Under the planned propaganda the British were trying to prove that India has no national identity of its own. Bang- Bhang movement brought the new awareness in Indian mind. Aim of the Bengal school was to regenerate the patriotism, to rediscover India’s past and to recollect Indian values in the field of arts by boycotting foreign trends and means. It was national emotion that made Bengal school nationalistic.
Dr. Anand Coomar Swami, the most noted writer of Indian art, a pioneer historian and scholar published a book ‘Art and Swadeshi’ in 1910 which was regarded as the manifesto of art of India. This book gave a plea to return to those Indian sources and ideas which were being demolished by British political fervor. He also recommended the commitment of the Bengal school and efforts of artists for giving a tremendous moral boosting to the Indian freedom movement.
Genius and creative Abanindra Nath did so and put Indian soul before the world. paintings and articles of Devi Prasad Roy Chowdhury printed in journal such as ‘Pravasi , ‘Bharatvarsha’ and shanibarer chitthi ‘ did the same job during freedom movement. In this series, Nandlal Bose copied the paintings of Ajanta and painted his famous line drawing ‘Dandi March of mahatma Gandhi’. he also painted about 60 paintings on handmade paper for Haripura congress on the request of Mahatma Gandhi. These paintings were feast of Indian arts and beautification. These paintings were also notable for their economy of means , boldness , vigour and decorative qualities. Through these paintings, Nandlal Bose combined art with nationalism and became the interpreter of Indian color and its souls. Abanindranath painted Mother India. Gaganendranath painted a caricature on the massacre of Jalianwalan Bagh which brought hatred among Indians against naked cruelty of British. the personal style developed by noted artists namely Abanindranath Tagore ,Nandlal Bose ,k. venkatapa, Gaganendranath Thakur, Shailendra Nath dey , Asit Kumar Halder and Devi Prasad Roy Chowdhury etc. saved us from the slavery of expressions and ideas which finally put the foundation of modern trends in the field of art .
