Explanation: The history of Delhi as a capital city is rich and complex, with numerous dynasties ruling over the region. The Tomaras were the first to establish a significant presence in Delhi, making them the earliest known rulers of the city. The Tomaras were a Rajput dynasty that ruled from the 8th to the 11th century. They established their capital at the site of present-day Delhi, which was then known as Dhillika or Lal Kot. The Tomaras were known for their fortifications and the construction of Lal Kot, which laid the foundation for the city's future development.
The Chauhans, another Rajput dynasty, succeeded the Tomaras in the 12th century. They expanded the city and built Qila Rai Pithora, which further fortified the region. The Chauhans were followed by the Turkish rulers, who established the Delhi Sultanate in the 12th century. The Delhi Sultanate was a period of significant Islamic rule in India, with various dynasties such as the Mamluks, Khaljis, Tughluqs, Sayyids, and Lodis ruling over Delhi.
The Tughluq Dynasty, mentioned in the options, was one of the later dynasties of the Delhi Sultanate. They came to power in the 14th century and were known for their extensive administrative reforms and the construction of the city of Tughluqabad. However, they were not the first to rule Delhi.
Understanding the chronology of Delhi's rulers is essential for comprehending the historical development of the city. The Tomaras, as the first dynasty to rule Delhi, played a crucial role in establishing the city's significance as a capital. Their rule laid the foundation for the subsequent dynasties that would come to power in Delhi, each contributing to the city's rich and diverse history.
In summary, the Tomaras were the first dynasty to rule Delhi, establishing their capital at the site of present-day Delhi. This makes them the correct answer to the question of which dynasty was the first to rule Delhi. The other options, while significant in their own right, came to power after the Tomaras and thus do not fit the criteria of being the first rulers of Delhi.
