Afghanistan is an Islamic country. An estimated 80% of the population is Sunni, following the Hanafi school of jurisprudence; the remainder of the population--and primarily the Hazara ethnic group--is predominantly Shi'a. Despite attempts during the years of communist rule to secularize Afghan society, Islamic practices pervade all aspects of life. In fact, Islam served as a principal basis for expressing opposition to communism and the Soviet invasion. Islamic religious tradition and codes, together with traditional tribal and ethnic practices, have an important role in personal conduct and dispute settlement. Afghan society is largely based on kinship groups, which follow traditional customs and religious practices, though somewhat less so in urban areas.
Arab rule gave way to the Persians, who controlled the area until conquered by the Turkic Ghaznavids in 998. Following Mahmud's short-lived dynasty, various princes attempted to rule sections of the country until the destructive Mongol invasion of 1219 led by Genghis Khan.
Following Genghis Khan's death in 1227, a succession of petty chiefs and princes struggled for supremacy until late in the 14th century, when one of his descendants, Tamerlane, incorporated Afghanistan into his own vast Asian empire.
In 1747, Ahmad Shah Durrani, the founder of what is known today as Afghanistan, established his rule. A Pashtun, Durrani was elected king by a tribal council after the assassination of the Persian ruler Nadir Shah at Khabushan in the same year. Throughout his reign, Durrani consolidated chieftainships, petty principalities, and fragmented provinces into one country. His rule extended from Mashad in the west to Kashmir and Delhi in the east, and from the Amu Darya (Oxus) River in the north to the Arabian Sea in the south.
European Influence
Habibullah, Abdur Rahman's son and successor, was assassinated in 1919. His third son, Amanullah, regained control of Afghanistan's foreign policy after launching the third Anglo-Afghan war with an attack on India in the same year. During the ensuing conflict, the war-weary British relinquished their control over Afghan foreign affairs by signing the Treaty of Rawalpindi in August 1919. In commemoration of this event, Afghans celebrate August 19 as their Independence Day.
