Durrani dynasty in the context of "Dost Mohammad Khan"

The First Anglo-Afghan War (Pashto: د افغان او انگرېز لومړی جنگ; Persian: جنگ اول افغان و انگلیس) was fought between the British Empire and the Emirate of Kabul from 1838 to 1842. The British initially successfully invaded the country taking sides in a succession dispute between emir Dost Mohammad Khan (Barakzai) and former King Shah Shujah (Durrani), whom they reinstalled upon occupying Kabul in August 1839. The main British Indian force occupied Kabul and endured harsh winters. The force and its camp followers were almost completely massacred during its 1842 retreat from Kabul.

The British then sent what was widely termed an "Army of Retribution" to Kabul to avenge the destruction of the previous forces. After recovering prisoners, they left Afghanistan by the end of the year. Dost Mohammed returned from exile in India to resume his rule.

Kandahar is a city in Afghanistan, located in the south of the country on Arghandab River, at an elevation of 1,010 m (3,310 ft). It is Afghanistan's second largest city, after Kabul, with a population of about 614,118 in 2015. It is the capital of Kandahar Province and the centre of the larger cultural region called Loy Kandahar.

The region around Kandahar is one of the oldest known areas of human settlement. A major fortified city existed at the site of Kandahar, probably as early as c. 1000–750 BC, and it became an important outpost of the Achaemenid Empire in the 6th century BC. Alexander the Great laid the foundation of what is now Old Kandahar (in the southern section of the city) in the 4th century BC and named it Alexandria Arachosia. Many empires have long fought over the city due to its strategic location along the trade routes of southern, central and western Asia. In 1709, Mirwais Hotak made the region an independent kingdom and made Kandahar the capital of the Hotak dynasty. In 1747, Ahmad Shah Durrani, founder of the Durrani dynasty, made Kandahar the capital of the Afghan Empire.

Loy Kandahar (Pashto: لوی کندهار, pronounced [loɪ 'kand̪(ah)ɑr]; lit. 'Greater Kandahar') is a historical and cultural region of Afghanistan, comprising the modern Afghan provinces of Kandahar, Helmand, Farah, Uruzgan, as well as parts of Nimruz and Zabul, and the Pashtun majority northern part of Balochistan including cities like Quetta, Chaman and many other areas (the latter known as "South Pashtunkhwa"). In 1709, Mirwais Hotak made the region an independent kingdom and turned Kandahar city into the capital of the Hotak dynasty. In 1747, Ahmad Shah Durrani, founder of the Durrani dynasty, made Kandahar the capital of the Afghan Empire.

Loy Kandahar is vaguely defined by a common culture and history that is connected to the local indigenous tribes that reside in the region. Some people may refer to these areas as being under the "Kandahari cultural sphere of influence".Particular styles of clothing, articles of clothing, turban styles, turban cloth colors, dialects of Pashto language, etc. may sometimes be associated with specific tribes indigenous to Loy Kandahar and thus integrate themselves into regional culture. For instance, a Pashtun tribesman from Loy Kandahar may quickly recognize a Pashtun from Loya Paktia based upon his turban style and color. Likewise, a Pashtun from Loya Paktia may recognize someone from Loy Kandahar based upon his unique style of collarless kameez (shirt) with specific embroidered patterns on the front. There are many subtle and intricate cultural indicators of this type that are not recorded in any known written history but simply known and observed by the tribesmen of the various Pashtun regions of Afghanistan and Pakistan.

Kamran Mirza Durrani (Pashto/Persian: کامران میرزا دورانی) was the last Durrani ruler of Herat from 1826 to 1842. He was the son and successor of Mahmud Shah Durrani (r. 1801–1803, 1809–1818). During Kamran Mirza's early life, a lengthy struggle for control of the capital Kabul occurred between his father and his father's half-brother, Shah Shujah Durrani (r. 1804–1809). In this period, Kamran Mirza governed the city of Kandahar, while his uncle Firuz al-Din Mirza ruled Herat under Iranian suzerainty. When Firuz al-Din rebelled in 1814, Kamran Mirza suppressed the revolt.

In 1818, the Durrani minister Fateh Khan Barakzai deposed Firuz al-Din as ruler of Herat; his troops then plundered the city, and his brother Dost Mohammad Khan raped Kamran Mirza's sister. In revenge, Kamran Mirza captured Fateh Khan and had him executed, which prompted a rebellion by Fateh Khan's brothers. This forced Mahmud Shah and Kamran Mirza to retreat to Herat, the last Durrani stronghold. In 1826, Kamran Mirza became the ruler of Herat after defeating his father, who then withdrew from politics. In an attempt to strengthen Iranian control of Herat, the Iranian crown prince Abbas Mirza besieged Herat in 1833. Although Abbas Mirza died during the siege, Kamran Mirza acknowledged Iran's nominal suzerainty. A second siege took place in 1837–1838 under Mohammad Shah Qajar (r. 1834–1848), but British intervention forced the Iranians to withdraw. After the British embassy left Herat, Kamran Mirza renewed his allegiance to Iran in 1841.
