Greco-Bactrian Kingdom
Strabo, who lived between 64 BC and 24 CE, explains that the tribes inhabiting the lands west of the Indus River were part of Ariana. This was around the time when the area inhabited by the Pashtuns was governed by the Greco-Bactrian Kingdom. From the 3rd century CE onward, they are mostly referred to by the name "Afghan" ("Abgan").
