Boniface II of Montferrat

Boniface II “the Giant” (July 1202–1253) was Marquis of Montferrat from 1225, son of William VI and Berta di Clavesana. Taking power in 1226, he joined the Lombard League against Frederick II, and Alessandria defeated him in 1230. His wife Margaret of Savoy, married in 1235, bore William VII and Alessia.

Reconciled with the emperor in 1239, he received Thessalonica and became its titular king, but in 1245 submitted to Frederick at Turin. In 1253 Conrad IV granted him Casale Monferrato; days later, on 12 May, he died at Moncalvo.
