Answer 2

Count Cavour, as he's often known, was the Prime Minister of the Kingdom of Piedmont and Sardinia. He's largely responsible for creating the nation of Italy. He forged an alliance with France which meant that his kingdom got Lombardy as a reward for fighting along with the French against the Austrians.

Then Garibaldi went into Sicily and overthrew the King of Naples. Because he was a radical and republican Cavour moved quickly to "welcome" the liberated lands into what he now called the Kingdom of Italy.
