Wuzurgan

Shapur's death in 379 marked the start of a 125-year conflict between the wuzurgan and the Sasanian kings, who both struggled for power over Iran.

[2] During the reign of Yazdegerd I (r. 399–420), the wuzurgan were treated badly,[3] and after the latter's death in 420, they expelled all his sons and elected his nephew Khosrow as the ruler of the Sasanian Empire.

[6] Kavadh I, during his reign, began worshiping Mazdakism, a modified version of Zoroastrianism with influences from Manichaeism.

[1] Gushnaspdad, the kanarang of the Sasanian Empire, later urged the wuzurgan and other noble classes to execute Kavadh I, which they, however, refused to do.

During his reign, his minister Mah-Adhur Gushnasp, who was part of the wuzurgan class, in reality, controlled the Sasanian Empire.
