Explanations:The Delhi Sultanate was a significant Islamic empire that ruled large parts of the Indian subcontinent from the early 13th to the early 16th century. The Qutub Minar, a prominent landmark in Delhi, was initiated by Qutub-ud-din Aibak, the first ruler of the Delhi Sultanate, but it was Iltutmish who completed its construction. The Qutub Minar is a minaret and victory tower, standing at 73 meters tall, and is one of the tallest brick minarets in the world. It is a symbol of the Delhi Sultanate's architectural and cultural achievements.
Iltutmish, who ruled from 1211 to 1236, was a powerful and influential ruler of the Delhi Sultanate. He not only completed the Qutub Minar but also played a crucial role in defending the Sultanate from the Mongol invasions led by Chengiz Khan. The Mongol Empire, under Chengiz Khan, was expanding rapidly across Central Asia and posed a significant threat to the Delhi Sultanate. Iltutmish successfully repelled the Mongol invasions, thereby saving the Delhi Sultanate from potential destruction.
Understanding the historical context of the Delhi Sultanate and the contributions of its rulers is essential for comprehending the political and cultural landscape of medieval India. Iltutmish's reign was marked by significant administrative reforms, military victories, and architectural achievements, making him a pivotal figure in the history of the Delhi Sultanate.
It is important to distinguish between the contributions of different rulers of the Delhi Sultanate. While Qutub-ud-din Aibak initiated the construction of the Qutub Minar, it was Iltutmish who completed it. Similarly, while other rulers like Ghiyas-ud-din Balban also made significant contributions to the Delhi Sultanate, they were not involved in the completion of the Qutub Minar or the initial defense against the Mongols.
Thus, Iltutmish's role in completing the Qutub Minar and defending the Delhi Sultanate from the Mongol invasions makes him the correct answer to this question. Understanding these historical events and the contributions of individual rulers is crucial for a comprehensive understanding of the Delhi Sultanate and its impact on Indian history.
