This articles is about the tribal lineages. For tribal structure see Pashtun tribal structure.The Pashtun tribes (Pashto: پښتانه ټبرونه) form the world's largest tribal society. The Pashtun people are traditionally divided into four tribal confederacies: the Sarbani (سربڼي), the Bettani (بېټني), the Ghurghakhti (غرغښتي), and the Karlani (کرلاڼي).Folkloric genealogies trace the descent of the Pashtuns to Qais Abdur Rashid and his three sons Sarbaṇ (سربڼ), Beṭ (بېټ), and Ghurghax̌t (غرغښت).
