It
took Alexander only three years (from about 330-327 B.C.) to subdue the area
that is now Afghanistan and the adjacent regions of the former Soviet Union.
Moving eastward from the area of Herat, the Macedonian leader encountered
fierce resistance from local rulers of what had been Iranian satraps. Although
his expedition through Afghanistan was brief, he left behind a Hellenic
cultural influence that lasted several centuries.
Upon
Alexander's death in 323 B.C., his empire, which had never been politically
consolidated, broke apart. His cavalry commander, Seleucus, took nominal
control of the eastern lands and founded the Seleucid dynasty. Under the
Seleucids, as under Alexander, Greek colonists and soldiers entered the region
of the Hindu Kush, and many are believed to have remained. At the same time,
the Mauryan Empire was developing in the northern part of the Indian
subcontinent. It took control, thirty years after Alexander's death, of the
southeasternmost areas of the Seleucid domains, including parts of present-day
Afghanistan. The Mauryans introduced Indian culture, including Buddhism, to
the area. With the Seleucids on one side and the Mauryans on the other, the
people of the Hindu Kush were in what would become a familiar quandary in
ancient as well as modern history--that is, caught between two empires.
In the
middle of the third century B.C., an independent, Greek-ruled state was
declared in Bactria. Graeco-Bactrian rule spread until it included most of the
territory from the Iranian deserts to the Ganges River and from Central Asia
to the Arabian Sea by about 170 B.C. Graeco-Bactrian rule was eventually
defeated by a combination of the internecine disputes that plagued Greek
rulers to the west, the ambitious attempts to extend control into northern
India, and the pressure of two groups of nomadic invaders from Central
Asia--the Parthians and Sakas (perhaps the Scythians).
