Israel has occupied the Palestinian territories and the Golan Heights of Syria since the Six-Day War of 1967. It has previously occupied the Sinai Peninsula of Egypt and southern Lebanon as well. Prior to 1967, control of the Palestinian territories was split between Egypt and Jordan, which administered the Gaza Strip and the West Bank, respectively. The Israeli occupation of the Palestinian territories and the Golan Heights, where Israel has transferred parts of its population and built large settlements, is the longest military occupation in modern history.
From 1967 to 1981, the four areas were administered under the Israeli Military Governorate, and after the return of the Sinai Peninsula to Egypt after the Egypt–Israel peace treaty, Israel effectively annexed the Golan Heights and East Jerusalem in 1980, and brought the rest of the West Bank and the Gaza Strip under the Israeli Civil Administration.
In 2005, Israel unilaterally disengaged from the Gaza Strip, but the International Court of Justice, the UN General Assembly, and the UN Security Council continue to consider Israel as the occupying power there due to its blockade of the territory.Strongly deplores the continued refusal of Israel, the occupying Power, to comply with the relevant resolutions of the Security Council and the General Assembly; In 2024, the ICJ ruled in an advisory opinion that Israel's occupation was illegal and called for Israel to end its "unlawful presence ... as rapidly as possible" and to make reparations to the people of the occupied territories.
The Supreme Court of Israel has ruled that Israel is holding the West Bank under "belligerent occupation".Beit Sourik Village Council v. The Government of Israel . (PDF) . Retrieved on April 4, 2017.

Between 2023 and 2026, Israel expanded its occupation in the Gaza Strip, Lebanon, and Syria by a combined 1000 square kilometers, as calculated by the Associated Press. In January 2024, following the Hamas attacks on Israel on October 7, Israel reoccupied most of the northern Gaza Strip, leading to further clashes. After a shifting presence of military ground forces during the war, the October 2025 comprehensive agreement established a yellow demarcation line that left the Israeli military in control of 53% of the Gaza Strip. Israel has since shifted this line. In July 2026, NPR reported that Israel's military controlled almost 70% of the strip.
The Israeli military invaded Lebanon during the 2024 war and retained a military presence at five Israeli military outposts in Lebanon afterwards, pledging in April 2025 to remain there. In March and April 2026, Israel began an expanded military occupation within southern Lebanon, reaching a total of 570–608 square kilometers (220–234 sq mi) by the 2026 Israel–Lebanon temporary ceasefire.
In December 2024, Israel occupied the UN buffer zone established to the east of the already occupied Golan Heights in Syria. The United Nations calculates this area at 235 square kilometers (91 square miles).
Background
Before the State of Israel was declared on 14 May 1948, Zionist forces occupied territory in Mandatory Palestine in an offensive called Plan Dalet executed 1 April –14 May of that year. By the end of the 1948 Palestine war, Zionist forces conquered about 78% of the former territory of the mandate, causing the expulsion and flight of over 700,000 Palestinians. The Green Line was established by the 1949 Armistice Agreements.
Overview The significance of the designation of these territories as occupied territory is that certain legal obligations fall on the occupying power under international law. Under international law there are certain laws of war governing military occupation, including the Hague Conventions of 1899 and 1907 and the Fourth Geneva Convention.Occupation and international humanitarian law: questions and answers , International Committee of the Red Cross, 2004. One of those obligations is to maintain the status quo until the signing of a peace treaty, the resolution of specific conditions outlined in a peace treaty, or the formation of a new civilian government.Convention (IV) relative to the Protection of Civilian Persons in Time of War. Geneva, 12 August 1949.Commentary on Part III : Status and treatment of protected persons #Section III : Occupied territories Art. 47 by the ICRC
Israel disputes whether, and if so to what extent, it is an occupying power in relation to the Palestinian territories and as to whether Israeli settlements in these territories are in breach of Israel's obligations as an occupying power and constitute a grave breach of the Geneva Conventions and whether the settlements constitute war crimes.Rome Statute Of The International Criminal Court Article 8 . legal.un.org.

