Answer:
Count Cavour (10 August 1810 – 6 June 1861) was a chief minister of the Kingdom of Piedmont-Sardinia and an important figure in the process of Italian unification in the 19th century.
<em>On 21 July 1858, he has entered into a secret agreement with, Napoleon III, the French Emperor</em>. Though this agreement was only verbal and left no concrete evidence, it is sometimes referred to as the <em>Treaty of Plombières</em>.
As a result of this agreement, France and Piedmont became allies in the confrontation with Austria. <u>Cavour received support from France with the goal to free Italian peninsula from Austrian influence and thus move further to Italian unification.</u>
