Explanation:

The Delhi Conspiracy case, also known as the Delhi-Lahore Conspiracy, refers to a conspiracy in 1912 to assassinate the then Viceroy of India, Lord Hardinge, on the occasion of transferring the capital of British India from Calcutta to New Delhi. Hatched by the Indian revolutionary underground in Bengal and Punjab and headed by Rash Behari Bose, the conspiracy culminated on the attempted assassination on 23 December 1912 when a homemade bomb was thrown into the Viceroys's Howdah when the ceremonial procession moved through the Chandni Chowk suburb of Delhi.
