Aleramici

The Aleramici were a Northern Italian noble and royal dynasty of Frankish^[1] origin which ruled various northwestern Italian territories in Piedmont and Liguria from the 10th to the 14th century, also reigning over the Kingdom of Jerusalem and the Kingdom of Thessalonica during the 12th and 13th centuries.

Their name derived from count Aleramo, proclaimed first Marquis of Central Liguria by emperor Otto the Great in 966. The Aleramici were divided in two main lines: the Marquises of Savona or Del Vasto, and the Marquises of Monferrato. In the 14th century the line of Monferrato ended in Irene of Montferrat, Empress of Constantinople, whilst the line of Savona carried on in multiple descending branches.
