Delhi’s ups and downs in the history has seen establishment of seven cities at different times by different Rulers. In the known history, the first city of Lal Kot was constructed by King Anang Pal of Tomar Dynasty in 11th century. Prithvi Raj Chauhan III (1170-92AD), also known as Rai Pithora built “Qila Rai Pithora” as an extended part of Lal Kot. Qutub Complex is situated in that old city. This first city was conquered by Mohd. Ghori in 1192 AD and placed Qutubuddin Aibak as his Viceroy. Although with the passage of time several cities rose to prominence but were soon lost in oblivion. Cities like Siri, Tughalakabad, Jahapanh, Firozabad, Dinapanah, and Shajanabad were inhabited and deserted but Qutub Complex never lost its importance during the 664 years of Muslim Rule in India.
Qutub Minar is now the Logo of Delhi city. It was here that the Qutubuddin Aibak, Iltutmish and Balban, who were mere slaves rose to the highest position of the Sulatans of the country. This place was also a mute witness of soaring ambitions, untiring struggles, indefatigable energy and finally occupation of the highest position in the country. It was in Lalkot that Razia, the first lady Sultan of India occupied the throne defying the current political, social and religious customs.
The Delhi Sultans especially Qutubuddin Aibak, Iltutmish and Alauddin Khilji were responsible for most of the monuments at Qutub Complex. The significant monuments are
· Qutub Minar,
· Quwwatul Islam Mosque,
· Alai Darwaza,
· Tomb of Iltutmish,
· Tomb of Alauddin Khilji
· Alai Minar and
· Iron Pillar.
· Tomb of Imam Zamin
Earliest of these Islamic structures incorporate many Hindu elements due to the ready availability of building material and local craftsmen.
