It has been 94 years since Bhagat Singh and his comrades Sukhdev and Rajguru were executed in Lahore jail a day ahead of the scheduled hour of execution. Since then, he is remembered by the Urdu epithet Shaheed-e-Azam (greatest martyr, or martyr of martyrs). Inquilab Zindabad (long live revolution), the slogan, again in Urdu, immortalised by Bhagat Singh, is daily invoked across India as the most popular chant of collective resolve for change and justice.
