Famous as the first Red Fort of Delhi, Lal Kot in Delhi was built by the Tomar ruler, king Anangpal. It was built as his citadel around 1050 A.D. According to some historians, Lal Kot in Delhi is built by Anangpal I in 731 AD
Old Delhi or Purani Dilli was founded as a walled city of Delhi, India, founded as Shahjahanabad in 1639, when Shah Jahan, the Mughal emperor at the time, decided to shift the Mughalcapital from Agra.
The founder of the Suri Dynasty, Sher Shah Suri, defeated Humayun in 1540, naming the fort Shergarh; he added several more structures in the complex during his five-year reign. Purana Qila and its environs flourished as the "sixth city of Delhi".
The Khilji sultan laughed at his slave and suggested that the slave build a fort there when he became a sultan. When Ghazi Malik, as Ghiyas-ud-din Tughlaq, founded the Tughlaq Dynastyin 1321, he did just that—Tughlaqabad is Delhi's most colossal and awesome fort, even in its ruined state
