question: Which country Jamasp's father is from?
context: Title: Jamasp
  Passage: Jamasp (also spelled Zamasp or Djamasp; ; "Jāmāsp") was Sasanian King of Kings of Iran from 496 to 498/9. He was a son of Peroz I and younger brother of Kavad I. Jamasp was installed on the Sasanian throne upon the deposition of the latter by the nobility and clergy.
  Title: Peroz I
  Passage: Peroz I (Middle Persian: 𐭯𐭩𐭫𐭥𐭰; New Persian: پیروز "Pirouz", lit. " the Victor") was the eighteenth king (shah) of the Sasanian Empire from 459 to 484. He was the son of Yazdegerd II  and brother of Hormizd III . Peroz seized the throne from his older brother Hormizd III, whose reign lasted just two years. During his reign, he successfully quelled a rebellion in Caucasian Albania in the west, and put an end to the Kidarites in the east. He was, however, less successful in handling the Hephthalites, who had taken the Kidarites' place. This eventually resulted in a disastrous defeat near Balkh, where Peroz was killed. The magnates—most notably Sukhra and Shapur Mihran—elected Peroz's brother, Balash, as the new shah.
