It was against the colonial bias that nationalist art emerged, and the Bengal School of Art, as nurtured by Abanindranath Tagore and E. B. Havell, was a prime example. India’s first nationalist art school, Kala Bhavana, was set up in 1919 as part of the newly established Visva-Bharati University in Shantiniketan, conceptualised by poet Rabindranath Tagore. Apart from the famous Bauhaus exhibition that travelled to Calcutta modern European art influenced Indian artists through art magazines that were in circulation. Gaganendranath and poet–painter Rabindranath, knew about the international trends of Cubism and Expressionism, which had rejected academic realism and experimented with abstraction; They thought that art need not copy the world but create its own world out of forms, lines and colour patches.
