What is "akazai"

Akazai is a Pakhtoon or Pashtoon or Pathan tribe in northern Pakistan. It is a division of the Isazai clan within the Yousafzai tribe, which is regarded as one of the most powerful, famous, and respected tribes of Pashtoons. Military historian Colonel Harold Carmichael Wylly provided a personal perspective of the large Yousafzai tribe, stating, "The Yousafzai is an agriculturist, generally fine, well-limbed man of a good physique and appearance with great deal of race-pride, well dressed and cheery, while his hospitality is proverbial".
