The first news of Tagliolo go back to the end of the first millennium, when in March 976 Othon I grants the feud of Monferrato to the Marquis Aleramo I. Across the centuries Tagliolo knew various feudatories, among whom the Spinola and the Doria, passing from the Republic of Genoa to the Duchy of Milan, to the Empire and to Spain. In 1498 Tagliolo finally became a possession of the Gentile family, which obtained the title of Counts of Tagliolo. In 1750, following the marriage of Teresa Gentile with Costantino Pinelli, the feud of Tagliolo went over to the Pinelli Gentile family, with the title of Marquis of Tagliolo.
