A second great figure unifying Italy was Giuseppe (Joseph) Garibaldi. In 1848, he led troops in the northern Italian states in a failed revolt against Austrian rule. The following year, he attempted to replace the pope's rule over Rome with a more liberal government. The effort failed when French troops sent by Napoleon III arrived to back the pope. As a result, Garibaldi, too, was exiled. Cavour In 1852, the Italian unification movement gained new life under Camillo di Cavour. This period, called the Risorgimento, or reawakening. saw King Victor Emmanuel II of Sardinia and Piedmont name Cavour prime minister. Cavour believed in constitutional monarchy and in industrial growth. He strengthened the economy of Piedmont, which bordered France and Switzerland in the northwest of Italy, so that it had the power to win Italian territory from Austria. Cavour's first move was to arrange a secret alliance with France and then provoke a war with Austria. When Austrian troops invaded Piedmont, the French aided the Italians. The 1859 treaty that ended the war ceded the northern Italian state of Lombardy to Piedmont. The Austrian invasion increased nationalist feelings across northern Italy. Rebellions broke out as Tuscany, Parma, and Modena demanded freedom from Austrian control and unification with Piedmont Austria agreed. The foundation for the Italian nation had been built.

Garibaldi's Return In May 1860, Garibaldi landed on the island of Sicily with an army of about 1.000 soldiers called Red Shirts. His fiercely nationalistic soldiers defeated the larger, professional army of the island's Bourbon rulers. Then Garibaldi and his army crossed over to mainland Italy, taking control of the southern third of the peninsula. Cavour sent the Piedmontese army to aid Garibaldi, helping him capture the Papal States in central Italy (but not Rome). Garibaldi and his Red Shirts transferred their conquered territory to Victor Emmanuel, who became King of Italy in March 1861.
In 1866, Prussia's victory over Austria in the Seven Weeks' War ended Austria's control over Venetia in Italy's northeast. Then, in 1870 during the Franco-Prussian War, the French withdrew their troops from Rome and Italian troops moved in. In 1871, for the first time in many centuries, the entire peninsula was part of the same state. The leaders of unification were honored: Mazzini as the soul, Cavour as the brains, and Garibaldi as the sword.
What is a plausible claim about their reasons for trying so many times? written like a 8th grader short

A plausible claim about their reasons for trying so many times is that they were all passionate about freeing Italy from foreign rule and creating a unified nation. They each had different strengths - Mazzini inspired the people, Cavour was strategic, and Garibaldi was a skilled military leader - and together they were determined to achieve their goal no matter how many times they faced setbacks. Their perseverance eventually paid off and Italy was finally unified in 1871.
