Ancient Iran, known as Persia, was home to one of the world's oldest civilizations, dating back to around 3200 BCE. It was characterized by its rich culture, advanced architecture, and significant contributions to art and science. The Elamites and later the Achaemenid Empire, founded by Cyrus the Great, played crucial roles in shaping the region's history. The Achaemenid Empire expanded across three continents, promoting trade and cultural exchange. It is famous for its administrative innovations and the construction of monumental sites like Persepolis. Ancient Iran's influence extended beyond its borders, impacting neighboring cultures and laying the groundwork for future empires.
