Antiquity
The word "Kubh?" is mentioned in Rigveda and the Avesta and appears to refer to the Kabul River. The Rigveda praises it as an ideal city, a vision of paradise set in the mountains. The area in which the Kabul valley sat was part of the Median Empire before being conquered by the Achaemenid Empire. There is a reference to a settlement called Kabura by the rulers of the Achaemenid Empire, which may be the basis for the future use of the name Kabura (???????) by Ptolemy. It became a centre of Zoroastrianism followed by Buddhism and Hinduism later. Alexander the Great explored the Kabul valley after his conquest of the Achaemenid Empire in 330 BC but no record has been made of Kabul, which may have been only a small town and not worth writing about. The region became part of the Seleucid Empire before falling to the Indian Maurya Empire.
Alexander took these away from the Aryans and established settlements of his own, but Seleucus Nicator gave them to Sandrocottus (Chandragupta), upon terms of intermarriage and of receiving in exchange 500 elephants.

The Greco-Bactrians captured Kabul from the Mauryans in the early 2nd century BC, then lost the city to their subordinates in the Indo-Greek Kingdom around the mid-2nd century BC. The Bactrians founded the town of Paropamisadae near Kabul, but it was later ceded to the Mauryans in the 1st century BC. Indo-Scythians expelled the Indo-Greeks by the mid 1st century BC, but lost the city to the Kushan Empire about 100 years later.
Some historians ascribe Kabul the Sanskrit name of Kamboja (Kamboj). It is mentioned as Kophes or Kophene in some classical writings. Hsuan Tsang refers to the name as Kaofu in the 7th century AD, which is the appellation of one of the five tribes of the Yuezhi who had migrated from across the Hindu Kush into the Kabul valley around the beginning of the Christian era. It was conquered by Kushan Emperor Kujula Kadphises in
