The name of the town of Canino appeared for the first time in a Papal Bull of the ninth century A.C. dating back to Pope Leo IV.
Despite not having certain documents, the origin of Canino has to be tied to the nearby Etruscan town of Vulci.
The most supported hypothesis is that Canino was born as a small farming village, initially called “Pagus”, and that later was named after one of the most important families in the city of Vulci, the "Gens Caninia".
The incursions of the Romans and the gradual decline of the largest center of Vulci, drove the population to other centers including the original farming village of Canino, which over time took on increasing importance.
The city experienced a period of splendor with the Farnese family and is also remembered as the birthplace of Alessandro Farnese, better known as Pope Paul III.
In the early years of 800 it hosted Luciano Bonaparte, brother of Napoleon, who was given the title of Prince of Canino. His tomb actually lies within the Bonaparte Chapel, at the Collegiate of SS. John and Andrew Apostles, since the late 700s.
The titles of Prince of Canino and Musignano passed later to the members of the Torlonia Family.
