Birsa Munda Jayanti is observed in the Indian state of West Bengal every November 15 to commemorate the birth anniversary of Birsa Munda, a prominent religious leader and tribal freedom fighter of the 19th century. Born on November 15, 1875, in the Bengal Presidency, Birsa Munda became a folk hero for the Munda people, one of India's largest scheduled tribes, as he fought against British colonial oppression and the exploitation of tribal lands. The day is marked by celebrations among the Munda community, particularly in states like Jharkhand, Odisha, Chhattisgarh, Madhya Pradesh, and Tripura. Birsa Munda's legacy includes his efforts to revive traditional tribal culture and religion, and he is remembered as a prophet who sought to reestablish the Munda Raj. His movement led to some concessions from the colonial government, including a law to protect tribal lands. The observance of Birsa Munda Jayanti reflects the ongoing significance of his contributions to tribal rights and identity.
