Persians [SEP] Introduction
The Persians are an Iranian ethnic group that make up over half the population of Iran. They share a common cultural system and are native speakers of the Persian language, as well as languages closely related to Persian. The ancient Persians were originally an ancient Iranian people who migrated to the region of Persis, corresponding to the modern province of Fars in southwestern Iran, by the ninth century BC. Together with their compatriot allies, they established and ruled some of the world's most powerful empires, well-recognized for their massive cultural, political, and social influence covering much of the territory and population of the ancient world.
