=== Wars in the east ===
Not much is known about Kavad's wars in the east. According to Procopius, Kavad was forced to leave for the eastern frontier in 503 to deal with an attack by "hostile Huns", one of the many clashes in a reportedly lengthy war. After the Sasanian disaster in 484, all of Khorasan was seized by the Hephthalites; no Sasanian coins minted in the area (Nishapur, Herat, Marw) have been found from his first reign.{{sfn|Schindel|2013a|pp=136–141}} The increase in the number of coins minted at [[Hyrcania|Gorgan]] (which was now the northernmost Sasanian region) during his first reign may indicate a yearly tribute he paid to the Hephthalites.{{sfn|Potts|2018|pp=296–297}} During his second reign, his fortunes changed. A Sasanian campaign in 508 led to the conquest of the Zundaber (Zumdaber) Castellum, associated with the temple of az-Zunin in the area of ad-Dawar, situated between [[Lashkargah|Bust]] and [[Kandahar]].{{sfn|Potts|2018|p=297}} A Sasanian coin dating to 512/3 has been found in Marw. This indicates the Sasanians under Kavad had managed to re-conquer Khorasan after successfully dealing with the Hephthalites.{{sfn|Schindel|2013a|pp=136–141}}
