The Suez Crisis (1956): Causes, Course and Consequences (ISC Class 12 History)
Updated 17 October 2026 · Fact-checked
The Suez Crisis began when Nasser nationalised the Suez Canal Company on 26 July 1956 after the USA and Britain withdrew their offer to finance the Aswan High Dam. Israel invaded Sinai on 29 October, and Britain and France attacked Egypt on the pretext of separating the combatants. Pressure from the USA, USSR and UN forced a ceasefire; Nasser gained prestige while Britain and France were humiliated.
Follow the arrows: Nasser's moves, ending in canal nationalisation, led to war, and outside pressure ended it with Nasser stronger and Britain weaker.

Understand The Suez Crisis (1956): Causes and Results
What the syllabus asks. The syllabus lists the "Suez Crisis (1956)" among the Arab-Israeli conflicts and says "for each of these events, the causes and results should be studied in detail". Give causes, a short course and results.
1. Causes (the policies of all sides).
1. *Nasser's Arab nationalism.* He wanted to free the Arab world from Western influence and supported Palestinian guerrilla (fedayeen) raids into Israel from Gaza.
2. Egypt blockaded the Straits of Tiran, closing the Gulf of Aqaba to Israeli shipping.
3. *The Czech arms deal (1955).* Nasser obtained Soviet-bloc weapons, alarming Israel and the West; Egypt also recognised Communist China.
4. The USA and Britain withdrew their offer to finance the Aswan High Dam (July 1956).
5. Nasser nationalised the Suez Canal Company (26 July 1956) to pay for the dam. Britain and France, the company's main owners, feared for their oil supplies and prestige; France was also angry at Egyptian help to the Algerian rebels.
6. Britain, France and Israel secretly agreed that Israel would attack Egypt, giving Britain and France an excuse to occupy the canal zone.
2. Course. Israel invaded Sinai on 29 October 1956. Britain and France bombed Egypt and landed troops at Port Said on 5-6 November. The USA, the USSR and the UN demanded a ceasefire, and a UN Emergency Force (UNEF) replaced the invaders.
3. Consequences.
1. Humiliation for Britain and France; Prime Minister Anthony Eden resigned (1957); Britain's decline as a world power was exposed.
2. A political triumph for Nasser, who kept the canal and became a hero of Arab nationalism.
3. The canal was blocked by sunken ships until 1957, causing oil shortages and rationing in Europe.
4. The USSR replaced the West as Egypt's backer and financed the Aswan Dam; Soviet influence in the Middle East grew.
5. Israel gained: UNEF troops ended fedayeen raids from Gaza and kept the Gulf of Aqaba open to Israeli shipping.
6. The USA announced the Eisenhower Doctrine (1957) to resist communism in the region.
Note. The secret agreement among Britain, France and Israel (often called the Protocol of Sevres) became known later; at the time the two European powers said they were acting to separate the fighting forces. A balanced answer notes both the official account and the later evidence.

The Suez Crisis (1956): Causes and Results in real life
The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.
Using a resource to fund a plan
Suppose a town council wanted to build a bridge, was refused a loan by the bank, and then took over a profitable toll booth from a private company to raise the money.
Why might the private company's owners be angry, and what could they do?
Try it first, then show the solutionSolution
- They lose a valuable source of income.
- They may argue that the take-over is unfair.
- They may try to reverse it by pressure, even by secret plans.
Answer: Nationalisation of the Suez Canal Company to fund the Aswan Dam provoked its owners, Britain and France, in the same way.
Memory hook: Loan refused, canal taken.
Pressure from bigger powers
Imagine two shopkeepers who join with a third to take back a corner of the market, but the market committee and the biggest suppliers both tell them to stop.
Why do the three stop?
Try it first, then show the solutionSolution
- They depend on the suppliers.
- Losing the committee's support is costly.
- They cannot continue without allies.
Answer: Britain and France stopped because the USA and USSR and the UN opposed them and the pound was under pressure; they lacked the power to act alone.
Memory hook: Powers, not partners.

