Most of the history of Treville was written down by Prof. Giuseppe Spina (1928-2003) in his book "Treville - Vicissitudes of a Small Village of the Basso Monferrato" (Comune of Treville ed., 1994).
    

We don't have information about the origin of the name Treville: the most ancient acts speak about "TRIVILLA", which allows us to guess that, during the XI-XII centuries, three settlements existed on the site. Alessandro Alemanno suggests a roman origin of the toponym: from the roman personage, named Trebellius.

On the hill North of Treville, where now St. Quirico Church and the Crosa neighbood is located, probably a village named  Arliate, Arliato or Arriliato stood; it was the first village built in the present municipal territory of Treville.
 
For a long time,  the historical events of this region have only marginally touched on the life of Treville characterized by a rural economy.
 
The first document is a 1202 decree in which the Marquis Bonifacio Ist Aleramo entrusted the fiefdom to the noble Anselmo Musso of Paciliano. The local Treville Statutes date back to 1303 and are among the most ancient in the Monferrato. 
 
During the following centuries the fiefdom passed to different squires. In 1403 Teodoro Paleologo the First entrusted it to George Areccio and in 1435 the dominion was attributed to Giacomino of Biandrate. During the dominance of the Monferrato by the Gonzaga of Mantova it was sold to Giulio Strozzi (1590) and to Gerolamo Amorotto de Andreasi (1602). In 1699, Giacomo Bartolomeo Gozani acquired it. His family of businessmen became wealthy in Casale by coining money and owned many fiefdoms in the Monferrato. In local lore, the Gozani are best remembered for commissioning Palazzo Treville, the best Baroque building in Baroque in Casale Monferrato, and long the pride of the family. 
 
In 1713, Treville passed to the Savoia dynasty, which upon unification, became the royal family of Italy.
