The history of Delhi can be traced back to Mahabharat times where Pandava built a highly fortified city named as a Indraprastha to rule the country. Then after a long silence, Delhi again came into prominence in the thirteen century when Prithvi Raj Chauhan became the king. He made Delhi as his state capital and renamed it Rai Qila Pithora which was earlier ruled by Tomara ruler Anangpal as a Lal Kot. Now, the splendour and royalty of Delhi reached far and wide. Impressed by aristocracy of Delhi, Muhammad Ghori decided to invade it.
In the second battle of Tarain, he was finally succeeded to defeat Prithvi Raj Chauhan and appointed his slave Qutubuddin Aibak as the governor of Delhi. He made Mehrauli his capital. Slave dynasty ruled the Hindu populace just about hundred years when Khilji dynasty took the reign of Delhi. The most powerful and second ruler of Khilji dynasty, Ala-uddin-Khilji erected Siri as his capital to rule the country.
After the death of Alauddin Khilji, there was no potent ruler to sustain and keep the anarchy at bay. Finding the opportunity, Ghiyasuddin Tughluq rose into prominence, decimated the last ruler of Khilji dynasty and became the king. He laid the foundation of Tughluqabad as a capital city. He was succeeded by his son Muhammad Bin Tughluq, the most brilliant ruler of Delhi sultanate, who made Jahanpanah rule the roost. He was succeeded by his cousin Feroz Shah Tughluq who added the fifth story in Qutub-Minar and made Ferozabad as his capital to carry the honour and dignity of Tughluq dynasty forward.
In the sixteen century, Delhi came under the hegemony of Mughals. Humayun made Dinpanah as his capital and his rival Shershah Suri- shergarh. Both capitals are said to be considered on the legendary site of Indraprastha. The majestic and glory of Delhi reached its climax when Mughal Emperor Shah-jahan built the walled city which was known as Shahjahanabad contained Red Fort and Chandini Chowk and presently it is called Old Delhi.
Finally, Britishers shifted their capital from calcutta to Delhi in 1912 with a notion that they would rekindle the splendour and glory of Great Mughal Emperors. And the second reason for making Delhi as their capital was that it was reckoned to be safe place to rule because Bengal at that time became the Pandora box for them. Lutyen became the architect of Delhi that is why it is also called Lutyens’ Delhi or New Delhi. Now, New Delhi is the capital of modern India.
