Persian refers to an ethnicity which is apart of the much larger Iranian group that inhabited present day Iran, Anatolia (now Turkey), The Caucaus, and Central Asia. The ancient Persians usurped the Median Empire and declared themselves the Achaemenid Pars(Achaemenid persians). Present day Iran now contains many ethnic groups: Kurds, Lurs, Lakis, Arabs, Armenians, and Persians. Most Iranians are mixed because years of conquest, imperialism, and being conquered themselves. They will however often most of the time identify with Persian -- as Persian is infact the dominant culture and language (Farsi/Parsi) within the country of Iran and also heavily influenced the Islamic Caliphates and Ottoman Empire that followed them.
"To say your are Iranian is to say refer to your Nationality. To say you are Persian is to refer to your culture and roots."

"The Turks and Arabs stole Persian culture, language, and science and claimed it as it's own"

The delicate and delightful art of taking a shit and getting directly into the shower. This promotes the the maximum level of cleanliness and increases the enjoyment of taking shits exponentially.

The term derives from the fact that Persians have extremely hair ass-holes and it is well known that simply wiping after a shit will in no way clean the ass-hole to a reasonable level. Therefore they are forced to shower after their shits to ensure cleanliness.
Dude, just did a Persian, it was fucking orgasmic.

Same thing as Iranian.

A person that is from Iran. A person who has an Iranian background.

The main Persian religion is Islam, and the other religion right behind it is Judaism. There are few Christian Persians.

According to the U.S. government, all Persians as well as all of the Middle Easterners are classified as white (yes, even Indians), even though they really aren't. They should be classified as Middle Eastern.

The Persian Muslims are desendents of Indo-Europeans, or the Aryans, and they were white. But look at them, Persian Muslims don't have pale skin anymore (they are tan, and brown, possibly near black!), they don't have blonde hair anymore (its dark brown and black), and their eyes are brown and black now (not hazel and blue). They ARE NOT Arab!! They speak Farsi.

The Persian Jews, unlike Persian Muslims, are desendents of the Hebrews from Ancient Israel, and they are very close to the Arabs, but they are NOT Europeans. The Persian Jews are are NOT Aryan. They look the same as the Muslims from Iran, they are exactly the same, except of the religions and ancestory. But the same. Their skin colors are tan and brown as well. And NO, Persian Jews aren't cheap (ALL PERSIANS ARE CHEAP AT TIMES), and a lot of Persians need nose jobs themselves, not just the stereotypical "big-nosed" Jew. They speak the same Farsi as Persian Muslims.
Being Persian is the same exact same thing as being Iranian.

An ethnicity making up around 60% of Iranians, and majority of Afghanistan and Tajikistan. Unlike how most Iranian Americans say, they claim that Iran is a persian nation, which is partially true, but using the terms persian and Iranian interchangeably is very ignorant. Persians are an Iranic race, so are Kurds, Gilaks, etc. Iran refers to a nation, so if you use iranian and persian interchangeably, you completely exclude all other Persians. Persian is a very different language then Azeri, Gilaki, Kurdish, etc. One thing to note is how people say Iran is not an arab nation, which is mostly true, however 1-4% of Iranians are arab.
Iranian American: “Yeah Iran isn’t arab, we’re persian. The words persian and Iranian are interchangeable”

Me: “only 60% of Iranians are persian! I’m not persian I’m Gilaki and Azari, and you completely forget the Persians of Afghanistan, Tajikistan and the ones in Uzbekistan, you are confusing nationality and ethnicity”

Persian = An ethinic group (roughly 50% of the population) living in Iran.

Iran = (Literally) land of the Aryans = Persia after 1935

Aryan, literally means an excellent or honorable person;

One of a primitive people supposed to have lived in pre-historic times, in Central Asia, east of the Caspian Sea, and north of the Hindoo Koosh and Paropamisan Mountains, and to have been the stock from which sprang the Hindoo, Persian, Greek, Latin, Celtic, Teutonic, Slavonic, and other races; one of that ethnological division of mankind called also Indo-European or Indo-Germanic.

Indo-Aryan: A member of one of the native races of India of Aryan speech and blood, characterized by tall stature, dolichocephaly (long head), fair complexion with dark hair and eyes, plentiful beard, and narrow and prominent nose.

Notes: Many of the Nazi leaders (Goebbels, Himmler, Speers, Rommel, Goering, Hess, Frank, etc.) were themselves brunettes. On the other hand, many of the Jews that were persecuted were whiter-skinned than many of the Nazi leaders:

"... Nevertheless, such theorists usually accepted that considerable variety of hair and eye colour existed even within the racial categories they recognised. Contrary to a popular myth, the Nazis themselves did not discriminate against Aryans who were not blond or blue-eyed, or had only one of these features. Adolf Hitler and most Nazi officials (not to mention most Germans at the time) had dark hair and were considered to be Aryans."

From en.wikipedia.org/wiki/Master_race
Persian nowadays refers to an ethnic group (some members of which have been mixed with other groups such as Turks and Arabs) living in Iran. Iranian However, is a name referring to the nationality of all the people living in, or originated from the country.
