March 23 is marked as Shaheed Diwas or Martyrs’ Day to remember the day when three brave freedom fighters were hanged by the British.
On March 23, 1931, Bhagat Singh along with his associates Sukhdev Thapar and Shivaram Rajguru were hanged to death for the assassination of 21-year-old British police officer John Saunders.
The day they were executed is celebrated as Martyrs' Day throughout the country.
Bhagat Singh was a socialist revolutionary and freedom fighter who was executed at the age of 23 for his dramatic violence against the British rule.
They mistook Saunders for Superintendent James Scott, who was responsible for leading a lathi charge against Lala Lajpat Rai, who along with his followers was protesting against the Simon Commission.
Lala Rajpat Rai succumbed to his injuries a few days later.
Bhagat Singh, Sukhdev and Rajguru were hanged to death 11 hours before the scheduled time for the Saunder's murder case.
