The Pamir Mountains are a mountain range in Central Asia formed by the junction or knot of the Himalayas, Tian Shan, Karakoram, Kunlun, and Hindu Kush ranges. They are among the world’s highest mountains, and since Victorian times, they have been known as the "Roof of the World", presumably a translation from Persian.
The Pamiri people of Gorno-Badakhshan Autonomous Province in the southeast, bordering Afghanistan and China, though considered part of the Tajik ethnicity, nevertheless are distinct linguistically and culturally from most Tajiks. Pamiris overwhelmingly speak a number of Eastern Iranian languages, including Shughni, Rushani, Khufi and Wakhi. Isolated in the highest parts of the Pamir Mountains, they have preserved many ancient cultural traditions and folk arts that have been largely lost elsewhere in the country.
