 The Pakthas were one of the tribes that fought against Sudas in the Dasarajna the Battle of the Ten Kings (dāśarājñá), a battle alluded to in Mandala 7 of the Rigveda (RV 7.18.7).Heinrich Zimmer connects them with a tribe already mentioned by Herodotus ("Pactyans"), and with Pashtuns in Afghanistan and Pakistan.The Greek historian Herodotus mentioned a people called "Pactyan" living on the eastern frontier of the Achaemenid Arachosia Satrapy as early as the 1st millennium BCE.
