Why Rabindranath Tagore surrendered his title to British?
Due to Jallianwala Bagh massacre (happened in 13th April 1919) incident, Rabindranath Tagore surrendered his title to British.
Rabindranath Tagore got Knighthood from King George-V in 1915 for his contribution to literature. Later in 1919, he renounced knighthood for the inhuman act of British in Jallianwala Bagh. Due to same reason Gandhi returned the Kaiser-i-Hind Gold medal given to him by British government for his work during Boer war.