Sinai Peninsula
Israel captured the Sinai Peninsula from Egypt in the 1967 Six-Day War. It established settlements along the Gulf of Aqaba and in the northeast portion, just below the Gaza Strip. It had plans to expand the settlement of Yamit into a city with a population of 200,000,The Arab–Israeli Dilemma (Contemporary Issues in the Middle East), Syracuse University Press; 3rd edition (August, 1985) though the actual population of Yamit did not exceed 3,000.Kintera.org—The Giving Communities . Theisraelproject.org. Retrieved on 2012-01-15. The Sinai Peninsula was returned to Egypt in stages beginning in 1979 as part of the Egypt–Israel peace treaty. As required by the treaty, Israel evacuated Israeli military installations and civilian settlements before the establishment of "normal and friendly relations" between it and Egypt."Upon completion of the interim withdrawal provided for in Annex I, the parties will establish normal and friendly relations, in accordance with Article III (3)." Israel dismantled eighteen settlements, two air force bases, a naval base, and other installations by 1982, including the only oil resources under Israeli control. The evacuation of the civilian population, which took place in 1982, was done forcefully in some instances, such as the evacuation of Yamit. The settlements were demolished, as it was feared that settlers might try to return to their homes after the evacuation. Since 1982, the Sinai Peninsula has not been regarded as occupied territory.
South Lebanon
The Israeli occupation of southern Lebanon took place after Israel invaded Lebanon during the 1982 Lebanon War and subsequently retained its forces to support the Christian South Lebanon Army militia in Southern Lebanon. In 1982, the Israel Defense Forces (IDF) and allied Free Lebanon Army Christian militias seized large sections of Lebanon, including the capital of Beirut, amid the hostilities of the wider Lebanese Civil War. Later, Israel withdrew from parts of the occupied area between 1983 and 1985, but remained in partial control of the border region known as the South Lebanon Security Belt, initially in coordination with the self-proclaimed Free Lebanon State, which executed a limited authority over portions of southern Lebanon until 1984, and later with the South Lebanon security belt administration and its South Lebanon Army (transformed from Free Lebanon Army), until the year 2000. Israel's stated purpose for the Security Belt was to create a space separating its northern border towns from terrorists residing in Lebanon.
During the stay in the security belt, the IDF held many positions and supported the SLA. The SLA took over daily life in the security zone, initially as the official force of the Free Lebanon State and later as an allied militia. Notably, the South Lebanon Army controlled the prison in Khiam. In addition, United Nations (UN) forces and the United Nations Interim Force in Lebanon (UNIFIL) were deployed to the security belt (from the end of Operation Litani in 1978).
The strip was a few kilometers wide, and consisted of about 10% of the total territory of Lebanon, which housed about 150,000 people who lived in 67 villages and towns made up of Shiites, Maronites, and Druze (most of whom lived in the town of Hasbaya). In the central zone of the Strip was the Maronite town Marjayoun, which was the capital of the security belt. Residents remaining in the security zone had many contacts with Israel, many of whom have worked there and received various services from Israel.
Before the Israeli election in May 1999, the Prime Minister of Israel, Ehud Barak, promised that within a year all Israeli forces would withdraw from Lebanon. When negotiation efforts failed between Israel and Syria—the goal of the negotiations was to bring a peace agreement between Israel and Lebanon as well, due to Syrian occupation of Lebanon until 2005—Barak led the withdrawal of the IDF to the Israeli border on 24 May 2000. No soldiers were killed or wounded during the redeployment to the internationally recognized border of Blue Line.
Israel occupied parts of Lebanon again during the 2006 Lebanon War until the 1 October 2006 and has since began an ongoing occupation of parts of southern Lebanon during the 2024 Israeli invasion of Lebanon, and during the 2026 Lebanon war.
Golan Heights
Israel captured the Golan Heights from Syria in the 1967 Six-Day War. A ceasefire was signed on 11 June 1967 and the Golan Heights came under Israeli military administration.During the Autumn of 2003, following the declassification of key Aman documents , the newspaper Yedioth Ahronoth released a series of controversial articles which revealed that key Israeli figures were aware of considerable danger that an attack was likely, including Golda Meir and Moshe Dayan, but had decided not to act. The two journalists leading the investigation, Ronen Bergman and Gil Meltzer, later went on to publish Yom Kippur War, Real Time: The Updated Edition, Yediot Ahronoth/Hemed Books , 2004. Syria rejected UNSC Resolution 242 of 22 November 1967, which called for the return of Israeli-occupied State territories in exchange for peaceful relations. Israel had accepted Resolution 242 in a speech to the Security Council on 1 May 1968. In March 1972, Syria "conditionally" accepted Resolution 242, and in May 1974, the Agreement on Disengagement between Israel and Syria was signed.
