1 · Understand it

Three documents

Between 1915 and 1917 the British government committed itself three times over the future of Ottoman territory in the Middle East, and the commitments were not compatible.

The first was the Hussein–McMahon correspondence of 1915–16, an exchange of letters between the British High Commissioner in Egypt and Sharif Hussein of Mecca. Britain sought an Arab revolt against the Ottoman Empire, and in exchange indicated support for Arab independence in specified areas. Whether Palestine fell inside or outside the region promised has been argued about ever since, because the letters describe the boundaries by reference to districts whose extent was itself disputed.

The second was the Sykes–Picot agreement of May 1916, a secret understanding between Britain and France dividing the same territory into spheres of influence and control, with Palestine to come under some form of international administration. It was negotiated while the correspondence with Hussein was still being acted on.

The third was the Balfour Declaration of 2 November 1917, a letter from the Foreign Secretary to Lord Rothschild stating that the government viewed with favour the establishment in Palestine of a national home for the Jewish people, and that nothing should be done to prejudice the civil and religious rights of the existing non-Jewish communities there.

Why Britain made them

Each promise had a wartime purpose and none of them was made with the others principally in mind, which is why they overlap.

The correspondence with Hussein was an attempt to open a front against the Ottomans from within, and it produced the Arab Revolt of 1916. Sykes–Picot was an attempt to prevent Britain and France from quarrelling over the spoils while the war was still being fought. The Balfour Declaration had several motives at once: sympathy among some British ministers for the Zionist case argued by Chaim Weizmann and others, a belief that it would win Jewish support in the United States and Russia at a critical moment of the war, and a strategic interest in a friendly presence near the Suez Canal.

The Declaration's own wording repays attention, because both later arguments are contained in it. It promises a national home rather than a state, a phrase deliberately left undefined. It safeguards the civil and religious rights of the existing non-Jewish communities — who were then roughly nine-tenths of the population — but not their political rights, and it names them by what they were not. Every subsequent argument about what Britain undertook can be conducted out of that single sentence.

The mandate and the growth of a population

Britain received the mandate for Palestine from the League of Nations in 1922, with the Balfour Declaration written into its terms. It therefore held a territory in which it was obliged to facilitate a Jewish national home while also administering an Arab majority who had been given to understand that independence was coming.

Immigration turned the abstraction into arithmetic. The Jewish population of Palestine was roughly a tenth of the total after the First World War; by the end of the 1930s it was approaching a third, the increase driven first by movements from Eastern Europe in the 1920s and then, decisively, by flight from Nazi Germany and central Europe after 1933.

That change is the mechanism by which a diplomatic promise became a conflict on the ground. Land purchase, employment practices and the growth of separate institutions made the two communities increasingly distinct, and each new arrival altered the balance in a territory whose political future had been left deliberately undefined by the document that set the process in motion.

2 · Learn it — the notes

The dates that earn marks

1915–16

The Hussein–McMahon correspondence indicates British support for Arab independence in specified areas. Why this date: Whether Palestine was inside the area promised has been disputed ever since, because the boundaries were described ambiguously.

May 1916

The Sykes–Picot agreement secretly divides the region between Britain and France. Why this date: It was negotiated while the promise to Hussein was still being acted on, which is the clearest proof that the commitments were not coordinated.

2 November 1917

The Balfour Declaration favours a national home for the Jewish people in Palestine. Why this date: Its wording — a home rather than a state, civil and religious but not political rights for others — contains both of the arguments that followed.

1922

Britain receives the League of Nations mandate for Palestine, with the Declaration written into its terms. Why this date: It converts a wartime letter into a legal obligation Britain then had to administer for twenty-six years.

The figures, and how far to trust them

• About a tenth rising towards a third — The Jewish share of Palestine's population between the end of the First World War and the late 1930s. (Mandate census and estimate figures differ; the direction and rough scale of the change are not disputed.)
• Two years — The interval within which all three overlapping British commitments were made.
• 1933 — The year after which immigration rose sharply, driven by flight from Nazi Germany and central Europe. (Annual totals fluctuated with British quota policy as well as with conditions in Europe.)

The people to place

• Arthur Balfour — British Foreign Secretary; signed the Declaration of November 1917.
• Chaim Weizmann — Zionist leader in Britain who argued the case that produced the Declaration.
• Mark Sykes — Negotiated the 1916 agreement dividing the region with France.
• Henry McMahon — British High Commissioner in Egypt; conducted the correspondence with Sharif Hussein.

How historians disagree

Attributed interpretations, never voiced — the AO4 seam.

• The 'incompatible promises' reading: Britain made three commitments about the same territory in two years for three separate wartime purposes, and the mandate's conflicts follow from the impossibility of keeping all of them. Contested by The reading that the documents are more compatible than they look — the correspondence may not have covered Palestine, Sykes–Picot was superseded, and the Declaration promised a home within a territory rather than the territory — so the conflict came from what happened afterwards rather than from the promises themselves..

What students say — and what is actually the case

Not this: The Balfour Declaration promised the Jewish people a state in Palestine.

This: It favoured a national home, a phrase deliberately left undefined, and expressly safeguarded the civil and religious rights of the existing non-Jewish communities.

Not this: Britain simply reneged on a promise of Arab independence.

This: Whether the Hussein–McMahon correspondence covered Palestine is genuinely disputed, because the letters define the area by districts whose extent was itself unclear. The dispute is the fact to learn, not either answer.

Two things students merge

Blurred: Civil and religious rights, and political rights.

The distinction: The Declaration safeguards the first for the existing communities and is silent on the second. That silence is where the argument about self-determination begins, and quoting the sentence without noticing it misses the point.

Blurred: A national home and a state.

The distinction: The Declaration's authors chose the vaguer word and later British governments differed on what it meant. Reading 1917 as a promise of statehood imports the outcome of 1948 into the document.

What a Grade 9 answer holds here

A Grade 9 answer reads the Declaration's sentence as carefully as a lawyer would. It promises a home and not a state, it safeguards civil and religious rights and says nothing about political ones, and it identifies nine-tenths of the population only by what they are not — so the whole of the century that followed is already present in sixty-seven words written to serve a wartime purpose.

3 · How it is examined

This strand is genuinely set through: Paper 2 Section B (a) (6 marks — “Explain TWO ways in which … was different from ….”); Paper 2 Section B (b) (8 marks — “Explain TWO causes of ….”); Paper 2 Section B (c)(i) or (c)(ii) (16 marks — “How significant was … in …, in the years …? / How far were … responsible for …, in the years …? You may use the following in your answer: • [prompt] • [prompt]. You must also use information of your own.”).

What earns marks: The two-year window with all three documents named. It converts a general claim about British duplicity into a dated, evidenced sequence.

The cap that bites here: The 6-mark question is capped at 3 marks if only one difference is explained.

4 · Prove it — the questions

Answered inside Incandio, where a marker checks what a correct answer must contain and tells you which half was missing. The marking stays in the app; the questions are here.
