See it on the Battles & Wars map →What happened
Tensions rose in May 1967 as Egypt's Gamal Abdel Nasser expelled UN peacekeepers from Sinai, massed troops and closed the Straits of Tiran to Israeli shipping. On June 5 Israel struck first, destroying most of Egypt's air force on the ground within hours. In six days Israel took the Sinai Peninsula and Gaza Strip from Egypt, the West Bank and East Jerusalem from Jordan, and the Golan Heights from Syria. Israel lost under 1,000 dead; Arab losses were many times higher.
Why it matters
It more than tripled the land under Israeli control, began Israel's rule over the West Bank and Gaza, still at the heart of the conflict, and produced UN Resolution 242's 'land for peace' formula.
How we know
Israeli, Arab, US and Soviet archives, UN records, battlefield accounts and the text of UN Security Council Resolution 242 (November 1967).
Still debated
Whether Israel's first strike was preemption against a real threat or a war of choice, and whether Nasser actually meant to attack, is debated.
Connections (3)
▸Six-Day War was a decisive round of Arab–Israeli warsWell documented
The connection
Israel's quick victory transformed the conflict. Capturing Sinai, Gaza, the West Bank, East Jerusalem and the Golan Heights shifted the dispute partly from Israel's existence toward these territories. Arab leaders at Khartoum answered with 'no peace, no recognition, no negotiation', while UN Resolution 242 proposed land for peace.
When and how
Middle East, June 1967; the Arab League summit at Khartoum, August–September 1967; UN Resolution 242, November 22, 1967.
How we know
UN resolutions and the Khartoum declaration document the shift; the territorial changes are fully recorded.
Debates and open questions
Israelis and Palestinians dispute the status of the captured land, including settlements and Jerusalem; readings of Resolution 242's wording still differ.
▸Six-Day War led to Yom Kippur War (October War)Well documented
The connection
Egypt and Syria wanted back the Sinai and Golan Heights lost in 1967. A grinding 'War of Attrition' along the Suez Canal (1967–70) and failed diplomacy convinced Egypt's Anwar Sadat that a limited war was needed to force negotiations. Israel's confidence after 1967 led it to underestimate the threat.
When and how
Suez Canal and Golan Heights, 1967–1973; Sadat and Syria's Hafez al-Assad planned the joint attack in 1973.
How we know
Sadat's own statements and Egyptian planning documents state the aim; Israel's Agranat Commission criticized pre-war overconfidence.
Debates and open questions
Whether Israel or the US missed real chances for a deal before 1973, such as Sadat's 1971 peace overtures, is debated.
▸Six-Day War began Israel's control over Gaza, a root of Israel–Hamas warWell documented
The connection
In 1967 Israel captured the Gaza Strip from Egypt, beginning decades of Israeli rule over Gaza's Palestinians, many of them refugees from 1948. Hamas was founded there in 1987 at the start of the First Intifada, an uprising against that rule. Israel withdrew its settlers in 2005 but, with Egypt, blockaded Gaza after Hamas took power in 2007.
When and how
Gaza, June 1967; Hamas founded December 1987; Israel's 'disengagement' in 2005; Hamas seized Gaza from its rival Fatah in June 2007, after which the blockade began.
How we know
The sequence is well documented in UN records, Israeli and Palestinian sources, and Hamas's own 1988 charter, which frames its struggle against Israel.
Debates and open questions
Each side tells it differently: Israel stresses Hamas's aim of destroying it, Palestinians stress occupation and blockade. How much each drove October 7 is contested.
