Punjab Kesari (aka Shere Punjab) Lala Lajpat Rai; 30 October 1928, at Lahore

Simon Go Back Against the Simon Commission: The Indian Statutory Commission was a group of seven British Members of Parliament that had been dispatched to India in 1927 to study constitutional reform in that colony. It was commonly referred to as the Simon Commission after its chairman, Sir John Simon. Ironically, one of its members was Clement Attlee', who subsequently became the British Prime Minister who would oversee the granting of independence to India and Pakistan in 1947.

It might be noted that during the protest of Simon Commission, the leader of Punjab Lala Lajpat Rai was killed by the police, which in turn lead to violent Indian protests including bombing of the assembly and revenge murder of a British Police Officer.
Following Indians struggles for independence, the British government constituted a council of seven British Parlimentarians headed by Sir John Simon to reform the governing of India. The team
arrived in India in 1927, but was met with severe protests as it didn't include any Indian representative.

"Simon Go Back!" was the war cry of the masses, as the commission showed no intention of accepting the Indians' demand for Swaraj.
