List of rulers of Montferrat

The Marquises and Dukes of Montferrat^[1] were the rulers of a territory in Piedmont south of the Po and east of Turin called Montferrat. The March of Montferrat was created by Berengar II of Italy in 950 during a redistribution of power in the northwest of his kingdom. It was originally named after and held by the Aleramici. In 1574, Montferrat was raised to a Duchy by Maximilian II, Holy Roman Emperor (see Duchy of Montferrat).
