Pashto
History

Some linguists have argued that Pashto is descended from Avestan or a variety very similar to it, while others have attempted to place it closer to Bactrian. However, neither position is universally agreed upon. What scholars do agree on is the fact that Pashto is an Eastern Iranian language sharing characteristics with Eastern Middle Iranian languages such as Bactrian, Khwarezmian and Sogdian.

Compare with other Eastern Iranian Languages and Old Avestan:

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).

Abdul Hai Habibi believed that the earliest modern Pashto work dates back to Amir Kror Suri of the early Ghurid period in the 8th century, and they use the writings found in Pata Khazana. Pə́ṭa Xazāná (پټه خزانه) is a Pashto manuscript claimed to be written by Mohammad Hotak under the patronage of the Pashtun emperor Hussain Hotak in Kandahar; containing an anthology of Pashto poets. However, its authenticity is disputed by scholars such as David Neil MacKenzie and Lucia Serena Loi. Nile Green comments in this regard:

"In 1944, Habibi claimed to have discovered an eighteenth-century manuscript anthology containing much older biographies and verses of Pashto poets that stretched back as far as the eighth century. It was an extraordinary claim, implying as it did that the history of Pashto literature reached back further in time than Persian, thus supplanting the hold of Persian over the medieval Afghan past. Although it was later convincingly discredited through formal linguistic analysis, Habibi's publication of the text under the title Pata Khazana ('Hidden Treasure') would (in Afghanistan at least) establish his reputation as a promoter of the wealth andantiquity of Afghanistan's Pashto culture."

From the 16th century, Pashto poetry become very popular among the Pashtuns. Some of those who wrote in Pashto are Bayazid Pir Roshan (a major inventor of the Pashto alphabet), Khushal Khan Khattak, Rahman Baba, Nazo Tokhi, and Ahmad Shah Durrani, founder of the modern state of Afghanistan or the Durrani Empire. The Pashtun literary tradition grew in the backdrop to weakening Pashtun power following Mughal rule: Khushal Khan Khattak used Pashto poetry to rally for Pashtun unity and Pir Bayazid as an expedient means to spread his message to the Pashtun masses.

For instance Khushal Khattak laments in :

"The Afghans (Pashtuns) are far superior to the Mughals at the sword,

Were but the Afghans, in intellect, a little discreet.If the different tribes would but support each other,

Kings would have to bow down in prostration before them"
