A report on Achaemenid Empire, Alexander the Great and Zoroastrianism

The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great founded the Achaemenid Persian Empire, which became one of the largest empires in history and has been described as the world's first effective superpower.

The Achaemenid Empire fell to Alexander the Great in the fourth century BC and was subsequently divided into several Hellenistic states.

Historically, early Iranian religions such as the Proto-Iranic religion and the subsequent Zoroastrianism and Manichaeism were the dominant religions in Iran, particularly during the Median, Achaemenid, Parthian, and Sasanian eras.

Sogdiana was also a province of the Achaemenid Empire, and listed on the Behistun Inscription of Darius the Great.

Sogdiana was first conquered by Cyrus the Great, the founder of the Achaemenid Empire, and then was annexed by the Macedonian ruler Alexander the Great in 328 BC. It would continue to change hands under the Seleucid Empire, the Greco-Bactrian Kingdom, the Kushan Empire, the Sasanian Empire, the Hephthalite Empire, the Western Turkic Khaganate and the Muslim conquest of Transoxiana.

While originally following the faiths of Zoroastrianism, Manichaeism, Buddhism and, to a lesser extent, Nestorian Christianity from West Asia, the gradual conversion to Islam among the Sogdians and their descendants began with the Muslim conquest of Transoxiana in the 8th century.

The territory that now constitutes Tajikistan was previously home to several ancient cultures, including the city of Sarazm of the Neolithic and the Bronze Age and was later home to kingdoms ruled by people of different faiths and cultures, including the Oxus Valley Civilisation, Andronovo Culture, Buddhism, Nestorian Christianity, Hinduism, Zoroastrianism, Manichaeism and Islam.

The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sasanian Empire, Hephthalite Empire, Samanid Empire and the Mongol Empire.

After the region's conquest by Alexander the Great it became part of the Greco-Bactrian Kingdom, a successor state of Alexander's empire.

Instead, the term "Hellenistic" refers to that which is influenced by Greek culture, in this case, the East after the conquests of Alexander the Great.

After Alexander the Great's invasion of the Achaemenid Empire in 330 BC and its disintegration shortly after, the Hellenistic kingdoms were established throughout south-west Asia (Seleucid Empire, Kingdom of Pergamon), north-east Africa (Ptolemaic Kingdom) and South Asia (Greco-Bactrian Kingdom, Indo-Greek Kingdom).

The Hellenistic influence in Iran was significant in terms of scope, but not depth and durability—unlike the Near East, the Iranian–Zoroastrian ideas and ideals remained the main source of inspiration in mainland Iran, and was soon revived in late Parthian and Sasanian periods.

One of the early centres of Zoroastrianism and capital of the legendary Kayanian kings of Iran, Bactria is mentioned in the Behistun Inscription of Darius the Great as one of the satrapies of the Achaemenid Empire; it was a special satrapy and was ruled by a crown prince or an intended heir.

Bactria was the centre of Iranian resistance against the Macedonian invaders after the fall of the Achaemenid Empire in the 4th century BCE, but eventually fell to Alexander the Great.

Persepolis (, Pārsa; ) was the ceremonial capital of the Achaemenid Empire (c.

The complex was taken by the army of Alexander the Great in 330 BC, and soon after the wooden parts were completely destroyed by fire, very likely deliberately.

The Book of Arda Wiraz, a Zoroastrian work composed in the 3rd or 4th century, describes Persepolis' archives as containing "all the Avesta and Zend, written upon prepared cow-skins, and with gold ink", which were destroyed.

The Old Avestan texts known as the Gathas are believed to have been composed by Zoroaster, the founder of Zoroastrianism, with the Yaz culture (c.

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.

More than a century later, a prince of Macedon (which itself was a subject to Persia from the late 6th century BCE up to the First Persian invasion of Greece) later known by the name of Alexander the Great, overthrew the incumbent Persian king, by which the Achaemenid Empire was ended.

The region that comprises the modern state of Pakistan was the realm of multiple empires and dynasties, including the Achaemenid; briefly that of Alexander the Great; the Seleucid, the Maurya, the Kushan, the Gupta; the Umayyad Caliphate in its southern regions, the Hindu Shahis, the Ghaznavids, the Delhi Sultanate, the Mughals, the Durranis, the Sikh Empire, British East India Company rule, and most recently, the British Indian Empire from 1858 to 1947.

Successive ancient empires and kingdoms ruled the region: the Persian Achaemenid Empire (around 519 BCE), Alexander the Great's empire in 326 BCE and the Maurya Empire, founded by Chandragupta Maurya and extended by Ashoka the Great, until 185 BCE.

There are also people in Pakistan who follow other religions, such as Sikhism, Buddhism, Jainism and the minority of Parsi (who follow Zoroastrianism).

Xerxes I ( Xšayār̥šā; ; c. 518 – August 465 BC), commonly known as Xerxes the Great, was the fourth King of Kings of the Achaemenid Empire, ruling from 486 to 465 BC. He was the son and successor of Darius the Great ((r.

Much of Xerxes' bad reputation is due to propaganda by the Macedonian king Alexander the Great ((r.

Persian princes were also taught on the basics of the Zoroastrian religion, to be truthful, have self-restraint, and to be courageous.
