Oxiana

For the Australian mining company, see Oxiana Limited.

Oxiana is the region surrounding the Amu Darya River which flows along Afghanistan's northern border separating it from Tajikistan and Uzbekistan before turning northwest into Turkmenistan to the Aral Sea. In ancient times, the river was known as the Oxus in Greek. The area was known to the Greeks as Bactria from the name of its capital and central city of Bactra.

Robert Byron wrote about Oxiana in his book The Road to Oxiana describing his ten-month-long journey to Persia and Afghanistan in 1933–34 and visited the remains of Bactra at Balkh.
