Iran is the only country that borders the Caspian Sea that was not part of the former USSR. The Caspian Sea is often considered the world's largest lake, and its surface is actually 92 ft (28 m) below mean sea level.
Iran is a independent country.....
Coalition of Iran's Independent Volunteers was created in 2008.
Never, although they were once close allies.
The world's largest lake is the Caspian Sea at 371,000 sq km which is completely enclosed by Russia, Iran, Kazakhstan, Turkmenistan and Azerbaijan. (My map only shows 5 independent states)
Iran came two thousand years after the ancient Greeks. The two couldn't be less alike. Ancient Greece was 2,000 independent city-states spread around the Mediterranean and Black Seas. Iran was and is a unified state in the Middle East.
The first modern Persian Empire was the Safavid Empire in 1501 and Iran has remained more-or-less independent since then, but Iran has been the center of numerous other empires that may not have been headquartered within Iran's boundaries.
Shah Reza Khan is the one who modernized Iran and made it fully independent. He is criticized by some of his detractors as having oppressed some ethnic groups which stunted the development of Iran.
