Bactria (Bactriana) was the ancient Greek name of the country between the range of the Hindu Kush (Caucasus Indicus) and the Amu Darya (Oxus), with the capital Bactra (now Balkh). To the east, it was bordered by the ancient region of Gandhara in the Indian subcontinent. Bactria's inhabitants spoke one of the Iranian languages. Today's Iranian tribes. Modern authors have often used the name in a wider sense, as the designation of the whole eastern part of Iran.
It was in these regions, where the fertile soil of the mountainous country is surrounded by the Turanian desert, that the prophet Zoroaster preached and gained his first adherents. The sacred language in which the Avesta, the holy book of Zoroastrianism, is written, was once called "old Bactrian."
Whether Bactria formed part of the Median empire, we do not know; but it was subjugated by Cyrus and from then formed one of the satrapies of the Persian empire. After Darius III had been defeated by Alexander and killed in the ensuing chaos, his murderer Bessus, the satrap of Bactria, tried to organize a national resistance based on his satrapy.
But Bactria was conquered by Alexander without much difficulty; it was only farther in the north, beyond the Oxus, in Sogdiana, where he met with strong resistance. Bactria became a province of the Macedonian empire, and soon came under the rule of Seleucus, king of Asia.
The Macedonians (and especially Seleucus I and his son Antiochus I) founded a great many Greek towns in eastern Iran, and the Greek language became for some time dominant there. The paradox that Greek presence was more prominent in Bactria than in areas far more adjacent to Greece could possibly be explained by the supposed policy of Persian kings to deport unreliable Greek as colonists to this the most remote province of their huge empire.
The many difficulties against which the Seleucid kings had to fight and the attacks of Ptolemy II, gave to Diodotus, satrap of Bactria, the opportunity of making himself independent (about 255 BC) and of conquering Sogdiana. He was the founder of the Greco-Bactrian kingdom. Diodotus and his successors were able to maintain themselves against the attacks of the Seleucids; and finally Antiochus III the Great defeated by the Romans (190 BC).
The Bactrian king Euthydemus and his son Demetrius crossed the Hindu Kush and began the conquest of eastern Iran and the Indus valley. For a short time they wielded great power; a great Greek empire seemed to have arisen far in the East. But this empire was torn by internal dissensions and continual usurpations. When Demetrius advanced far into India one of his generals, Eucratides, made himself king of Bactria, and soon in every province there arose new usurpers, who proclaimed themselves kings and fought one against the other.
Most of them we know only by their coins, a great many of which are found in Afghanistan and India. By these wars the dominant position of the Greeks was undermined even more quickly than would otherwise have been the case. After Demetrius and Eucratides, the kings abandoned the Attic standard of coinage and introduced a native standard, no doubt to gain support from outside the Greek minority. In India, the syncretism went even further. King Milinda (Menander of India), known as a great conqueror, even converted to Buddhism. His successors managed to cling to power somewhat longer, but around AD 10 all of the Greek kings were gone.
The weakness of the Greco-Bactrian empire was shown by its sudden and complete overthrow, first by the Sakas, and then by the Yuezhi (who later became known as Kushans), who had conquered Daxia (= Bactria) by the time of the visit of the Chinese envoy Zhang Qian, c. 127BC.
But then its emergence, isolated thousands of miles from Greece, could only be described as a paradox. However, its cultural influences were not completely undone; an artistic style mixing western and eastern elements known as the Gandhara culture survived the empire for hundreds of years.
