Four years later, Nehru married Kamala Kaul; their only child, Indira Priyadarshini, was born in 1917. A family of high achievers, one of Nehru's sisters, Vijaya Lakshmi Pandit, later became the first woman president of the UN General Assembly.

In 1919, while traveling on a train, Nehru overheard British Brigadier-General Reginald Dyer gloating over the Jallianwala Bagh massacre in which 379 people were killed and at least 1,200 wounded.
