Bishnu Prasad Rabha (1909–1969) was a legendary cultural icon of Assam — a revolutionary, poet, playwright, musician, painter, and freedom fighter. Known as “Kalaguru” (Master of the Arts), he played a vital role in the cultural and political awakening of Assam in the 20th century. Born on January 31, 1909, in Dacca (now Dhaka, Bangladesh), his family later settled in Tezpur, Assam. A brilliant student and a gifted artist, Rabha used his talents to inspire the masses, especially the oppressed and working classes. He was deeply involved in the Indian freedom struggle, aligning himself with leftist ideologies and joining the Revolutionary Communist movement. Bishnu Prasad Rabha’s contributions extended beyond art — he donated vast portions of his land for the welfare of indigenous people. He passed away on June 20, 1969, but remains a towering figure in Assam’s history. His birth anniversary is celebrated as Kalaguru Divas, and he is remembered as a true people's artist who blended art with activism.
