The Árpád dynasty consisted of the members of the royal House of Árpád, also known as Árpáds. They were the ruling dynasty of the Principality of Hungary in the 9th and 10th centuries and of the Kingdom of Hungary from 1000 to 1301. The dynasty was named after the Hungarian Grand Prince Árpád who was the head of the Hungarian tribal federation during the conquest of the Carpathian Basin, c. 895. Previously, it was referred to as the Turul dynasty or kindred.

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.
