Ghurid dynasty

The Ghurid dynasty (also spelled Ghorids; Persian: دودمان غوریان, romanized: Dudmân-e Ğurīyân; self-designation: شنسبانی, Šansabānī) was a Persianate dynasty of presumably eastern Iranian Tajik origin, which ruled from the 8th-century in the region of Ghor, and became an Empire from 1175 to 1215. The Ghurids were centered in the hills of Ghor region in the present-day central Afghanistan, where they initially started out as local chiefs. They gradually converted to Sunni Islam after the conquest of Ghor by the Ghaznavid ruler Mahmud of Ghazni in 1011. The Ghurids eventually overran the Ghaznavids when Muhammad of Ghor seized Lahore and expelled the Ghaznavids from their last stronghold.

The Ghurids initially ruled as vassals of the Ghaznavids and later of the Seljuks. However, during the early twelfth century the long-standing rivalry between the Seljuks and Ghaznavids created a power vacuum in eastern Afghanistan and Panjab which the Ghurids took advantage of and began their territorial expansion. Ala al-Din Husayn ended the Ghurid subordination to the Ghaznavids, ruthlessly sacking their capital, although he was soon defeated by the Seljuks after he stopped paying tribute to them. The Seljuk imperial power, however, was itself swept away in eastern Iran with the contemporaneous advent of the Khwarazmian Empire.

During the dyarchy of Ala al-Din Husayn nephews - Ghiyath al-Din Muhammad and Muhammad of Ghor, the Ghurid empire reached its greatest territorial extent, holding encompassed territory from eastern Iran through easternmost India. While Ghiyath al-Din was occupied with the Ghurid expansion in the west, his junior partner in the dyarchy, Muhammad of Ghor and his lieutenants were active east of the Indus Valley as far as Bengal and eventually succeeded in conquering wide swaths of the Gangetic Plain, while in the west under Ghiyath al-Din, engaging in a protracted duel with the Shahs of Khwarazm, the Ghurids, reached as far as Gorgan (present-day Iran) on the shoreline of the Caspian Sea, albeit for a short time.

Ghiyath al-Din Muhammad died in 1203 of illness caused due to rheumatic disorders and soon after the Ghurids suffered a crushing defeat against the Khwrezmians aided by timely reinforcements from the Qara Khitais in the Battle of Andkhud in 1204. Muhammad was assassinated soon after in March 1206 which ended the Ghurid influence in Khurasan. The dynasty became extinguished all together within a decade when Shah Muhammad II uprooted the Ghurids in 1215. Their conquests in the Indian Subcontinent nevertheless survived for several centuries under the evolving Delhi Sultanate established by Qutb ud-Din Aibak.
