye.net/columns/truth-and-algerian-involvement-libya-1979161660 |url-status=live}}{{cite web|url=http://www.al-monitor.com/pulse/originals/2014/05/algeria-terrorism-egypt-alliance-libya.html |title=Algeria considers Egypt alliance to confront Libyan terror threat |publisher=Al-Monitor |date=21 May 2014 |access-date=31 July 2014 |author=Shabbi, Omar |archive-url=https://web.archive.org/web/20140808051807/http://www.al-monitor.com/pulse/originals/2014/05/algeria-terrorism-egypt-alliance-libya.html |url-status=live |archive-date= 8 August 2014}}
