What this dot point is asking
The CCEA A2 2 Historical Investigations and Interpretations paper tests the historian's craft: you work with primary sources and historians' interpretations of a controversy and must analyse and evaluate them, supported by an outline essay. The partition of Ireland 1900 to 1925 is one of the option's classic controversies. You need a secure grasp of the events, but the marks (AO3) come from evaluating how historians have interpreted the causes of and responsibility for partition, tested against your own knowledge, not from narrating the period.
The road to partition 1900 to 1925
- The Ulster crisis (1912 to 1914). The Third Home Rule Bill, no longer permanently blockable after the Parliament Act of 1911, provoked unionist resistance: the Solemn League and Covenant of September 1912 and the armed Ulster Volunteer Force of 1913. Coercing concentrated unionist majorities in the north-east into a Dublin parliament became politically impossible.
- War and rebellion. The First World War suspended Home Rule in 1914. The Easter Rising of 1916 and the execution of its leaders swung opinion towards republican separatism, and Sinn Fein swept the 1918 election.
- Legislation and settlement. The Government of Ireland Act of 1920 created two Home Rule parliaments, putting partition on the statute book. The Anglo-Irish Treaty of December 1921 created the Free State as a dominion and let Northern Ireland opt out, which it immediately did. The Boundary Commission was meant to revise the border but collapsed in 1925, fixing the existing six-county line.
The historiographical debate
These interpretations rest on different emphases. A historian who stresses unionist agency points to the Covenant, the Ulster Volunteer Force and the Larne gun-running as proof that the north-east would resist incorporation by force. A historian who stresses British responsibility points to the 1920 Act and the Treaty as the decisive instruments that translated resistance into a border. A historian who stresses two-traditions division reads partition as the constitutional recognition of a religious and political fracture that long predated 1920. The differences arise from which evidence is foregrounded and what each historian takes to be the underlying cause.
Examples in context
A model evaluative paragraph might read: "Interpretation A is persuasive in locating the root of partition in the strength of Ulster unionism, but it overstates the inevitability of the outcome. It is right that the resistance of 1912 to 1914 was formidable: the Solemn League and Covenant, signed by close to half a million people, and the armed Ulster Volunteer Force made the coercion of the north-east into a Dublin parliament a practical impossibility, and any explanation that ignored this would be incomplete. Yet the interpretation underplays the decisive role of British policy that Interpretation B captures, for it was the Government of Ireland Act of 1920, a Westminster measure, that actually drew the line and created two parliaments, and it was the Treaty of 1921 that allowed Northern Ireland to opt out in its specific six-county shape. Tested against the evidence, unionist strength explains why some separation was likely, while British legislation explains the form, timing and boundary it took. The most convincing judgement therefore synthesises the two interpretations rather than choosing between them." Every sentence evaluates the interpretation against evidence rather than narrating the period.
Try this
Q1. Which Act of Parliament put partition on the statute book? [2 marks]
- Cue. The Government of Ireland Act of 1920, which created two Home Rule parliaments and separated the six north-eastern counties.
Q2. Give three different interpretations historians offer of responsibility for partition. [3 marks]
- Cue. That Ulster unionist strength made it unavoidable, that British policy and the 1920 Act brought it about, and that a long-standing division between two communities and traditions underlay it.
Q3. Using sources and interpretations, assess the view that Ulster unionism was the main reason for the partition of Ireland. [20 marks]
- Cue. Identify what the interpretations argue, explain why historians differ, test the view that unionism was decisive against British policy and Irish division using precise evidence, and reach a substantiated judgement rather than narrating events.

CCEA A2 201920 marksUsing these sources and interpretations, assess the view that Ulster unionism was the main reason for the partition of Ireland.Show worked answer →
The A2 2 document question is assessed mainly on AO3 (analysing and
evaluating sources and interpretations), supported by AO1 knowledge. Engage
with the interpretations, do not narrate the period.
Identify the views. State what the given sources and interpretations argue
about responsibility for partition, distinguishing those that stress Ulster
unionist strength from those that stress British policy or nationalist
division.
Cross-reference. Show where the material agrees and disagrees, and explain
why historians differ (different evidence, emphasis or assumptions).
Test against knowledge. Use precise evidence (the Solemn League and Covenant,
the Ulster Volunteer Force, the Government of Ireland Act of 1920, the Treaty
of 1921) to weigh the view that unionism was decisive against alternatives.
Judgement. Reach a substantiated verdict on how convincing the view is. Top-
band answers sustain evaluation of the interpretations throughout rather
than describing the events.
CCEA A2 202220 marksHow convincing is the interpretation that British policy, rather than Irish division, brought about partition?Show worked answer →
A focused AO3 evaluation of one interpretation, weighed against an
alternative and your own knowledge.
State the claim. Explain precisely what the interpretation argues about
British responsibility for partition.
Support. Marshal evidence that fits: British unwillingness to coerce Ulster,
the partitionist Government of Ireland Act of 1920, and the Treaty terms of
1921 that let Northern Ireland opt out.
Qualify. Set this against evidence that internal Irish division mattered: the
depth of Ulster unionist resistance and the split between nationalism and
unionism that long predated 1920.
Judgement. Decide how convincing the interpretation is, conceding the force
of the alternative. Sustained evaluation, not narrative, reaches the top
band.
