In which of the following years did Nadir Shah invade India and sack Delhi?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e.1739.
Nadir Shah invaded India and sacked Delhi in 1739. After his decisive victory over the Mughal army at the Battle of Karnal in February 1739, he marched to Delhi and entered the city in March. The ensuing occupation led to a widespread massacre and immense plunder, including the legendary Peacock Throne and the Koh-i-Noor diamond, severely weakening the already declining Mughal Empire.
