Explanation: The devastation of Delhi in 1739 by Nadir Shah, the ruler of Iran, is a significant event in the history of the Mughal Empire and the city of Delhi. To understand this event, it is essential to delve into the historical context and the specific city that was affected.
Shahjanabad, also known as the Old City of Delhi, was established by Emperor Shah Jahan in 1639 as the capital of the Mughal Empire. It was a grand city with numerous architectural marvels, including the Red Fort, Jama Masjid, and numerous palaces and gardens. Shahjanabad was the center of political power and cultural life in the Mughal Empire until the mid-19th century.
In 1739, Nadir Shah, the ruler of Iran, invaded Delhi. This invasion was part of a larger campaign to expand his empire and gain control over the rich resources of the Mughal Empire. The invasion was particularly devastating for Shahjanabad. Contemporary accounts describe the city as being turned to rubble, with many of its buildings and monuments looted and destroyed. The invasion led to widespread destruction and a significant loss of life, marking a turning point in the history of the Mughal Empire.
The other options provided in the question are incorrect for the following reasons:
- Agra, while historically significant as the site of the Taj Mahal and a former Mughal capital, was not the city described as being turned to rubble by contemporary observers in 1739. The invasion by Nadir Shah specifically targeted Delhi, not Agra.
- Fatehpur Sikri, another historical city associated with the Mughal Empire, was not the target of Nadir Shah's invasion. It had already been abandoned as a capital by the time of the invasion in 1739.
- Karachi, a city in modern-day Pakistan, was not part of the Mughal Empire in the 18th century. The invasion by Nadir Shah was focused on Delhi, not Karachi.
In conclusion, the devastation described by contemporary observers in 1739 refers to Shahjanabad, the capital of the Mughal Empire at the time, which was significantly affected by Nadir Shah's invasion. This event highlights the vulnerability of the Mughal Empire and the impact of external invasions on the city's architecture and cultural heritage.
