Explanation: Juna Khan, also known as Qutb ud din Aibak, was a significant figure in the history of the Delhi Sultanate. He was originally a slave of Muhammad Ghori, the ruler of the Ghurid Empire, and was appointed as the governor of Delhi after Ghori's death. Juna Khan played a crucial role in consolidating the Ghurid Empire's control over northern India and was responsible for the establishment of the Delhi Sultanate.
The Delhi Sultanate was the first Muslim sultanate in the Indian subcontinent, and its establishment marked a significant shift in the political landscape of medieval India. Juna Khan's victory over the Ghurid Empire and his subsequent rule over Delhi were pivotal in this transition. He was given a hero's welcome by the jubilant Sultan in Delhi, which symbolized the beginning of a new era of Muslim rule in India.
Juna Khan's reign was short-lived, but his legacy was significant. He laid the foundation for the Delhi Sultanate, which would go on to rule large parts of India for several centuries. His rule was characterized by the construction of important architectural landmarks, such as the Quwwat-ul-Islam mosque and the Qutb Minar, which are still standing today and are considered important historical monuments.
It is important to note that the other options provided in the question do not pertain to the historical context of the Delhi Sultanate's establishment. Shams ud din, Rukn ud din, and Bahadur Shah were all rulers of the Delhi Sultanate or the Mughal Empire but were not associated with the initial establishment of the Sultanate. Therefore, Juna Khan is the correct answer as he was the first Sultan of the Delhi Sultanate and was given a hero's welcome by the jubilant Sultan in Delhi.
Understanding the historical context of the Delhi Sultanate and the role of Juna Khan is crucial for comprehending the political and cultural changes that occurred in medieval India. This knowledge is essential for students studying Indian history and for those preparing for competitive examinations that cover this period of Indian history.
