What is "kurszan"

Kurszán (died 904), was a kende of the Magyars in the dual leadership with Árpád serving as a gyula. While kende was roughly correspondent to the Khazar title khagan, Árpád's role equated to the Khazar military title bek. In Latin sources he was referred to as rex and had a political status as a sacred king until he was massacred in a political plot of Western rulers and was temporarily succeeded by Árpád.
