The Ghaznavid dynasty was a Muslim Turkic dynasty of mamluk origin, ruling from 977 to 1186.  The dynasty was founded by Sabuktigin upon his succession to the rule

of Ghazna after the death of his father-in law, Alp Tigin, who was an ex-general of the Samanid Empire from Balkh, north of the Hindu Kush in Greater Khorasan.

Sebuktigin's son, Mahmud of Ghazni (997-1030), declared independence from the Samanid Empire, and expanded the Ghaznavid Empire to the Amu Darya, the Indus

River and the Indian Ocean in the east and Hamadan in the west.  Under the reign of Mas'ud I (1030-1041), the Ghaznavid dynasty began losing control over its western

territories to the the Seljuq dynasty, resulting in a restriction of its holdings to modern-day Afghanistan and Pakistan.  In 1151, Sultan Bahram Shah (1117-1157) lost

Ghazni to Ghurid king 'Ala al din Husayn.

Ghaznavid struggles with the Ghurids continued in subsequent years as they nibbled away at Ghaznavid territory, and Ghazni and Zabulistan were lost to a group of

Oghuz Turks before being captured by the Ghurids.  Ghazni fell to the Ghurids around 1170.  After the fall of Ghazn, the Ghaznavids established themselves in Lahore,

their regional capital for Indian territories since its conquest by Mahmud of Ghazni, which became the new capital of the Late Ghaznavids.  

Ghaznavid power in northwestern India continued until the Ghurid conquest of Lahore by Muhammad of Ghor in 1186, deposing the last Ghaznavid ruler Malik.  Both

Khusrau Malik and his son were imprisoned and summarily executed in 1191.
