Ügyek, also known as Ugek or Ugec, was – according to the chronicler Anonymus – the father of Álmos, the first Grand Prince of the Hungarians. However, according to a conflicting source, Simon of Kéza, Előd was the father of Álmos, while the chronicler referred to Ügyek as Álmos' grandfather. He is the earliest known ancestor of the Árpád dynasty. He was said to be a Scythian, i.e. to be from Dentumoger, the homeland of the Magyars, which the chroniclers identify with Scythia, and use to refer both to the land and its inhabitants.

Álmos, also Almos or Almus, was—according to the uniform account of Hungarian chronicles—the first head of the "loose federation" of the Hungarian tribes from around 850. Whether he was the sacred ruler (kende) of the Hungarians or their military leader (gyula) is subject to scholarly debate. According to Constantine Porphyrogenitus, he accepted the Khazar khagan's suzerainty in the first decade of his reign, but the Hungarians acted independently of the Khazars from around 860. The 14th-century Illuminated Chronicle narrates that he was murdered in Transylvania at the beginning of the Hungarian conquest of the Carpathian Basin around 895.
