The first Muslim dynasties

Islamic armies defeated the Sāsānids in 642 at the Battle of Nahāvand (near modern Hamadān, Iran) and advanced into the Afghan area, but they were unable to hold the territory; cities submitted, only to rise in revolt, and the hastily converted returned to their old beliefs once the armies had passed. The 9th and 10th centuries witnessed the rise of numerous local Islamic dynasties. One of the earliest was the Ṭāhirids of Khorāsān, whose kingdom included Balkh and Herāt; they established virtual independence from the ʿAbbāsid Caliphate in 820. The Ṭāhirids were succeeded in 867–869 by a native dynasty from Sīstān, the Ṣaffārids. Local princes in the north soon became feudatories of the powerful Sāmānids, who ruled from Bukhara. From 872 to 999 Bukhara, Samarkand, and Balkh enjoyed a golden age under Sāmānid rule.

In the middle of the 10th century a former Turkish slave named Alptigin seized Ghazna. He was succeeded by another former slave, Subüktigin, who extended the conquests to Kabul and the Indus. His son was the great Maḥmūd of Ghazna, who came to the throne in 998. Maḥmūd conquered the Punjab and Multan and carried his raids into the heart of India. The hitherto obscure town of Ghazna became a splendid city, as did the second capital at Bust (Lashkar Gāh).

Maḥmūd’s descendants continued to rule over a gradually diminishing empire until 1150, when ʿAlāʾ al-Dīn Ḥusayn of Ghūr, a mountain-locked region in central Afghanistan, sacked Ghazna and drove the last Ghaznavid into India. ʿAlāʾ al-Dīn’s nephew, Muʿizz al-Dīn Muḥammad, known as Muḥammad of Ghūr, first invaded India in 1175. After his death in 1206, his general, Quṭb al-Dīn Aybak, became the sultan of Delhi.

Shortly after Muḥammad of Ghūr’s death, the Ghurīd empire fell apart, and Afghanistan was occupied by Sultan ʿAlāʾ al-Dīn Muḥammad, the Khwārezm-Shah. The territories of the Khwārezm-Shah dynasty extended from Chinese Turkistan in the east to the borders of Iraq in the west.

The Mongol invasion

Genghis Khan invaded the eastern part of ʿAlāʾ al-Dīn’s empire in 1219. Avoiding a battle, ʿAlāʾ al-Dīn retreated to a small island in the Caspian Sea, where he died in 1220. Soon after ʿAlāʾ al-Dīn’s death, his energetic son Jalāl al-Dīn Mingburnu rallied the Afghan highlanders at Parwan (modern Jabal os Sarāj), near Kabul, and inflicted a crushing defeat on the Mongols under Kutikonian. Genghis Khan, who was then at Herāt, hastened to avenge the defeat and laid siege to Bamiyan. There Ṃutugen, the khan’s grandson, was killed, an event so infuriating to Genghis Khan that when he captured the citadel he ordered that no living being be spared. Bamiyan was utterly destroyed. Advancing on Ghazna, Genghis won a great victory over Jalāl al-Dīn, who then fell back toward the Indus (1221), where he made a final but unsuccessful stand.

Later dynasties

After Genghis Khan’s death in 1227, his vast empire fell to pieces. In Afghanistan some local chiefs succeeded in establishing independent principalities, and others acknowledged Mongol princes as suzerains. This state of affairs continued until the end of the 14th century, when Timur (Tamerlane) conquered a large part of the country.

Timur’s successors, the Timurids (1405–1507), were great patrons of learning and the arts who enriched their capital city of Herāt with fine buildings. Under their rule Afghanistan enjoyed peace and prosperity.

Early in the 16th century the Turkic Uzbeks rose to power in Central Asia under Muḥammad Shaybānī, who took Herāt in 1507. In late 1510 the Ṣafavid shah Ismāʿīl I besieged Shaybānī in Merv and killed him. Bābur, a descendant of Genghis Khan and Timur, had made Kabul the capital of an independent principality in 1504. He captured Kandahār in 1522, and in 1526 he marched on Delhi. He defeated Ibrāhīm, the last of the Lodī Afghan kings of India, and established the Mughal Empire, which lasted until the middle of the 19th century and included all of eastern Afghanistan south of the Hindu Kush. The capital was at Agra. Nine years after his death in 1530, the body of Bābur was taken to Kabul for burial.

During the next 200 years Afghanistan was parceled between the Mughals of India and the Ṣafavids of Persia—the former holding Kabul north to the southern foothills of the Hindu Kush and the latter, Herāt and Farāh. Kandahār was in dispute for many years.

Overthrow of foreign rule

Periodic attempts were made to gain independence. In 1709 Mīr Vays Khan, a leader of the Hotaki Ghilzay tribe, led a successful rising against Gorgīn Khan, the Persian governor of Kandahār.

The Durrānī dynasty

The commander of Nādir Shah’s 4,000-man Afghan bodyguard was Aḥmad Khan Abdālī, who returned to Kandahār and was elected shah by a tribal council. He adopted the title Durr-i Durrān (“Pearl of Pearls”). Supported by most tribal leaders, Aḥmad Shah Durrānī extended Afghan control from Meshed to Kashmir and Delhi, from the Amu Darya to the Arabian Sea. The Durrānī was the second greatest Muslim empire in the second half of the 18th century, surpassed in size only by the Ottoman.

Aḥmad Shah died in 1772 and was succeeded by his son, Tīmūr Shah, who received but nominal homage from the tribal chieftains. Much of his reign was spent in quelling their rebellions. Because of this opposition, Tīmūr shifted his capital from Kandahār to Kabul in 1776.

The rise of the Bārakzay

The Bārakzay were now dominant. This situation incited the jealousy of Kāmrān, Maḥmūd’s eldest son, who seized and blinded Fatḥ Khan. Later Shah Maḥmūd had him cut to pieces.
