most notably the Durrani, speak (Kandahari Pashto) a "soft" dialect of Pashto; while northwestern Sarbani tribes such as Gigyani tribe, Yousafzai Khalil and Mohmand tribes etc., most notably they speak (Peshawari Pashto) Pashto a "hard" dialect of Pashto. Both of them are considered upper class dialects. In addition, a small section of the Tarin clan of the Sarbani living east of Quetta speak the distinctive Wanetsi (Tareeno) dialect, which is considered by some modern scholars to be distinctive enough to be classified as its own language. History The origin of Pashtuns is unclear but historians have come across references to various ancient peoples called Pakthas (Pactyans) between the 2nd and the 1st millennium, who may be their early ancestors. Often characterised as a warrior and martial race, their history is mostly spread among various countries of South and Central Asia, centered on their traditional seat of power in medieval Afghanistan. One theory suggests that the modern Ghilji lineages descended from the medieval Khalaj or Khilji tribe. Some Bettani lineages, however, are said to have descended in part from the medieval Ghorid people. The Bettani are named after their folkloric leader or ancestor, Shaikh Bet Baba (claimed to be among the first Pashto-language poets), who lived in the Altamur range, located between the Logar and Zurmat valleys. He is reported to have been buried in Ghazni. In the 15th century, the Bettani are known to have mainly inhabited the Logar, Zurmat, and Ghazni regions. Subsequently, many of their lineages settled to the northeast, spreading up to the Damaan Valley, Mianwali, and parts of the present-day Hazara Division of Khyber Pakhtunkhwa, Pakistan, in the east, and parts of Kunduz Afghanistan in the north. In the 19th century, the traditional way of life of the Bettani combined small-scale irrigated agriculture with seasonal nomadism or seminomadism. They engaged in pastoral migrations, along the mountain slopes in summers, and inversely, towards the Indus plains in winters. From the 13th century, various Khilji dynasties and ruling entities took control in the Bengal and Delhi Sultanates of the Indian subcontinent. In the 15th century, the Lodi tribe founded the Lodi dynasty, the last dynasty to rule the Delhi Sultanate. In the 16th century, the Sur Empire with its capital at Delhi was founded by Sher Shah Suri, a member of the Sur clan of the Bettani confederacy. Between 1709 and 1738, the Hotak clan of the Ghilji
