Badal Gupta (1912 – December 8, 1930) was a Bengali revolutionary nationalist born in Purba village in Bikrampur region of Dhaka. Sudhir Gupta, was his original name. He fought against the British rule in the process to free India. A school teacher, named Nikunja Sen in Banaripara school of Bikrampur inspired Badal to join the Bengal Volunteers. Badal’s two paternal uncles late Nagendra Nath Gupta and Dharani Nath Gupta influenced him in revolutionary activities and created in him a strong feeling of patriotism. Both the uncles were involved in the Alipore Bomb case and put into prison along with Rishi Aurobindo Ghosh.
