The Persian Empire expanded from Africa to China and also to India, until Alexander the Great came along. Persians have a long and eventful history. The Shah of Persia, in the 1930s, changed the name of the country back to its original name, "Iran".
Iran means "the land of the Aryans". So Hitler and all his little Nazi friends were quite awfully wrong in calling themselves Aryans. The closest people of Aryan decent are Iranians and Afghanis and they certainly do not have blue eyes, blond hair and white skin.
As a result of mass integration of various cultures from around the Middle East area, Iranians nowadays are multiracial, but they still take great pride in their country.
Persia was a very rich country, and to some extent, it still is. But the majority of people in Iran are of lower class. However, most Iranians are hard-working and very motivated people. When they immigrate to other countries, a lot of them lead a good lifestyle because they work hard to earn a high status in society. Persians do not settle for anything but first place.
Lots of Persians who immigrate to new countries start out working in small businesses and often times, they start from scratch. They quickly work their way up. Persians are very hard working people.
Iran was not perfect before the Islamic Revolution. Hence why there WAS an Islamic Revolution. The majority of people living in Iran were poor in the 20th century, while the Shah basked in riches. That's WHY they revolted.
Yes, Iran has had a rich past, but the lives of Iranians were not any better before the Islamic Revolution than they are now. They DID have more freedom, but there was still a great amount of dissatisfaction.
Mohammed Reza Shah tried to make the lives of Iranians better, but all his developments were centralized to the rich folks.
