This period of revolts ended during the reign of Béla I. Hungarian chroniclers praised Béla I for introducing new currency, such as the silver denarius, and for his benevolence to the former followers of his nephew, Solomon. The second greatest Hungarian king, also from the Árpád dynasty, was Ladislaus I of Hungary, who stabilized and strengthened the kingdom. He was also canonized as a saint. Under his rule Hungarians successfully fought against the Cumans and acquired parts of Croatia in 1091. Due to a dynastic crisis in Croatia, with the help of the local nobility who supported his claim, he managed to swiftly seize power in northern parts of the Croatian kingdom (Slavonia), as he was a claimant to the throne due to the fact that his sister was married to the late Croatian king Zvonimir who died childless.
