Ismail dies on May 23, 1524, at the relatively young age of thirty-six.

He is buried in Ardabil, and is succeeded by his son Tahmasp.

Only ten years old and thus too young to rule in his own right, Tahmasp comes under the control of the Qizilbash.

The tribal rivalries between the Qizilbāsh, which had temporarily ceased before the defeat at Chaldiran, resurface in intense form immediately after the death of Ismāil.

Some of the tribes recognize a Qizilbash leader, Div Sultan Rumlu, as regent (atabeg) to the shah, but others dissent.
