The culture of Iran (Persian: فرهنگ ایران) or culture of Persia is one of the oldest and among the most influential in the world. Iran (Persia) is widely regarded as one of the cradles of civilization. Because of its dominant geopolitical position in the world, it has heavily influenced peoples and cultures situated in Southern and Eastern Europe to the west; Central Asia to the north; and South Asia, East Asia, and Southeast Asia to the east. Iranian history has significantly influenced the world through art, architecture, poetry, science and technology, medicine, philosophy, and engineering.
An "eclectic cultural elasticity" has been said to be one of the key defining characteristics of the Iranian identity and a clue to its historical longevity.
