Pashtunistan (Pashto: پښتونستان, Pax̌tūnstān) or Pukhtunistan, meaning the "land of Pashtuns" or "land of Pukhtuns", is a term used to refer to the historical region inhabited by the indigenous Pashtun people of Afghanistan and Pakistan since at least the 1st millennium BC. Possibly since at least the 3rd century CE and onward, the region was mostly synonymous with, and recognized as, Afghanistan, and by the people in the Indian subcontinent as Pathanistan.
Pashtunistan was politically divided for administration in 1893 by the Durand Line, a disputed and poorly-marked border between Afghanistan and British India. Today, the Pashtun homeland stretches from areas east of the Hindu Kush mountain range in Afghanistan to areas west of the Indus River in Pakistan.
