Most historians believe that the pillar was not originally erected in Delhi. Instead, it is thought to have stood at an ancient Vishnu temple, possibly located in Udayagiri (Madhya Pradesh) or another important Gupta religious site.
According to the most widely accepted theory, the pillar was transported to Delhi during the reign of King Anangpal Tomar, the founder of the Tomar dynasty, around the 11th century CE. The Tomars established one of the earliest fortified cities in Delhi, known as Lal Kot.
Although some historical debates continue regarding its original location, King Anangpal Tomar is commonly credited with relocating the pillar to the Delhi region, where it later became part of the Qutub Minar Complex after the establishment of the Delhi Sultanate.
Mehrauli Iron Pillar Inscription Tells About Which King?
The search query "Mehrauli Iron Pillar inscription tells about which king" is extremely popular among students and history enthusiasts.
The inscription engraved on the pillar praises a king named "Chandra". Most historians identify this ruler as Emperor Chandragupta II Vikramaditya of the Gupta Empire.
The inscription describes him as a courageous and victorious ruler who conquered many kingdoms and protected his people. It also highlights his devotion to Lord Vishnu, explaining why the pillar was originally erected as a religious monument.
Although a few scholars have proposed alternative identifications, the overwhelming academic consensus supports Chandragupta II as the king mentioned in the inscription.
The Sanskrit Inscription Explained
The Mehrauli Iron Pillar inscription is one of the most valuable historical records from the Gupta period. It is written in elegant Sanskrit using the ancient Brahmi script.
