The Katir also (Kati, Kator, Kata) are a Nuristani tribe in Afghanistan and Pakistan.
The Katir/Katir or Kata Kafir group was numerically the most dominant group of the Siah-Posh (Persian "Black Wearer/Clothed") tribes. They owned approximately forty villages in the Bashgul valley and numbered about 40,000 (1890).
The upper part of the Bashgul Valley of Nuristan (Afghanistan) is known as Katirgul. It is called Lutdeh in Chitrali and Kantozi in Pashto.
According to George Scott Robertson, the Katir Siah-Posh clan settled in Katirgul valley was called Kamtoz (or Camtoz) in Pashto and Lutdehhchis in Chitrali (The Kafirs of the Hindukush, p 71). But American investigator Richard Strand's website suggests that the name Kamtoz/Kamtozi may apply to all Katirs of the former Siah-Posh group, including the Ramguli and Kulam Katirs [1].
Alternative names for Kamtoz are Camtozi, Kantozi. Despite their fiercely independent nature, the Katis, together with the Kom tribe, were tributary to the Mehtar of Chitral. The nature of this tributary relationship was inconsistent because the Katis and Koms would often raid Chitrali territory for livestock and head-hunting. In retaliation the Mehtars would invade the Bashgul Valley and enslave entire villages. During the reign of Mehtar Aman-ul-Mulk the relationship was formalized and the Kafirs would pay an annual tribute of slaves.
Numerous scholars have connected the names Katir/Kator/Kata and Kam/Kom with ancient Kambojas and identified the Kafirs, especially the Siah-Posh Kafirs, as having descended from ancient Kambojas.
