Afghanistan is comprised of a variety of ethnic groups called Afghans, the overwhelming majority of whom are Muslim, usually either follower of Sunni or Shia Islam.
The people of Afghanistan are related to many of the ethnic groups in Iran, Pakistan, Tajikistan, Turkmenistan, and Uzbekistan; the borders drawn between these groups are arbitrary.
For the most part, Afghans are farmers, although a significant minority follow a nomadic lifestyle. In the years since the Soviet invasion and the later civil war, a large number of Afghans have fled the country and become refugees in neighboring nations, most typically in Iran and Pakistan.
