... This region of hills in northern Italy has been populated from early in history. Etruscan peoples lived here, and they were already familiar with the cultivation of vines and the production of wine. According to Titus Livius, the Celts, attracted by the beauty of the location, invaded in about 400 B.C., driving out the Etruscans. Pliny the Elder wrote that the Ancient Romans settled permanently from 223 B.C., calling the area Cisalpine Gaul. After the Roman conquest, it seems to have taken the Latin name of Emerentiana, possibly derived from this Roman first name.Later, the area underwent the transformations that caused upheavals all over Europe from the 5th century A.D. on. The hills saw successive waves of invaders, the Ostrogoths, Longobards and Franks, causing destruction and devastation until the 8th century. In the early 10th century, the area suffered raids by Saracens, until 951 A.D., when the important feudal family, the Aleramici, initiated the powerful Marquisate of Monferrato.During the Middle Ages, the Latin name of the location can be found in number of documents, changing over the centuries as the language gradually evolved into its vernacular form:
- Marencanus (found in documents dated 1188)
- Maranzana (1199)
- Marenzanan (1257)
- Maransana (1353).
The definitive name of Maranzana was established no later than the 16th century, and no further variants appeared in later years.
In 1536, the Marquisate became part of the possessions of the Gonzaga family in Mantua, and in 1713 it changed hands once again, becoming a property of the Savoy king Vittorio Emanuele.
From then on, Maranzana was closely associated with the Savoy family and its history, taking part in the battles for Italian Independence, and the World Wars.
