Explanation:

Kartar Singh Sarabha (24 May 1896 – 16 November 1915) was a Sikh revolutionary who was among the most famous and reputed martyrs of Punjab. When he turned 16, his grandfather sent him to the University of California at Berkeley to study Chemistry.He was 17 years old when he became a member of Ghadar Party, then came up as a leading luminary member and started fight for an independent India. He was one of the most active members of the movement. Singh was executed at Lahore in November 1915 for his role in the movement in February 1915 when he was merely 19 years old.
He was sent to trial with the other Gadarites at Lahore in what came to be called the First Lahore Conspiracy case. The judgment was pronounced in September 1915. Due to large public outcry, of the 27, the sentence of 17 of the Gadarites was changed from death to imprisonment and deportation for life in the Andaman Cellular jail, at the last minute following the intervention of Lord Hardinge, the Governor General of India.He soon became the symbol of martyrdom and many were influenced from his bravery and sacrifice. A Punjabi novelist Nanak Singh wrote a novel titled “Ikk Miyan Do Talwaran” based on his life. A page of the first Lahore Conspiracy Case's judgement in which Kartar Singh Sarabha was sentenced to death and on which Singh put some notes is also displayed in Shaheed-e-Azam Sardar Bhagat Singh Museum.
