Development of a nation: unification of Italy, 1848–70 · Option 2 · Paper 1 — depth study

Key topic 4 · Garibaldi and the Papal States

What a Grade 9 answer knows here. Cavour's decisive act in 1860 was to invade the Papal States in order to get to Garibaldi first. Unification's most famous partnership was in fact a race, and the annexation plebiscites were held to make a conquest look like a choice.

Every lesson here ends the same way: learn it, teach it to an AI pupil who asks the awkward question, then defend it against the thinker with the strongest claim on it — free · no account needed.

2 lessons, each answering one essential question with the story, the dates that earn marks, the people to place, how historians disagree and the cap in the mark scheme that bites. Completely free.

The 2 lessons

Garibaldi's expedition to Sicily and Naples

How did a thousand volunteers take a kingdom of nine million, and why did Turin neither help nor stop them? A rising began at Palermo in April 1860 against the Bourbon government of the Two Sicilies, whose young king Francis II had succeeded the previous year.

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.

April 1860 — A rising begins at Palermo against Bourbon rule.
It supplies the occasion and, in failing, the reason Garibaldi was asked to intervene. (Garibaldi's expedition to Sicily and Naples)
May 1860 — The Thousand land at Marsala; Calatafimi is won within a week.
It is the point at which an expedition nobody in Turin expected to succeed becomes a serious military fact. (Garibaldi's expedition to Sicily and Naples)
September 1860 — Piedmont invades the Papal States and wins at Castelfidardo.
It is Cavour's decisive act of the year and its purpose was to reach Garibaldi before he reached Rome. (The great powers, Cavour's intervention and the Kingdom of Italy)
26 October 1860 — Garibaldi meets Victor Emmanuel near Teano and hands over his conquests.
It settles that the south is annexed rather than federated, and that the volunteers have no place in the new state. (The great powers, Cavour's intervention and the Kingdom of Italy)
