Who returned the 'Knighthood' title to the British Government in reaction against Jalianwala Bagh Massacre ?

Rabindranath Tagore renounced his Knighthood in May 1919 as a direct protest against the Jallianwala Bagh Massacre (April 13, 1919). He had been awarded the title by the British in 1915. In a powerful letter to the Viceroy, Lord Chelmsford, Tagore stated that the "time has come when badges of honour make our shame glaring in the incongruous context of humiliation."

Other significant reactions included:

• Shankaran Nair resigned from the Viceroy’s Executive Council in protest against the atrocities in Punjab.
• Mahatma Gandhi returned the Kaisar-i-Hind gold medal in 1920 during the launch of the Non-Cooperation Movement.

The massacre, where troops under General Dyer fired on an unarmed crowd in Amritsar, served as a catalyst for the Indian National Movement, shifting the focus toward a demand for complete independence.
