one of the Abdali governors of Herat. Durrani Empire In 1747, Ahmad Shah Durrani established the Durrani Empire with its capital at Kandahar. He adopted the title Shāh Durr-i-Durrān, "King, Pearl of Pearls," and changed the name of his tribe "Abdali" to "Durrani" after himself. Ahmad Shah is now regarded as the founder of the modern state of Afghanistan. Within a few years, he extended his control from Khorasan in the west to Kashmir and North India in the east, and from the Amu Darya in the north to the Arabian Sea in the south. Barakzai dynasty In 1823, Emir Dost Mohammad Khan, who belonged to the Barakzai tribe of Durranis, founded the Barakzai dynasty centered at Kabul. Thereafter, his descendants ruled in direct succession until 1929 when King Amanullah Khan, under whom Afghanistan gained independence over its foreign policy from the British Raj, was forced to abdicate and his cousin Mohammed Nadir Shah was later elected king. The Barakzai dynasty ruled present-day Afghanistan until 1973 when Mohammed Zahir Shah, the last Barakzai king, was overthrown in a bloodless coup by his cousin Mohammed Daoud Khan. The coup ended the Barakzai kingdom and established the Republic of Afghanistan (1973—1978).

It is considered one of the most prestigious varieties of Pashto. This dialect retains archaic retroflex sibilants and , which have merged into other phonemes in other dialects. Southern Pashto also preserves the affricates and , which have merged into and in some dialects. The Tareen (Tarin) tribe is historically closely related to Durranis. Although most Tareens speak Southern Pashto, a small section of the Spin clan of Tareens living east of Quetta speaks the unique Wanetsi (Tareeno) dialect of Pashto, which is considered by some linguists to be distinctive enough to be classified as its own language. According to linguist Prods Oktor Skjaervo: "The Pashto area split into two dialect groups at a pre-literary period, represented today on the one hand by all the dialects of modern Pashto and on the other by Wanetsi and by
