Margraves of Montferrat

Montferrat was a margraviate which was located between Turin and Milan. It was ruled by a collateral branch of the Byzantine imperial house from 1306. When this house became extinct Montferrat was after a few years of Spanish rule united with the duchy of Mantua. Later as a consequence of the Mantovan War of Succession the northern part of Montferrat was transferred to Savoy in 1631. The rest of Montferrat was united with Savoy in 1708 when its ruling dynasty became extinct.
