The Qutb Minar , also spelled Qutab or Qutub, is an array of monuments and buildings at Mehrauli in Delhi, India. The construction of Qutb Minar was intended as a Victory Tower, to celebrate the victory of Mohammed Ghori over Rajput king, Prithviraj Chauhan, in 1192 AD, by his then viceroy, Qutb-ud-din Aibak, who later became the first Sultan of Delhi of Mamluk dynasty. After the death of the commissioner, the Minar was added upon by his successor Iltutmish  and much later by Firoz Shah Tughlaq, a Tughlaq dynasty, Sultan of Delhi in 1368 AD. The complex initially housed a complex of twenty-seven ancient Hindu and Jain temples which were destroyed and their material used in the construction of the Quwwat-ul-Islam Mosque next to the Qutb Minar, in the Qutb complex, built on the ruins of Lal Kot Fort built by Tomar Rajput ruler, Anangpal in 739 AD and Qila-Rai-Pithora, Prithviraj Chauhan’s city, the Rajput king, whom Ghori’s Afghan armies had earlier defeated and killed, at the Second Battle of Tarain.
The complex was added to by many subsequent rulers, including Firoz Shah Tughlaq and Ala ud din Khilji as well as the British.Some constructions in the complex are the Qutb Minar, the Quwwat ul-Islam Mosque, the Alai Gate, the Alai Minar, the Iron pillar, and the tombs of Iltutmish, Alauddin Khilji and Imam Zamin; surrounded by Jain temple ruins.In all, Islamic fanatic ruler Qutb-ud-din Aibak destroyed 27 Hindu and jain temples and reused the building materials for construction of Quwwat-ul-Islam mosque and the Qutub Minar according to a Persian inscription still on the inner eastern gateway.
