Key topic 5 · Venice and Rome and the extent of unification by 1870

What a Grade 9 answer knows here. Italy acquired both Venetia and Rome by being on the right side of somebody else's war, and lost the battles it fought for them. That is the argument for foreign policy over national feeling as the driver — and the reason 'Piedmontisation' left the south with a state it experienced as occupation.

The 3 lessons

Obstacles to unity after 1861 and 'Piedmontisation'

Why did the new kingdom use more troops against its own southern citizens than it had used against Austria? The plebiscites had annexed the other Italian states to the Kingdom of Sardinia rather than creating a new constitutional settlement.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

1861 — Piedmontese law, tariffs, currency and conscription are extended to the whole kingdom.: It converts annexation into administration, and it is the specific mechanism by which unification was experienced in the south. (Obstacles to unity after 1861 and 'Piedmontisation')
1861–65 — The brigands' war in the southern provinces.: More troops were deployed against it than in any war of unification, which measures how far the new state was accepted. (Obstacles to unity after 1861 and 'Piedmontisation')
1862 — Garibaldi is stopped and wounded by the Italian army at Aspromonte.: The state shoots the national hero to avoid war with France, which shows exactly where the constraint on Italian policy lay. (Venetia and Rome: acquired through other people's wars)
1866 — Italy is defeated at Custoza and Lissa and receives Venetia after Prussia's victory.: It is the clearest case of a province acquired by another power's success. (Venetia and Rome: acquired through other people's wars)
1871 — Rome becomes the capital; Pius IX rejects the Law of Guarantees.: The territorial settlement is completed and the religious one is refused in the same year, which is the shape of the whole problem. (Unity in 1870: what had and had not been achieved)
1871 — The franchise stands at about two per cent of the population.: It measures how far the state that had been unified was in any sense representative of the people unified into it. (Unity in 1870: what had and had not been achieved)

The people to place

Victor Emmanuel II — King of Italy from 1861; the state was his existing kingdom enlarged rather than a new creation. (Obstacles to unity after 1861 and 'Piedmontisation')
Pius IX — Refused to recognise the kingdom and eventually forbade Catholic participation in its politics. (Obstacles to unity after 1861 and 'Piedmontisation')
Otto von Bismarck — Prussian minister-president; the alliance of 1866 delivered Venetia to Italy through Prussian victory. (Venetia and Rome: acquired through other people's wars)
Giuseppe Garibaldi — Attempted Rome in 1862 and 1867 and was stopped by the Italian army and then by the French. (Venetia and Rome: acquired through other people's wars)
Massimo d'Azeglio — Piedmontese statesman associated with the observation that Italians still had to be made. (Unity in 1870: what had and had not been achieved)

What students say — and what is actually the case

“Unification was welcomed everywhere in Italy.” — The southern provinces required four years of military repression, and the plebiscites that preceded it were open and administered. Enthusiasm existed and was concentrated among the educated and propertied. (Obstacles to unity after 1861 and 'Piedmontisation')
“Italy won Venetia by defeating Austria in 1866.” — Italy was beaten at Custoza and at Lissa. Venetia was ceded because Prussia destroyed the Austrian army at Sadowa, and it was transferred through France. (Venetia and Rome: acquired through other people's wars)
“Unification created a united Italian people.” — It created a state. Most of its inhabitants did not speak the national language, could not vote, and in many cases were instructed by their church not to participate. (Unity in 1870: what had and had not been achieved)

Then teach it, and defend it

Every lesson above ends the same way: you explain the argument to Ember, an AI pupil who asks the awkward question, and defend it in a structured debate marked against published descriptors.
