Qutb al-Din Aibak aka Aibak was the first sultan who founded Delhi as Capital of Sultanate. He was a slave of Muhammad of Ghor, who made him the Amir-i-Akhur (the Master of Slave). Aibak was appointed to military command and became an able general of Muhammad of Ghor. In 1193 and after conquering Delhi, his master returned to Khorāsān and left the consolidation of the Ghūrid conquests in northwest India to him.
