Ghurid dynasty
The Ghurid dynasty was a culturally Persianate dynasty of 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 the 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 12th-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 the 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 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.
Origins
In the 19th century some European scholars, such as Mountstuart Elphinstone, favoured the idea that the Ghurid dynasty was related to today's Pashtun people but this is generally rejected by modern scholarship. Contemporary scholars state that the dynasty was of Tajik origin. Later, due to intermarrying, the Ghurid princes were distinguished by their significant blending of Tajik, Persian, Turkic, and native Afghan ethnicities.Encyclopædia Iranica states: "Nor do we know anything about the ethnic stock of the Ḡūrīs in general and the Šansabānīs in particular; we can only assume that they were eastern Iranian Tajiks". Bosworth further points out that the actual name of the Ghurid family, Āl-e Šansab, is the Arabic pronunciation of the originally Middle Persian name Wišnasp.

Historian André Wink explains in The New Cambridge History of Islam:
When the Ghurids started to distinguish themselves through their conquests, courtiers and genealogists forged a fictive genealogy which connected the Ghurids with the Iranian past. They traced the Ghurid family back to the mythical Arab tyrant Zahhak, mentioned in the medieval Persian epic Shahnameh, whose family had reportedly settled in Ghur after the Iranian hero Fereydun had ended Zahhak's thousand-year tyranny.
Additionally, nothing is known of the pre-Islamic religious beliefs of the Ghurids.
Language
The Ghurids' native language was apparently different from their court language, Persian. Abu'l-Fadl Bayhaqi, the famous historian of the Ghaznavid era, wrote on page 117 in his book Tarikh-i Bayhaqi: "Sultan Mas'ud I of Ghazni left for Ghoristan and sent his learned companion with two people from Ghor as interpreters between this person and the people of that region." However, like the Samanids and Ghaznavids, the Ghurids were great patrons of Persian literature, poetry, and culture, and promoted these in their courts as their own. Modern-day authors refer to them as the "Persianized Ghurids". Wink describes the tongue of the Ghurids as a "distinct Persian dialect".There is nothing to confirm the recent conclusion that the inhabitants of Ghor were originally Pashto-speaking, and claims of the existence of "Pashto poetry", such as Pata Khazana, from the Ghurid period are unsubstantiated.
Extent
In the west, Ghurid territory extended to Nishapur and Merv, while Ghurid troops reached as far as Gorgan on the shores of the Caspian Sea. Eastward, the Ghurids invaded as far as Bengal.History
Early history
A certain Ghurid prince named Amir Banji was the ruler of Ghor and ancestor of the medieval Ghurid rulers. His rule was legitimized by the Abbasid caliph Harun al-Rashid.Before the mid-12th century, the Ghurids had been bound to the Ghaznavids and Seljuks for about 150 years. Beginning in the mid-12th century, Ghor expressed its independence from the Ghaznavid Empire. The early Ghurids followed Paganism before being converted to Islam by Abu Ali ibn Muhammad. In 1149 the Ghaznavid ruler Bahram-Shah of Ghazna poisoned a local Ghurid leader, Qutb al-Din Muhammad, who had taken refuge in the city of Ghazni after having a quarrel with his brother Sayf al-Din Suri. In revenge, Sayf marched towards Ghazni and defeated Bahram-Shah. However, one year later, Bahram returned and scored a decisive victory against Sayf, who was shortly captured and crucified at Pul-i Yak Taq. Baha al-Din Sam I, another brother of Sayf, set out to avenge the death of his two brothers, but died of natural causes before he could reach Ghazni.
Ala al-Din Husayn, one of the youngest of Sayf's brothers and newly crowned Ghurid king, also set out to avenge the death of his two brothers. He managed to defeat Bahram-Shah, and then had Ghazni sacked; the city burned for seven days and seven nights. He also sacked the Ghaznavid fortresses and palaces of Bost. These actions earned him the title of Jahānsūz, meaning "the world burner". The Ghaznavids retook the city with Seljuq help, but later lost it to Oghuz Turks.
In 1152, Ala al-Din Husayn refused to pay tribute to the Seljuks and instead marched an army from Firozkoh but was defeated and captured at Nab in the Harīrūd Valley by Sultan Ahmed Sanjar after his forces defected to the Seljuqs. During the battle, 6000 nomads from Ala al-Din's forces went over to the Seljuk army. Despite relatively smaller size of both armies, the defection of nomads at critical point of the battle eventually decided the issue in favour of the Seljuks. Ala al-Din Husayn remained a prisoner for two years, until he was released in return for a heavy ransom to the Seljuqs and was allowed to reclaim his principality in Ghor. However, Sanjar was soon captured and imprisoned by the Ghuzz nomads in 1153, which allowed the Ghurids to expand their polity again. Meanwhile, a rival of Ala al-Din named Husayn ibn Nasir al-Din Muhammad al-Madini had seized Firozkoh, but was murdered at the right moment when Ala al-Din returned to reclaim his ancestral domain. Ala al-Din spent the rest of his reign expanding the domains of his kingdom; he managed to conquer Garchistan, Tukharistan, Zamindawar, Bust, Bamiyan and other parts of Khurasan. Ala al-Din died in 1161, and was succeeded by his son Sayf al-Din Muhammad, who died two years later in a battle against the Oghuz Turks of Balkh.
During the reign of Ala ad-Din, the Ghurids firmly established themselves at Firuzkuh and made it their capital, at the same time, the minor branches of the family who were the offshoot of concubinage with Turkish slave girls whom chronicler Juzjani called "Kanizak-i-turki" established themselves in Bamiyan and elsewhere.
The Ghurids at their zenith
Sayf al-Din Muhammad was succeeded by his cousin Ghiyath al-Din Muhammad, who was the son of Baha al-Din Sam I, and proved himself to be a capable king. Right after Ghiyath's ascension, he, with the aid of his loyal brother Muhammad of Ghor, killed a rival Ghurid chief named Abu'l Abbas. Ghiyath then defeated his uncle Fakhr al-Din Masud who claimed the Ghurid throne and had allied with the Seljuq governor of Herat and Balkh.In 1173, Muhammad of Ghor after multiple attempts reconquered the city of Ghazni from the Ghuzz Turks, who had deposed the Ghaznavids from there earlier. In 1175, the Ghurids took control of Herat from the Seljuks, and the city became one of their main power bases and centers of cultural development, together with Firozkoh and Ghazni. They also took control of the areas of Nīmrūz and Sīstān, and extended their suzerainty as far as the Seljuks of Kerman.
Ghurid conquest of Khorasan
Afterwards, Muhammad assisted his brother Ghiyath in his contest with the Khwarezmian Empire, who were at times supported by their "pagan" suzerains the Qara Khitai, for the lordship of Khorasan. Seljuk power in Khorasan had collapsed since the defeat of Ahmad Sanjar against the Ghuzz Turks in 1153, which left the region at the hands of the Turkmen. In 1181, Sultan Shah, a pretendent to the Khwarezmian throne, managed to take control of Khorasan, until 1192 when he was defeated near Merv by the Ghurids, who captured his territories. The Ghurids then took control of all Khorasan following the death of his successor Tekish in 1200, capturing Nishapur in 1200, and reaching as far as Besṭām in the ancient region of Qūmes.After the death of his brother Ghiyath on 13 March 1203, Muhammad became the successor of his empire and ruled until his assassination in 1206 near Jhelum by Ismāʿīlīs whom he persecuted during his lifetime.
