Ladislav of Naples, who in the first years of the fifteenth century laid claim to the Hungarian throne, made Hrvoje his deputy for this Dalmatian territory, calling him his Vicar General for the regions of Slavonia (in partibus Sclavonie). Thus, like Venice, the Neapolitans still considered the region simply "Slavonia," and Hrvoje seems to have had no objections to the nomenclature.
Ladislas of Naples, hoping to retain both this territory and Hrvoje's support, gave his blessing to Hrvoje's ambitions and recognized him as his deputy for this region.
Croatia retained its independence under native kings until 1102, when the crown passed into the hands of the Hungarian dynasty.
Liée désormais à la Hongrie par une union personnelle, la Croatie, pendant huit siècles, formera sous la couronne de saint Étienne un royaume particulier ayant son ban et sa diète.
