The first and biggest civilization started from Persia (Iran)
The Achaemenid Empire or Achaemenian Empire,also known as the First Persian Empire Old Persian, was the ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC. Based in modern-day Iran, it was the largest empire by that point in history, spanning a total of 5.5 million square kilometres (2.1 million square miles). The empire spanned from the Balkans and Egypt in the west, West Asia as the base, the majority of Central Asia to the northeast, and the Indus Valley to the southeast.
In the modern era, the Achaemenid Empire has been recognized for its imposition of a successful model of centralized bureaucratic administration, its multicultural policy, building complex infrastructure such as road systems and an organized postal system, the use of official languages across its territories, and the development of civil services, including its possession of a large, professional army. Its advancements inspired the implementation of similar styles of governance by a variety of later empires. And you call this barbaric Persian!
