List of ancient great powers
The Sassanid Empire is the name used for the fourth Iranian dynasty, and the second Persian Empire (226–651). The empire's territory encompassed all of today's Iran, Iraq, Armenia, Afghanistan, eastern parts of Turkey, and parts of Syria, Pakistan, and large parts of Caucasia, Central Asia and Arabia. During Khosrow II's rule in 590–628 Egypt, Jordan, Palestine, Lebanon were also briefly annexed to the Empire, as well as far west as western Asia Minor. The Sassanid era, encompassing the length of the Late Antiquity period, is considered to be one of the most important and influential historical periods in Iran. In many ways the Sassanid period witnessed the highest achievement of Persian civilization. The empire is furthermore known for being the arch-rival of the neighboring Roman–Byzantine Empire for a period of over 400 years. As the Parthians were replaced by the Sassanids, they carried on the already century long lasting Roman–Persian Wars, which would eventually become the longest conflict in human history.
Aryan
The name for the Sassanian Empire in Middle Persian is "Eran Shahr" which means "Aryan Empire". In the aftermath of the Islamic conquest in Iran, racialist rhetoric became a literary idiom during the 7th century, i.e., when the Arabs became the primary "Other" – the "anarya"s – and the antithesis of everything Iranian (i.e. Aryan) and Zoroastrian. But "the antecedents of [present-day] Iranian ultra-nationalism can be traced back to the writings of late nineteenth-century figures such as Mirza Fatali Akhundov and Mirza Aqa Khan Kermani. Demonstrating affinity with Orientalist views of the supremacy of the "Aryan peoples" and the mediocrity of the "Semitic peoples", Iranian nationalist discourse idealized pre-Islamic [Achaemenid and Sassanid] empires, whilst negating the 'Islamization' of Persia by Muslim forces." In the 20th century, different aspects of this idealization of a distant past would be instrumentalized by both the Pahlavi monarchy (In 1967, Iran's Pahlavi dynasty [overthrown in the 1979 Iranian Revolution] added the title Āryāmehr "Light of the Aryans" to the other styles of the Iranian monarch, the Shah of Iran being already known at that time as the Shahanshah ("King of Kings")), and by the Islamic republic that followed it; the Pahlavis used it as a foundation for anticlerical monarchism, and the clerics used it to exalt Iranian values vis-á-vis westernization.
