Yazdegerd II fought wars against which Central Asian people based in Bactria?
Yazdegerd II Yazdegerd II (Middle Persian: 𐭩𐭦𐭣𐭪𐭥𐭲𐭩 "Yazdākird", meaning "made by God"; Persianزدگرد‎ ‎ ), was the sixteenth Sasanian emperor of Iran. He was the successor and son of Bahram V (420–438) and reigned from 438 to 457. His name may also be spelled Yazdgard II. His reign was marked by wars against the Byzantine Empire in the west and the Hephthalite Empire in the east, as well as by his efforts and attempts to impose Zoroastrianism on the largest religious minority within the empire, namely the Christians.
Wars of Alexander the Great The wars of Alexander the Great were fought by King Alexander III of Macedon ("The Great"), first against the Achaemenid Persian Empire under Darius III, and then against local chieftains and warlords as far east as Punjab, India. Alexander the Great was one of the most successful military commanders of all time. He was undefeated in battle. By the time of his death, he had conquered most of the world known to the ancient Greeks. Although being successful as a military commander, he failed to provide any stable alternative to the Achaemenid Empire—his untimely death threw the vast territories he conquered into civil war.
