What is "kallol"

Kallol 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).
