Colonel H. C. Wylly (1858–1932) described these people in the following words:[1] 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.The Hassanzais are amongst The Black Mountain (Tor Ghar) Tribes; a division of the Isazai clan of the Yousafzai tribe.
The Hassanzais are further divided into following ten Sections:[3][4] The Hassanzais live on either side of the Indus; those cis-Indus occupy the most southern portion of the western slopes of Tor Ghar, while those trans-Indus live immediately opposite to them.
[5][better source needed] Like all other Pashtoons, Hassanzais have maintained their cultural identity and individuality.
They lead their lives strictly in accordance with code of ethics of Pashtunwali which comprises Manliness, Goodness, Gallantery, Loyalty and Modesty.
Hassanzais have also maintained the Pashtoon customs of Jirga (Consultative Assembly), Nanawati (Delegation pleading guilty), Hujhra (Large drawing room) and Melmastya (hospitality).
