Bactria (/ˈbæktriə/; Bactrian: βαχλο, Bakhlo), or Bactriana, was an ancient region in Central Asia. Bactria proper was north of the Hindu Kush mountain range and south of the Oxus river (modern Amu Darya), covering Afghanistan. More broadly, Bactria was the area which was located north of the Hindu Kush, west of the Pamirs and south of the Tian Shan, covering modern-day Tajikistan and Uzbekistan as well, with the Amu Darya flowing west through the centre.
