Was it ever possible for the Kingdom of Hungary to de facto disintegrate around the 14th century, that is, in the aftermath of the extinction of the main line of the Arpad dynasty? IOTL, after the death of Andrew III, the throne was contested between multiple pretenders, chiefly the Premyslid Wenceslaus of Bohemia and the Angevin Charles Robert (born in Naples). The latter was victorious, but subsequently had to subdue a number of provincial magnates that grew stronger as royal power in Hungary was in lapse, such as Amadeus Aba and Matthew Csak in modern Ukrainian Transcarpathia and Slovakia respectively. This Charles managed to do. But how could we make it so that the Kingdom of Hungary effectively disintegrates in a sort of interregnum? I'm imagining a scenario in which the King of Hungary becomes a symbolic office contested by a variety of pretenders (and still very weak when there's only one), while feudal magnates run amok. How could this happen, and what would be the consequences of a "Holy Roman" Hungary on the Late Middle Ages in Central and Eastern Europe?
