The name of Kurszán[edit]
According to some historians, such as Gyula Kristó, it is wrong to call the conquering prince "Kurszán". Western sources refer to the leader of the Hungarians as "Kusal", and Georgius Monachus Continuatus (the successor to the Chronicle of George the Friend) says that he was "Kusanes", who received Byzantine envoys alongside Árpád. In earlier times, this person was unanimously identified with the son of Könd, Curzan, mentioned in the Gesta Hungarorum. Later, however, many questioned the correspondence of the two names and thus the identity of the two persons. However, we must also take into account that the name Kurszán was written by chroniclers who did not know Hungarian, and even within the same chronicle it happened that a foreign name was written in different forms.[5]
In the Western chronicles of 902-904 the names Chussal and Chussol are mentioned, while according to András Róna-Tas the original name was Kuszal (Küszel?), possibly Kuszan (Küszen?). The name Kurszán seems to be a "historian's tradition" in the same way as the name of Prince Géza.[5]
Hungarian conquest[edit]
He had a crucial role in the Hungarian Conquest (Honfoglalás).[6] In 892/893 together with Arnulf of Carinthia he attacked Great Moravia to secure the eastern borders of the Frankish Empire. Arnulf gave him all the captured lands in Moravia. Kurszán also occupied the southern part of Hungary that had belonged to the Bulgarian Kingdom. He entered into an alliance with the Byzantine emperor Leo VI after realizing the country's vulnerability from the south. Together they surprisingly defeated the army of Simeon I of Bulgaria.
In the summer of 904 Louis the Child invited Kurszán and his entourage to negotiate at the river Fischa. All were murdered[7][8] there. From this point Árpád became the only ruler[9] and occupied some of the territory of his former partner. The Kurszán family settled near Óbuda where they built Kurszánvára (meaning Castle of Kurszán). After Kurszán's death, they lived under the name Kartal.
There are toponymic traces of Kurszán on the right side of the Danube.[10]
