Kanpur was a tinderbox in the independence and literary movements during the 1900-1950 period. The largest shopping centre is named Navin Market, after the poet Bal Krishna Sharma aka "Navin". Later poets included Gopal Das "Niraj" who also had a successful spell writing songs for "Bollywood" movies. Kanpur is also the birth place of Shyamlal Gupta `Parshad', composer of the famous ditty Vijayee Vishwa Tiranga Pyara . The propagation and popularization of Hindi also owes much to this city, with great Hindu literatteurs like Acharya Mahavir Parasad Dwivedi, Ganesh Shankar Vidyarthi, Pratap Narain Mishra and Acharya Gaya Prasad Shukla `Sanehi'. The Agricultural University is named after the revolutionary Chandrashekhar Azad and the Medical College after Ganesh Shanker Vidyarthi; both men spent much time in Kanpur. While ChandraShekhar 'Azad' was born in a village in nearby district of Unnao and shot himself when surrounded by a huge posse of British soldiers at Alfred Park, Allahabad, Ganesh Shankar Vidyarthi was killed during the Hindu-Muslim riots of 1948 at Kanpur in Phoolbagh.
