The Yidgha language is a Pamir language spoken in the Upper Lutkuh Valley (Tehsil Lotkuh) of Chitral, Khyber Pakhtunkhwa west of Garam Chashma in Pakistan. Yidgha is similar to the Munji language spoken on the Afghan side of the border.

The Garam Chashma area became important during the Soviet invasion of Afghanistan because the Soviets were unable to stop the flow of arms and men back and forth across the Dorah Pass that separates Chitral from Badakshan in Afghanistan. Almost the entire Munji-speaking population of Afghanistan fled across the border to Chitral during the War in Afghanistan.

The Pamir is a high plateau sometimes called "the roof of the world" that joins Pakistan, Afghanistan, Tajikistan, China and Kashmir. Marco Polo is believed to have crossed the Pamir Mountains on his way to China.

The Yidgha language has not been given serious study by linguists, except that it is mentioned by Georg Morgenstierne (1926), Kendall Decker (1992), Rehmat Aziz Chitrali and Badshah Munir Bukhari (2005). A 280-page joint description of Yidgha and Munji (descriptive and historical phonetics and grammar, glossary with etymologies where possible) is given by Morgenstierne (1938).

Pamiri (Tajik: Помири, Persian: پامیری‎) is the name of an Iranian ethnic group in the Gorno-Badakhshan Autonomous Province of Tajikistan and Badakhshan Province of Afghanistan.

The Pamiris are composed of people who speak the Pamiri languages, the indigenous language in the Gorno-Badakhshan autonomous province, and adhere to the Ismaili sect of Shia Islam. The Pamiris share close linguistic, cultural and religious ties with the people in Badakhshan Province in Afghanistan, the Sarikoli speakers in Taxkorgan Tajik Autonomous County in Xinjiang Province in China, the Wakhi speakers in Afghanistan and the Wakhi speakers in Upper Hunza Gojal region of Northern mountainous areas of Pakistan. In the Pamiri languages the Pamiris refer to themselves as Pamiri or Badakhshani, a reference to the historic Badakhshan region where they live.

In China, Pamiris are referred to as ethnic Tajiks. In Afghanistan, they are recognized as ethnic Pamiris, and the Afghan National Anthem mention Pamiris (پاميريان Pāmiryān) in the list of ethnic groups of Afghanistan.
