The Pashtun tribes (Pashto: پښتانه قبايل), are tribes of the Pashtun people, a large Eastern Iranian ethnic group who speak the Pashto language and follow Pashtunwali, the social code of conduct for Pashtuns. They are found primarily in Afghanistan and Pakistan and form the world's largest tribal society, comprising over 60 million people and between 350 and 400 tribes and clans. They are traditionally divided into four tribal confederacies: the Sarbani (سړبني), the Bettani (بېټني), the Ghurghusht (غرغښت), the Karlani (کرلاڼي) and a few allied tribes of those that are Ismailkhel, Khel, Ludin, Sakzai, and Zai.
