Foundation of the Achaemenid Empire, Farvardin 1. This date is marked in the Shahanshahi calendar as the commemoration of the beginning of the Achaemenid Empire. The Achaemenids were one of the earliest and largest empires in Iranian history, established with the rise of Cyrus the Great around the 6th century BCE. The empire expanded across vast territories in Western Asia, Egypt, and parts of Europe, becoming a major power in the ancient world. In the Shahanshahi calendar, Farvardin 1 symbolizes the official start of the empire and serves as a reminder of the unification and expansion of Iranian lands. Cyrus the Great, as the founder, played a significant role in shaping Iran’s political and cultural history through the conquest of Babylon and the creation of a new administrative system. The Achaemenid Empire, with a population estimated in the tens of millions and an advanced bureaucracy, became a model for later states. The inclusion of this observance in the Shahanshahi calendar was a decision made by the Pahlavi government in the modern era; the purpose of designating this day was to emphasize Iran’s historical legacy and highlight the role of the Achaemenids in forming national identity. The day was typically marked by cultural programs, speeches, and remembrance of the historical achievements of the Achaemenid dynasty.
