Called "beautiful Bactria, crowned with flags" in the Avesta, the region is considered, in the Zoroastrian faith, to be one of the "sixteen perfect Iranian lands" that the supreme deity, Ahura Mazda, had created. It was once a small and independent kingdom struggling to survive against nomadic Turanians. One of the early centres of Zoroastrianism, and capital of the legendary Kayanian dynasty, 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, ruled by a crown prince or an intended heir. Bactria was the centre of Iranian resistance against the Greek Macedonian invaders after the fall of the Achaemenid Empire in the 4th century BC, but eventually fell to Alexander the Great.

After the death of Alexander, Bactria fell to his general, Seleucus I. The Seleucids lost the region to the satrap Diodotus I, when he declared independence; thus marking the beginning of the Greco-Bactrian and Indo-Greek Kingdoms. By the 2nd century BC, Bactria was conquered by the Parthian Empire, and, in the early 1st century, by the Kushan Empire, believed to have been founded by the Yuezhi. Bactrian (natively known as ariao, 'Iranian'), an Eastern Iranian language, was the common language of Bactria and the surroundings areas, from ancient until early medieval times.

Shapur I, the second Sasanian King of Kings of Iran, conquered western parts of the Kushan Empire in the 3rd century, and the Kushano-Sasanian Kingdom was established. The Sasanians lost Bactria in the 4th century, but reconquered it in the 6th century.

The Islamization of Bactria began with the Muslim conquest of Iran in the 7th century. The capital city of Bactra was the centre of an Iranian Renaissance in the 8th and 9th centuries, and New Persian as an independent literary language first emerged in this region. The Samanid Empire was formed in Eastern Iran by the descendants of Saman Khuda, a Persian from Bactria, leading to the spread of the Persian language in the region, and the decline of Bactrian.

Etymology

The modern English name of the region is Bactria. Historically, the region was first mentioned in Avestan as Bakhdi in Old Persian. This later developed into Bāxtriš in Middle Persian and Baxl in New Persian. The modern name is derived from the Ancient Greek: Βακτριανή (Romanized Greek term: Baktrianē), which is the Hellenized version of the Bactrian endonym. Other cognates include βαχλο (Romanized: Bakhlo). بلخ (Romanized: Balx), Chinese 大夏 (pinyin: Dàxià), Latin Bactriana. The region was mentioned in ancient Sanskrit texts as बाह्लीक or Bāhlīka.

Wilhelm Eilers proposed that the region was named after the Balkh River (in Greek transliteration Βάκτρος) from underlying Bāxtri-, itself meaning 'she who divides', from the Proto-Indo-European root *bhag- 'to divide' (whence also Avestan bag- and Old Indic bháj-).

Bactria is the geographic location after which Bactrian camels are named.
