WHY DID BRITAIN ENTER WORLD WAR I? SOURCE READING SHEET Selected British parliamentary records; public arguments and quoted communications are not a complete private cabinet archive. Treaty text below is represented by translated extracts, not the full treaty. TIMELINE 19 April 1839 | Treaty framework | The treaty and annex placed Belgian independence and neutrality under the named powers’ guarantee. | D4, Article I and Annex VII; extracts printed in 1914, not the complete treaty. 22 November 1912 | Consultation, not an automatic war promise | The letter Grey read to the Commons said expert consultations did not restrict either government’s freedom to decide about armed assistance. | D1, columns 1813–14; this is the document as presented in Grey’s address. 2 August 1914 | A conditional naval assurance | Grey told the Commons on 3 August that he had given the French ambassador an assurance “yesterday afternoon” about protection against specified German naval action. | D1, columns 1817–18; subject to parliamentary support and the stated contingency. 3 August 1914 | The parliamentary case | Grey discussed France, British interests and Belgian neutrality while explicitly saying his information about the Belgian ultimatum was not yet complete. | D1, columns 1809–27; an argument for policy, not a declaration that war had already begun for Britain. 4 August 1914 | Violation reported and an assurance demanded | Asquith relayed the report of German entry at Gemmenich, rejected Germany’s assurance against annexation as insufficient, and demanded a satisfactory reply about neutrality. | D2, columns 1925–27; German explanations appear as communications quoted by the British government. 11 p.m., 4 August 1914 | State of war | Asquith said on the following day that a state of war had existed since eleven o’clock the previous night. | D3, column 1963; distinguish the date of the event from the date of the statement. 5 August 1914 | Confirmation and publication | Asquith confirmed the state of war and relayed Belgium’s appeal; Acland supplied the translated treaty extracts in a written answer. | D3 and D4; publication explains the government’s case, not every private decision leading to it.

What exactly was guaranteed? In D4, which passage puts the annexed provisions under a guarantee, and which passage describes Belgium as neutral? Why should these two jobs be distinguished? Passage, date and source: ______ Answer and evidence limit: ______ 2. What changed between 1912 and 2 August? Use D1 to compare the 22 November 1912 letter with the naval assurance given “yesterday afternoon.” Does the first document already promise automatic British entry into any French war? Passage, date and source: ______ Answer and evidence limit: ______ 3. Was the Belgian information equally complete on both days? Compare Grey’s comments on 3 August in D1 with Asquith’s statement on 4 August in D2. Identify the difference between a reported ultimatum and a reported border violation. Passage, date and source: ______ Answer and evidence limit: ______ 4. Why was no annexation not enough? D2 quotes Germany’s assurance that Belgian territory would not be annexed. Why did the British government reject that assurance as an adequate answer about neutrality? Passage, date and source: ______ Answer and evidence limit: ______ 5. Did Britain enter the war on 5 August? D3 is dated 5 August. Asquith says a state of war existed “since eleven o’clock last night.” What event date should you write, and what should remain dated 5 August? Passage, date and source: ______ Answer and evidence limit: ______ 6. Was the Commons unanimous? In D1, compare Bonar Law’s response with Ramsay MacDonald’s. Does the record justify saying that everyone supported Grey or that the speech was a unanimous formal vote for war? Passage, date and source: ______ Answer and evidence limit: ______ ANSWER KEY 1. Article I supplies the guarantee wording; Article VII of the annex describes Belgian independence and perpetual neutrality. The translated extracts perform different jobs. Article I says the annexed articles have the same force and validity as if inserted in the act and places them under the named monarchs’ guarantee. Annex VII specifies Belgium’s independent, perpetually neutral status and its duty to observe neutrality toward other states. Identifying those clauses shows what the published text says. It does not establish one uncontested legal procedure requiring every guarantor to take an identical military action. Grey’s discussion of the 1870 precedent in D1 shows that the scope and circumstances of action were themselves discussed. 2. No. The letter preserved freedom to decide. The later assurance was a specific conditional commitment about German naval action against French coasts or shipping. Grey read the 1912 letter to explain that military and naval consultations were not themselves binding engagements to assist by force. He then described a newer assurance, given on 2 August, under specified circumstances and subject to parliamentary support. These are not interchangeable pieces of evidence. Saying there was no automatic alliance does not mean there were no preparations, expectations or later commitments. Conversely, the later naval assurance was not an announcement that an expeditionary army had already been promised: Grey explicitly separated that question in the same address. 3. Grey described incomplete information about the ultimatum. Asquith subsequently quoted a report that German forces had entered Belgian territory at Gemmenich. The source dates matter. Grey said he did not yet have complete and definite information on the ultimatum when addressing the House. On 4 August, Asquith presented the Belgian legation’s report that territory had been violated, followed by information of a further advance. Reading the later report back into every sentence of the earlier speech erases an important change in the government’s information. Both reports reach the reader through British parliamentary statements; checking their provenance is different from assuming that the historian has independently inspected every original incoming telegram. 4. Not annexing territory after the war did not mean respecting neutrality while moving an army through it. The quoted German message acknowledged that neutrality had to be disregarded and justified that course by alleged French danger. Asquith said the communication was not satisfactory and repeated the request for an assurance about neutrality. In this record, territorial annexation, military passage, present neutrality and future independence are distinct questions. The message’s assertion about French plans is a German claim quoted by the British government, not a fact this worksheet independently establishes. A guarantee about one issue therefore cannot be silently treated as an answer to all the others. 5. Write 4 August 1914 for the state of war beginning at eleven o’clock that night. Date the parliamentary confirmation 5 August. The statement describes an event on the preceding evening. It does not move the beginning of the state of war to the day on which the House heard the report. This distinction is useful whenever a source was written after what it describes. D2’s request for a reply “before midnight” and D3’s retrospective statement should be quoted with their own context; the selected records here do not by themselves print a time-zone explanation for the deadline. This guide does not convert that phrase into a separately verified deadline for another city. 6. No. Bonar Law offered opposition-party support; MacDonald opposed the policy. The Speaker also stated that no motion was before the House at that point. MacDonald argued that Grey had not persuaded him that Britain was in danger and questioned entry into a wider European war. He expressed conditional support for a conflict confined to protecting Belgium, while rejecting the policy as presented. Those qualifications matter: the speech is not simply indifference to Belgium. Bonar Law’s support and MacDonald’s dissent demonstrate different positions in this debate, but neither speech measures all public opinion or every party member’s view. The Speaker’s procedural statement prevents treating the exchange as a recorded unanimous war-resolution vote.
