Which of the following events did NOT occur in 1919?

Partition of Bengal took place

The correct answer is Option 4- Partition of Bengal took place

The Partition of Bengal took place in 1905, not in 1919.

The other three events did occur in 1919:

• The Montague-Chelmsford Reforms were announced in August 1919. These reforms were a step towards self-government for India, and they led to the establishment of the first Indian Legislative Assembly in 1921.
• The Jallianwala Bagh tragedy took place on April 13, 1919. British troops fired on a peaceful crowd of unarmed Indians in Amritsar, killing hundreds of people.
• The Rowlatt Act was passed in March 1919. This act gave the British government sweeping powers to detain and prosecute people without trial.
