Important archaeological finds such as spear cusps, axes, and chipped flint are evidence of the existence of a stable population in the hilly area north of Novara as early as the Neolithic period.
From the Iron Age, on the other hand, are artifacts unearthed in the area bordering the Ticino River that attest to the existence of indigenous Golasecchian villages of Celto-Ligurian origin that probably maintained trade relations with the Celts beyond the Alps and with the Etruscans of the Mediterranean.
The first settlement nucleus of Bellinzago arose in Roman times, and it cannot be ruled out that inhabitants belonging to the Golasecca culture moved to the Roman settlement and together gave birth to the town of Bellinzago.
In the late Carolingian age it saw its greatest splendor and became the most prominent settlement among those placed in the area between Agogna and Ticino.
In 1360 the castle at the center of Bellinzago was razed to the ground by the troops of Galeazzo II Visconti and was rebuilt only in 1397; in the 16th century the castle was inhabited by the Visconti of Aragon and in the 18th it passed to the Florios of Romagnano until the building was demolished by order of the Demarchi in the year 1822.
At the end of the 13th century and the beginning of the 14th, it passed from the Biandrate seigniory to the political dominance of the City of Novara.
In the Napoleonic era, the municipality was restored and an adequate water supply network was created, which was later crucial to the development of rice cultivation in the Terdoppio valley.
The return of the Savoy in 1814, Novara and Novarese found themselves at the center of the historical events of the Risorgimento, especially those related to the First War of Independence.
The towns in the area thus moved toward state unification and toward an organization that became increasingly enlarged both territorially and economically. Alongside agriculture, in fact, the nineteenth century saw, even in Bellinzago, the formation of workshops and laboratories that created new social dynamics within the village.
