Iron pillar of Delhi in the context of Anangpal Tomar

Chandragupta II (r.c. 375–415), also known by his title Vikramaditya, as well as Chandragupta Vikramaditya, was an emperor of the Gupta Empire. Modern scholars generally identify him with King Chandra of the Delhi iron pillar inscription.

He continued the expansionist policy of his father Samudragupta through military conquests and marital alliances. Historical evidence attests to his remarkable victories, which include the defeat of the Sassanids, the conquest of the Western Kshatrapas and the vassalization of the Hunas. Under the reign of Chandragupta II, the Gupta Empire reached its zenith, directly controlling a vast territory which stretched from the Oxus River in the west to the Bengal region in the east, and from the foothills of the Himalayas in the north to the Narmada River in the south. Chandragupta II expanded his influence and indirectly ruled over the Kuntala region of Karnataka through a marriage alliance with Kadambas, and during his daughter Prabhavatigupta's 20-year-long regency, he effectively integrated the Vakataka kingdom into the Gupta Empire.

The Qutb Minar complex are monuments and buildings from the Delhi Sultanate at Mehrauli in Delhi, India. Construction of the Qutub Minar "victory tower" in the complex, named after the religious figure Sufi Saint Khwaja Qutbuddin Bakhtiar Kaki, was begun by Qutb-ud-din Aibak, who later became the first Sultan of Delhi of the Mamluk dynasty (Gulam Vansh). It was continued by his successor Iltutmish (a.k.a. Altamash), and finally completed much later by Firoz Shah Tughlaq, a Sultan of Delhi from the Tughlaq dynasty (1320–1412) in 1368 AD. The Qubbat-ul-Islam Mosque (Dome of Islam), later corrupted into Quwwat-ul Islam, stands next to the Qutb Minar.

Many subsequent rulers, including the Tughlaqs, Alauddin Khalji and the British added structures to the complex. Apart from the Qutb Minar and the Quwwat ul-Islam Mosque, other structures in the complex include the Alai Darwaza gate, the Alai Minar and the Iron pillar.Inside the complex lie the tombs of Iltutmish, Alauddin Khalji and Imam Zamin.
