Siyawush

[1][2] With the aid of his sister and close-friend Siyawush, Kavad managed to free himself from imprisonment, and went to the court of the Hephthalite king, where he took refuge.

[1] Jamasp, including the nobility and clergy did not put any resistance as they wanted to prevent another civil war.

[3] Kavad's reclaim of his throne displays the troubled circumstances of the empire, where in a time of anarchy a small force was able to overwhelm the nobility-clergy alliance.

[2] In c. 520, Kavad, in order to secure the succession of his youngest son Khosrow I, whose position was threatened by rival brothers and the Mazdakite sect, proposed that the Byzantine Emperor Justin I adopt him.

[8] Further accusations were made towards Siyawush, which included the reverence of new deities and having his dead wife buried, which was a violation of Iranian laws.
