Árpád's name "is completely unknown" to all sources written in East Francia, which was one of the main powers of the Carpathian Basin at the turn of the 9th and 10th centuries. These sources, including the "Annales Alamannici" and the "Annales Eisnidlenses", only mention another Hungarian leader, Kurszán. According to Kristó and other historians, these sources suggest that Kurszán must have been the "gyula" commanding the Hungarian forces, while Árpád succeeded his murdered father as the sacred "kende". Proposing a contrasting theory, the Romanian historian Curta wrote that Kurszán was the "kende" and Árpád "gyula" only succeeded him when Kurszán was murdered by Bavarians in 902 or 904.
