Fajsz is the only known son of Jutotzas, the third son of Árpád who had led the Hungarian tribes' confederation at the time of their conquest of the Carpathian Basin between around 895 and 907.

In the period starting with Árpád's death, fundamental changes have happened in the government of the tribal confederation.

This time is marked more by the various tribes acting in concert for raids than with the tribes acting under a strong central authority.

Hungarian visitors at Constantinople—including Termatzus, a great-grandson of Árpád – had informed Emperor Constantine VII around 948 that the "first chief" of the Hungarians "comes by succession of Árpád's family.”

Constantine VII also mentions that Fajsz was the head of the confederation of the Hungarian tribes around 950.
