Final answer:
The Sikh temple Harmandir Sahib was not blown up with gunpowder by Ahmed Shah Durrani. The Massacre of Amritsar in 1919, during British rule in India, is mistakenly thought of as the blowing up of Harmandir Sahib.
Step-by-step explanation:
The Sikh temple known as Harmandir Sahib was not blown up by Ahmed Shah Durrani with gunpowder. The incident you are referring to is commonly known as the Massacre of Amritsar, which took place in 1919 during British rule in India. The British army, under the command of General Reginald Dyer, opened fire on a peaceful gathering of Indians protesting against British rule. This tragic event led to widespread condemnation and further fueled the movement for Indian independence.
