Key topic 3 · The defeat of Austria, 1854–59

What a Grade 9 answer knows here. Villafranca is the test of whether Cavour was a nationalist or a Piedmontese statesman: France stopped the war halfway and Piedmont still took Lombardy, then paid for it in Nice and Savoy — territory traded for territory, which is not how a national movement behaves.

The 3 lessons

The significance of the Crimean War

What did Piedmont buy with two thousand dead in a war it had no quarrel in? Piedmont had tried twice, in 1848 and 1849, to expel Austria from northern Italy by its own strength and had been beaten both times.

Orsini, Plombières and the Second War of Independence

How did an attempt to assassinate Napoleon III end in a French alliance with Italian nationalism? On 14 January 1858 Felice Orsini, an Italian nationalist, threw bombs at Napoleon III's carriage outside the Paris opera.

Magenta, Solferino, Villafranca and the annexations

What does it tell us about Cavour that Piedmont accepted Lombardy and paid for it in Nice and Savoy? The Franco-Piedmontese forces won at Magenta on 4 June 1859 and entered Milan; on 24 June they won again at Solferino, a battle so costly that a Swiss observer, Henri Dunant, went home and founded what became the Red Cross.

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.

January 1855 — Piedmont allies with Britain and France and sends troops to the Crimea.: It is a decision to spend lives on standing rather than on territory, which is the clearest example of Cavour's method. (The significance of the Crimean War)
August 1855 — Piedmontese troops fight at the Chernaya.: It supplies the creditable record on which the claim to be treated as an ally rests. (The significance of the Crimean War)
January 1858 — Orsini's bomb attack on Napoleon III.: It convinced the Emperor that an unsettled Italy was a danger to him personally, and the publication of Orsini's letter shows how he chose to use it. (Orsini, Plombières and the Second War of Independence)
July 1858 — The secret meeting at Plombières.: It sets the terms — a four-state federation, Nice and Savoy to France — that are the strongest evidence about Cavour's actual aims. (Orsini, Plombières and the Second War of Independence)
June 1859 — Magenta and Solferino; about forty thousand casualties in a day at Solferino.: The cost is a large part of why Napoleon III stopped, so the battles explain the peace as well as the victory. (Magenta, Solferino, Villafranca and the annexations)
July 1859 — The Treaty of Villafranca; Cavour resigns.: France makes peace without its ally, keeping Venetia in Austrian hands and ordering the restoration of the central rulers. (Magenta, Solferino, Villafranca and the annexations)

The people to place

Cavour — Argued for the intervention against domestic scepticism and attended the Congress of Paris. (The significance of the Crimean War)
Alfonso La Marmora — Commanded the Piedmontese force in the Crimea. (The significance of the Crimean War)
Napoleon III — French Emperor; the audience the whole intervention was aimed at. (The significance of the Crimean War)
Felice Orsini — Italian nationalist whose attempt on Napoleon III, and letter from prison, reopened the Italian question in France. (Orsini, Plombières and the Second War of Independence)
Victor Emmanuel II — Accepted the Villafranca terms against his minister's advice. (Magenta, Solferino, Villafranca and the annexations)

What students say — and what is actually the case

“Piedmont gained territory or promises at the Congress of Paris.” — It gained nothing concrete at all. The value was a hearing and a set of private conversations, which is why the significance is genuinely arguable. (The significance of the Crimean War)
“Plombières was an agreement to unify Italy.” — It provided for four Italian states in a confederation presided over by the Pope, with Nice and Savoy ceded to France. Nothing in it unifies anything. (Orsini, Plombières and the Second War of Independence)
“Piedmont gained Venetia in 1859.” — Villafranca left Venetia with Austria. It was obtained in 1866 as a result of Prussia's victory, and the seven-year gap is examinable. (Magenta, Solferino, Villafranca and the annexations)
