Tajiks () are a Iranian ethnic group who are mostly found in Tajikistan, parts of Afghanistan, Uzbekistan, Pakistan and China. Alternative names for the Tajiks are Eastern Persian, Dehqan, and Farsiwan. After the Soviet invasion of Afghanistan in 1979, many Tajik refugees migrated to live in neighboring Iran and Pakistan. Most Tajiks are Sunni Muslims, but a few in remote mountain areas follow Ismailism.
