Archaeological findings have proved that the area of Biandrate was already settled inRoman times, although no consensus exists about the existence of a Romanmunicipium here. After the fall of theWestern Roman Empire, Biandrate regained importance only from the 10th century, when its counts held large territories in the area. In 1025, Count Vibertus, after expanding the family's lands aroundVercelli andVal d'Ossola, obtained the title ofIvrea; such possessions were confirmed to his successor Guido II by EmperorConrad II. His successor Alberto I took part in theFirst Crusade. In his age, Biandrate is mentioned as afree commune.
His successor Guido Guidone was named by EmperorFrederick Barbarossa as imperial commander of the area and of theBishopric of Novara. He fought againstPavia but, after Barbarossa' defeat at thebattle of Legnano, he was attacked by theLombard League and Biandrate was destroyed. In 1232, the town was again razed to the ground by the counts of Novara. Later it was held by different families: (Visconti,Facino Cane,Sforza) after which it became part of theDuchy of Savoy.
