The Chagharzais or Chagarzais are a division of the Malaizai clan of the Yousafzai tribe. Colonel Harold Carmichael Wylly, 1858–1932, a British military historian described these people in the following words:
Chagharzais are the descendants of Chaghar or Chagar (Chagharzai), the son of Malay (Malaizai) who was one of the sons of Yousaf (Yousafzai). They are divided into following sub-divisions:[1]
The three Chagarzai sub-divisions are further divided into following Sections and Sub-sections:[2] [3]
| Sub Clan | Section | Sub-section (Khel) |
| Chagharzai | Ferozai | Bai Khel, Juna Khel, Maki Khel |
| Basi Khel | Daud Khel, Shahu Khel, Khwaja Khel, Kalandar Khel, Kasan Khel and Babujan Khel. | |
| Nasrat Khel | Hanju Khel, Haider Khel, Lukman Khel and Badha Khel | |
The Chagharzais occupy the country on either side of the Indus River. They are located on the western slopes of Tor Ghar (Black Mountain), to the north of the Akazais. The southern boundary of the Chagarzais is contiguous with that of the Akazais. It follows the spur of the Tor Ghar running from the Machai Sar (peak) to the Indus bank — the southern face of the spur belonging to the Akazais and the northern to the Chagarzais. On the west and north the Indus forms the boundary, while on the east the Chagarzais are bounded by the territory of the Deshiwals and of the Pariari Saiyids.[4]
Chagharzais have maintained their cultural identity and individuality. They lead their lives strictly in accordance with code of ethics of Pashtunwali which comprises Manliness, Goodness, Gallantry, Loyalty and Modesty. Chagharzais maintain the Pashtun customs of Jirga (consultative assembly), Nanawati (delegation pleading guilty), Hujhra (large drawing room) and Melmastya (hospitality).[5]
On 28 January 2011, Tor Ghar became the 25th District of Khyber Pakhtoonkhwa.[6] Judba is the District Headquarters of this newly born district. The three Tehsils (subdivision) of this district are; Judba, Kandar Hassanzai and Mada Khel. Most of the Chagharzai areas come under the Judba tehsil.
