اردشیر بابکان was the founder of the ساسانیان dynasty in ancient Persia, ruling from 224 to 241 CE. He is known for unifying the Persian Empire after defeating the last پارتی king, establishing a centralized government and promoting Zoroastrianism as the state religion. Under his leadership, the empire experienced significant cultural and economic growth. اردشیر implemented reforms in administration and military organization, which strengthened the empire's stability. His legacy continued through his descendants, notably his son شاپور اول, who expanded the empire further.
