How did Iran get its name?

Answer 1

In order one needs to understand this, one needs to know about the history, which for some political reasons have been altered by historians.

Iran is the oldest civilization in Eurasia (Europe and Asia) nearly 8,000 years old, very much governed and like the Old Soviet Union. It spanned from Punjab, Keshmir to Germany, and the current Russia to The Arabian Sea, with their capital at "Hallil Rood", in Kerman, Iran. Iran means land of "Arians." Several Arian dynasties rulled Iran over time in the ancient time: Kianinan and Pishdadian, and Maad before the Persians took power. Most of the civilizations in the northern Europe, Central Asia and parts of Mediteranian Sea have an Iranian root.

The name Iran has appeared in Ferdossi Shahnameh which is a history mixed with the mythology of ancient Iran, which clearly indicates that the Persians (or Prussians) were the most dominant country in the union until Islam became the main religion in the Union. The Iranian religions have changed many times. Initially they worshiped "Mitra", the god of lights (the sun). Over time "Mitraism" changed to Christianity on the north and western part of the Union, and "Zorastranism", "Mazdakism", "Monnyism", and eventually to "Islam" in the southeastern part of the Union. All conventional religions in the world came from Mitraism.

Over time the Iranian civilization became a hybrid civilization. The Nortern and western parts became independent and mixed with the Mediteranian people (Romans) and the Eastern and southern parts mixed with Arabs, Central Asian Turks, and Indians (current India and Pakistan). The Persian states did not have "Estan" at the end of their names, but other states (countries) within the union like "Tajikestan, Tortaministan", "Arabestan" (Known as Arabia), "Kordestan", etc. At one time, racism became a major issue in the Union and the Persians were outnumbered by the non-Persians in the Union. Then Islam became the main religion in the union with a strong message: "All races are equal." The Iranians converted to Islam and formed the Abbasi Empire and took Islam to Europe, African and East Asia.

In the Western world, Persia was historically the common name for Iran. In 1935, Reza Shah asked foreign delegates to use the term Iran (the historical name of the country, used by its native people) in formal correspondence. Since then, in the Western World, the use of the word "Iran" has become more common. This also changed the usage of the names for the Iranian nationality, and the common adjective for citizens of Iran changed from Persian to Iranian. In 1959, the government of Shah Mohammad Reza Pahlavi, Reza Shah Pahlavi's son, announced that both "Persia" and "Iran" could officially be used interchangeably.[1] Nonetheless, the word "Iran" has replaced "Persia" in the common usage.
