Qutb-Ud-Din Aibak was the founder of Slave Dynasty of medieval India. He was the first Sultan of Delhi who ruled for only four years, from 1206to 1210.

Qutb-Ud-Din Aibak was Turkic descent who born in the central Asia. When he was a child, he was sold in a slave market (mamluk). The chief Qazi of Nishapur, a small town in the province of Khorasan in northeastern Iran brought Qutb-Ud-Din Aybak. He was very kind to the boy, treated him like one of his sons and gave him good education along with training in archery and horse riding. But his master`s sons were jealous of Qutb-Ud-Din Aibak and sold him to a slave merchant as soon as his master, the old Qazi died. Sultan Muhammad Ghori, ruler of Ghor in northwestern Afganistan purchased Qutb-Ud-Din Aybak.

Sultan Ghori was of Aimak origin who was a great conqueror and established his control over present-day Afghanistan, Tajikistan, Turkestan, Pakistan and northern India including sacking of Delhi in 1193. Sultan Ghori was the founder of first confirmable Muslim administration that established its identity through collection of state taxes, establishing the rule of law, fair distribution of lands, application of revenues to the nobles under his charge etc. A government that was established on the locally elected representation through Mashura courts and nominated administrators was another characteristic property. Qutb-Ud-Din Aibak rose to high rank under the service of Sultan Ghori and became his most trusted general. He got his greatest military success under Sultan Ghori`s guidance and leadership. Qutb-Ud-Din Aibak was the person who executed and consolidated Sultan Ghori`s conquest in northern India. Sultan Ghori left Qutb-Ud-Din Aibak with the independent charge of newly conquered land of Indian territory and could demand the levies from the areas in India that were under Ghori`s subjection because after 1192 Sultan Ghori put his concentration on Central Asia.

Qutb-Ud-Din Aibak set up the first Muslim state in north India. Mohammed Ghori died in 1206 and Qutb-Ud-Din Aibak had to undergo a brief struggle for power. He succeeded in establishing himself as a ruler of Afganistan, Pakistan and Northern India.

Qutb-Ud-Din Aibak is considered as the first Muslim ruler of south Asia. The areas on which he executed his power were those over which Sultan Ghori already took possession through the exaction of levies by the local receiver general. Thereby Qutb-Ud-Din Aibak could consolidate his administration though his tenure of ruling was only for four years, as it was already established by his predecessor. Even he could achieve it despite of the opposition of the nobles like Taj-Ud -Din Ildiz and Nasir-Ud-Din Qibachah. Initially Qutb-Ud-Din Aybak controlled his reign from Lahore but later shifted his capital to Delhi.

Qutb-Ud-Din Aibak built up Delhi`s earliest Muslim monument. The Quwwat-ul- Islam Mosque and the Qurtab Minar. Muslim historian Maulana Hakim Saiyid Abdul Hai described Qutb-Ud-Din Aibak as an iconoclast. Qubbat al-Islam was the first mosque built in Delhi, which was established after demolishing the Hindu temple built previously by Prithvi Raj. This can be proved as certain parts of the mosque still carries the original structure of the temple. This pattern of iconoclasm was very common at that time. The Qutab Minar started at his reign but was completed by his successor Iltutmish Aybak, who was also known as Lakh Baksh(giver of hundred thousands) due to his generosity. Qutb-Ud-Din Aybak was a pious Muslim, who was praised by other devoted Muslims. He patronized Nizami and Fakh-I-Mudabbir and both of them dedicated their works to Aybak.

Qutb-Ud-Din Aibak prematurely died in an accident in 1210. While he was playing polo(Chougan) on horseback, his horse suddenly fell and Qutb-Ud-Din Aibak was spiked on a pommel of his saddle. Qutb-Ud-Din Aybak was buried near the Anarkali bazaar of Lahore. Qutab-ud-din Aibak`s tomb is located at Lahore. His successor was Shams-Ud-Din Iltutmish, who was his slave as well as his son in law.
