March of Ivrea

Upon the deposition of the Carolingian king Charles the Fat by his nephew Arnulf of Carinthia in 887, the power in Italy was assumed by the Unruoching margrave Berengar of Friuli, who received the Iron Crown of the Lombards from the hands of Archbishop Anselm II of Milan.

Arnulf, King of East Francia marched against Italy to gain the Lombard crown for himself and Berengar chose to pay homage to him, which led to discord with the Italian nobility.

The initial Eporedian march consisted of Piedmont and most of the Ligurian coast with the counties of Acqui, Alba, Asti, Bredulo [it], Auriate, Turin, Ivrea, Vercelli, Pombia, Stazzona, Bulgaria, Lomello, Savona, and Ventimiglia.

Anscar remained a loyal supporter of Guy and his son Lambert, even when King Arnulf, called by Pope Formosus.

When Lambert was deposed in 896 however, Anscar turned to his rival Berengar of Friuli, who managed to secure his rule in Italy after Arnulf's death in 899.
