The House of Ivrea was a noble dynasty that ruled parts of northern Italy during the early Middle Ages. It emerged in the 10th century and played a significant role in the political landscape of the region, particularly in the Kingdom of Italy. The house is known for its connections to various royal families and its influence over local governance. Members of the House of Ivrea included several kings and influential figures, such as Berengar II of Italy. The dynasty's power began to decline in the 11th century, leading to the rise of other noble families and the eventual fragmentation of their territories.
