Exam scope and assessment notes
This original lesson maps Cambridge IGCSE History 0977 key question A2 for exams in 2024–2030. 0470 uses grades A*–G; 0977 uses grades 9–1 and has limited zone availability. Cambridge states that the 2029–2030 syllabus has no significant changes affecting teaching and that resources for examinations from 2024 remain suitable. This pathway maps the shared subject content across the published 2024–2030 cycles; always use the exact exam-year syllabus, exam-series prescribed topic and centre route. Cambridge 0977 is offered only in specified administrative zones and locations; confirm that your centre can enter this grading route and exam series. StudyForA explanations, examples and practice are original learning materials, not Cambridge questions, source documents, mark schemes or grades. Paper 2's prescribed topic changes each exam series: use the exact topic for your year and series from Cambridge. Source-analysis exercises here use clearly labelled, invented practice claims and do not reproduce historical documents. Component 3 is centre-approved coursework based on a depth study and needs authentic learner work, supervision, internal assessment and Cambridge moderation; StudyForA cannot conduct, authenticate or award that coursework mark. Practice feedback is formative and is not an official Cambridge grade.
Before you begin
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
How should you approach this question: How was Italy unified?
What you will learn
- Explain Austrian influence, Mazzini's nationalism and why the 1848–49 revolutions did not unify Italy.
- Compare Cavour's diplomacy and war, Victor Emmanuel II's monarchy and Garibaldi's campaign in Sicily and Naples.
- Sequence the creation of the Kingdom of Italy and later acquisition of Venetia and Rome, judging the contribution of different forces.
Different routes to a nation
Italy was divided into states and Austrian influence constrained change. Mazzini promoted a united republic and helped inspire nationalist movements, but the 1848–49 revolutions were defeated.
Piedmont-Sardinia offered a monarchy-led alternative. Cavour used diplomacy and the agreement at Plombières to secure French support before war with Austria in 1859; victory enabled much of northern Italy to join the new state.
Unification through campaign and settlement
Garibaldi's volunteers invaded Sicily and Naples in 1860. He handed control to Victor Emmanuel II rather than insisting on a rival republic; the Kingdom of Italy was proclaimed in 1861.
Venetia joined after the 1866 conflict involving Austria, while Rome became part of the kingdom in 1870 when French protection ended. Unification was therefore a sequence, not one battle, and the new state still faced regional and political divisions.

Pause and explain
Why is 1861 an incomplete date for Italian unification?
Worked example
Was Italian unification mainly achieved by popular nationalism?
Show the worked solution
- Recognise that national feeling helped create pressure and volunteers.
- Compare this with Cavour's diplomacy and the Piedmontese army and monarchy.
- Conclude by distinguishing the stages and noting the limits of unity after 1870.
Answer Popular nationalism helped make unification possible, especially through Mazzini's ideas and Garibaldi's campaign. But Cavour's diplomacy, Piedmont-Sardinia's military strength and Victor Emmanuel II's acceptance of a united kingdom were also decisive. No single actor explains the whole process.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Explain how Cavour and Garibaldi contributed differently to unification.
Give me a hint
Start with one named syllabus fact, explain its effect and connect it to the question.
Compare my reasoning
- Select accurate evidence: Cavour secured French support while Garibaldi's campaign brought the south into a kingdom.
- Explain the link between that fact and the issue being tested.
- Add a second condition or limitation before reaching a short answer. A model answer follows: Cavour worked through Piedmont-Sardinia's government, diplomacy and war, including French support against Austria in 1859. Garibaldi used a volunteer campaign in the south, capturing Sicily and Naples and then accepting Victor Emmanuel II as monarch. Their methods differed but helped create one kingdom.

Look for these in your work
- Uses a relevant named fact
- Explains a cause, consequence or comparison
- Qualifies the conclusion with evidence
How far was Cavour responsible for Italian unification?
Give me a hint
Choose a clear criterion for importance or success; compare evidence before you decide.
Compare my reasoning
- Select accurate evidence: Cavour secured French support while Garibaldi's campaign brought the south into a kingdom.
- Compare the strongest supporting evidence with a counterpoint.
- State which factor matters most, for whom and during which period. A model answer follows: Cavour was central because diplomacy and Piedmontese power made northern expansion possible. However, popular nationalism and Garibaldi's campaign transformed the south, and later events added Venetia and Rome. Cavour was a leading architect, but unification depended on several actors and stages.

Look for these in your work
- Selects evidence from the correct period
- Weighs more than one factor
- Makes a supported judgement
Original StudyForA practice claim (not a historical source): ‘Italy was unified in a single popular uprising.’ Evaluate the claim.
Give me a hint
Treat the prompt as an interpretation to test. Identify what evidence supports it and what it leaves out.
Compare my reasoning
- Select accurate evidence: Cavour secured French support while Garibaldi's campaign brought the south into a kingdom.
- Check the claim against at least two relevant pieces of contextual knowledge.
- Explain a limitation or alternative explanation; do not treat an invented practice prompt as a real historical source. A model answer follows: Popular movements mattered, but the claim overlooks the monarchy, diplomacy, foreign alliances and the sequence from 1859 through 1870. The Kingdom was proclaimed in 1861; Venetia and Rome joined later. A sound account combines popular action with state strategy and chronology.

Look for these in your work
- Tests rather than repeats the claim
- Uses contextual knowledge to support or challenge it
- Explains a limitation and reaches a qualified conclusion
Common mistakes
- Treating Mazzini, Cavour and Garibaldi as pursuing the same political model
- Saying unification was complete in 1861
- Ignoring foreign intervention and the continuing regional divisions

Make it stick
Without looking, state the key question, name two syllabus facts that bear on it, and explain one limit to your first conclusion.
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
