Although modern historians tend to deny this report on his reign, because other chronicles do not list him among the Hungarian rulers, there is consensus that even if Zoltán never ascended the throne, all monarchs ruling in Hungary from the House of Árpád after around 955 were descended from him.

[4] When Menumorut died, Zoltán inherited his father-in-law's duchy east of the river Tisza, which Anonymus claims was inhabited by "the peoples that are called Kozár".

Prince Zolta was a little lisping and pale, with soft, blonde hair, of middling stature; a warlike duke, brave in spirit, merciful to his subjects, sweet of speech, but covetous of power, whom all the leading men and warriors of Hungary loved marvelously.

Some time later, when Zolta was thirteen, all the leading men of the realm by their common counsel and of their equal wish appointed rectors of the kingdom beneath the prince to mend through the guidance of customary law the conflicts and lawsuits of litigants.

[3] Medievalist Tudor Sălăgean also says that Menumorut was a real person, the ruler of a one-time duchy inhabited by Romanians, Slavs and many other peoples at the turn of the 9th and 10th centuries.
