The formal name of the Iranian state is Jomhuri-ye Islami-ye Iran , the Islamic Republic of Iran. The terms "Iran" as the designation for the civilization, and "Iranian" as the name for the inhabitants occupying the large plateau located between the Caspian Sea and the Persian Gulf have been in continual use for more than twenty-five hundred years.

These two deserts dominate the eastern part of the country, and form part of an arid landscape extending into Central Asia and Pakistan.
