The Sassanid Empire, which existed from 224 to 651 CE, is often referred to as the "Sassanian Empire" in modern contexts. This name emphasizes its dynastic founder, Ardashir I, who established the dynasty. After the fall of the Sassanid Empire to the Arab conquests, the region became part of the Islamic Caliphate, and the historical significance of the Sassanids continues to influence Persian culture and identity.
Zarathustra was a Persian prophet since his family originated from Persia. Although he ran away, his teachings were spread around the Persian Empire first. Persian nobles and Persian aristocrats embraced the new religion first and allowed the religion to blossom.
Zoroastrianism was the new religion that developed during Darius's rule of the Persian Empire. It was founded by the prophet Zoroaster (Zarathustra) and emphasized the worship of Ahura Mazda as the supreme deity and the belief in a cosmic struggle between good and evil.
The new Babylonian empire under Belshazzar was defeated by the Persian forces led by Cyrus the Great in 539 BCE. The fall of Babylon occurred during a feast when Belshazzar ignored ominous signs, and the Persian army secretly diverted the Euphrates River to enter the city through its dry riverbed. This event marked the end of the Neo-Babylonian Empire and the rise of Persian dominance in the region.
