The language is nearly identical with Persian, were part of the ancient Persian Empire that was ruled by Darius I and later conquered by Alexander the Great (333 B.C.).
The Pamiris speak a different language and belong to the Ismaili Shiite sect of Islam, while Tajiks are Sunni. Gorno-Badakhshon is surrounded by mountains, and is isolated for most of the year. The isolation of the Pamiri has kept them close to their ancient traditions.