Try it first, then show the solutionSolution
- Nasser's nationalism and fedayeen (1 mark).
- Tiran blockade and arms deal (2 marks).
- Aswan Dam and nationalisation (2 marks).
- The secret plan (1 mark).
Answer: Nasser's Arab nationalism and support for fedayeen raids from Gaza alarmed Israel, and Egypt blockaded the Straits of Tiran against Israeli shipping. The Czech arms deal of 1955 brought Soviet-bloc weapons to Egypt and alarmed the West. In July 1956 the USA and Britain withdrew their offer to finance the Aswan High Dam, and Nasser responded by nationalising the Suez Canal Company on 26 July. Britain and France, its owners, feared for their oil and prestige and secretly agreed with Israel that Israel would attack Egypt, giving them a pretext to occupy the canal zone.

Try it first, then show the solutionSolution
- Britain and France (2 marks).
- Egypt and Nasser (2 marks).
- Cold War: USSR and USA (2 marks).
Answer: For Britain and France the crisis was a humiliation: Eden resigned in 1957 and British decline as a world power was exposed. For Egypt it was a political triumph: Nasser kept the canal and became a hero of Arab nationalism, though the canal was blocked until 1957, causing oil shortages in Europe. In the Cold War, the USSR replaced the West as Egypt's backer and financed the Aswan Dam, so Soviet influence grew, while the USA announced the Eisenhower Doctrine in 1957 to resist communism in the region.
Example 5: Source-based: an ultimatum · 6 marks · Source-basedHOTS / competency
Read the extract (written for this page) and answer.
In October 1956 an army crossed a desert peninsula towards a canal. Two European governments then announced that, to protect the waterway, they would send their own forces to separate the fighters. A few days later their troops landed at the canal's northern port. The two superpowers, unusually, voted the same way against them, and a UN force arrived.
(i) Name the army and the canal. [1]
(ii) Name the two European governments. [1]

Practice questions on The Suez Crisis (1956): Causes and Results
Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.
Q1 · 2 marks · Very short answerBoard level
What was UNEF and what did it do after the Suez Crisis? [2]
Hint
UN Emergency Force.
Answer
UNEF was the UN Emergency Force. It replaced the invading forces, ended fedayeen raids from Gaza and kept the Gulf of Aqaba open to Israeli shipping.
Q2 · 3 marks · Short answerBoard level
Why did Israel join Britain and France in the attack on Egypt? [3]
Hint
Fedayeen and Tiran.
Answer
Israel wanted to stop fedayeen raids from Gaza and the closure of the Straits of Tiran to its shipping, and was alarmed by Egypt's Czech arms deal. It agreed with Britain and France that it would attack first in Sinai.
Q3 · 4 marks · Short answerHarder board level
Explain why the Aswan High Dam became a cause of the crisis. [4]
Hint
Offer withdrawn, nationalisation.
Answer
Egypt wanted Western finance for the Aswan High Dam, but in July 1956 the USA and Britain withdrew their offer, partly because of the arms deal and Egypt's recognition of Communist China. Nasser responded by nationalising the Suez Canal Company to use its income for the dam, which provoked Britain and France.
Q4 · 5 marks · Short answerHarder board level
Discuss the consequences of the Suez Crisis for Israel and the Arab world. [5]
Hint
Gaza raids ended; Nasser's prestige.
Answer
For Israel, UNEF troops ended the fedayeen raids from Gaza and the Gulf of Aqaba was open to its shipping. For the Arab world, Nasser became a hero of Arab nationalism for keeping the canal, and Soviet backing for Egypt grew. The crisis did not settle the underlying conflict between Israel and its neighbours.
Q5 · 6 marks · Long answerHOTS / competency
"Suez was a military success but a political failure for Britain and France." Evaluate this statement. [6] (Evaluation)
Hint
Compare the battlefield outcome with international reaction.
Answer
Militarily, their forces and Israel's achieved their immediate aims: Israel overran Sinai and the Anglo-French landing at Port Said succeeded. Politically, the result was a failure: the USA, USSR and UN demanded a ceasefire, the canal was blocked, Eden resigned and Nasser kept the canal and gained prestige. The expedition also pushed Egypt closer to the USSR. The statement is therefore largely accurate.
