Qutb ud-Din Aibak ( Persian: قطب‌الدین ایبک ), (1150 – 14 November 1210) was a Turkic general of the Ghurid emperor Muhammad Ghori. He was in charge of the Ghurid territories in northern India, and after Muhammad Ghori's assassination in 1206, he established the Delhi Sultanate (1206–1526), and started the Mamluk dynasty.

Quwwat-ul-Islam Mosque, to the north-east of the Minar was built by Qutub-ud-Din Aibak in A.D. 1199. It is the earliest extant - mosque built by the Delhi Sultans. It consists of a rectangular courtyard enclosed by cloisters, erected with the carved columns and architectural members of 27 Jain and Hindu temples, which were demolished by Qutub.

Quṭb al-Dīn Aibak, Aibak also spelled Aybak, (born 1150 —died 1210), a founder of Muslim rule in India and an able general of Muʿizz al-Dīn Muḥammad ibn Sām of Ghūr. In childhood Quṭb was sold as a slave and raised at Nishapur. He came into the possession of Muʿizz al-Dīn, who put him in charge of the royal stables. Eventually he was appointed to military command, and in 1193.

Qutb-ud-din Aibak began constructing the Quwwat-ul-Islam mosque, one of Delhi’s first Muslims, but he remained unable to complete it. Shamsuddin Iltutmish, his successor, completed these architectures later. He also started the construction of “Qutb Minar in 1199 ” in Quwwat-ul-mosque which has a height near 72.5 meters.
