23 March: Shaheed Diwas or Martyrs' Day

Martyrs' Day is observed on many days in India, especially on January 30 and March 23, to pay homage to the freedom fighters of our country.
While January 30 is observed as the Martyrs' Day to mark the death anniversary of Mohandas Karamchand Gandhi, the anniversary of the deaths of Bhagat Singh, Sukhdev Thapar, and Shivaram Rajguru on 23 March 1931, in Lahore, is also observed as Martyr's Day.
On the occasion of Shaheed Diwas, Prime Minister Shri Narendra Modi will inaugurate Biplobi Bharat Gallery at Victoria Memorial Hall, Kolkata.
The Gallery displays the contribution of the Revolutionaries in the freedom struggle and their armed resistance to British colonial rule.
Biplobi Bharat Gallery depicts the political and intellectual backdrop that triggered the Revolutionary movement. It showcases the birth of the revolutionary movement, formation of significant associations by revolutionary leaders, spread of the movement, formation of Indian National Army, contribution of Naval Mutiny, among others.
