Kallol (Bengali: কল্লোল) refers to one of the most influential literary movements in Bengali literature, which can be placed approximately between 1923 and 1935. The name Kallol of the Kallol group derives from a magazine of the same name (which translates as 'the sound of waves' in Bengali). Kallol was the main mouthpiece for a group of young writers starting their careers around that time including Premendra Mitra, Kazi Nazrul Islam, and Buddhadeb Basu. A number of other magazines that followed Kallol can also be placed as part of the general movement. These include Uttara (1925), Pragati (1926), Kalikolom (1926), and Purbasha (1932).
