Alp-Tegin

Alp-Tegin, (Persian: الپتگین Alptegīn or Alptigīn) or Alptekin, was a Turkic slave commander general of the Samanid Empire, who would later become the semi-independent governor of Ghazna from 962 until his death in 963.

Before becoming governor of Ghazni, Alp-Tegin was the commander-in-chief (sipahsalar) of the Samanid army in Khorasan. In a political fallout over succession of the Samanids he crossed the Hindu Kush mountains southward and captured Ghazna, located strategically between Kabul and Kandahar in present-day Afghanistan, and thereby establishing his own principality, which, however, was still under Samanid authority. He was succeeded by his son, Abu Ishaq Ibrahim.
