A report on Achaemenid Empire, Sasanian Empire, Iranian peoples and Uzbekistan

The Achaemenid Empire, also called the First Persian Empire, was an ancient Iranian empire based in Western Asia that was founded by Cyrus the Great in 550 BC. It reached its greatest extent under Xerxes I, who conquered most of northern and central ancient Greece.

After defeating the last Parthian shahanshah, Artabanus IV, at the Battle of Hormozdgan in 224, he established the Sasanian dynasty and set out to restore the legacy of the Achaemenid Empire by expanding Iran's dominions.

The area was incorporated into the Iranian Achaemenid Empire and, after a period of Macedonian rule, was ruled by the Iranian Parthian Empire and later by the Sasanian Empire, until the Muslim conquest of Persia in the seventh century.

By the 5th century BC, the Kings of Persia were either ruling over or had subordinated territories encompassing not just all of the Persian Plateau and all of the territories formerly held by the Assyrian Empire (Mesopotamia, the Levant, Cyprus and Egypt), but beyond this all of Anatolia and Armenia, as well as the Southern Caucasus and parts of the North Caucasus, Azerbaijan, Uzbekistan, Tajikistan, Bulgaria, Paeonia, Thrace and Macedonia to the north and west, most of the Black Sea coastal regions, parts of Central Asia as far as the Aral Sea, the Oxus and Jaxartes to the north and north-east, the Hindu Kush and the western Indus basin (corresponding to modern Afghanistan and Pakistan) to the far east, parts of northern Arabia to the south, and parts of eastern Libya (Cyrenaica) to the south-west, and parts of Oman, China, and the UAE.

Later on, in 550 BCE, Cyrus the Great, would overthrow the leading Median rule, and conquer Kingdom of Lydia and the Babylonian Empire after which he established the Achaemenid Empire (or the First Persian Empire), while his successors would dramatically extend its borders.

In 427, he crushed an invasion in the east by the nomadic Hephthalites, extending his influence into Central Asia, where his portrait survived for centuries on the coinage of Bukhara (in modern Uzbekistan).

The Arabs conquered the Sassanid Empire of the Persians and seized much of the Byzantine Empire populated by the Kurds and others.

However, six centuries later Ardeshir I, founder of the Sasanian Empire, would consider himself Artaxerxes' successor, a grand testimony to the importance of Artaxerxes to the Persian psyche.

Currently, most of these Iranian peoples live in Iran, Afghanistan, the Caucasus (mainly Ossetia, other parts of Georgia, Dagestan, and Azerbaijan), Iraqi Kurdistan and Kurdish majority populated areas of Turkey, Iran and Syria, Tajikistan, Pakistan and Uzbekistan.

Sassanian settlements in Oman and Yemen testify to the importance of trade with India, but the silk trade with China was mainly in the hands of Sasanian vassals and the Iranian people, the Sogdians.
