In the beginning of the 19th century there was a new awakening in Bengal. This was the result of the impact of foreign thought, philosophy and educational system. The impact was confined to the English educated youth of Bengal. This group called itself `Young Bengal`. Henry Vivian Derozio was the leader of the Young Bengal Movement. He was a teacher at Hindu College Calcutta. He inspired his students and taught some thoughts such as to think rationally, to question all authority, to love liberty, equality and freedom and to worship truth. The chief characteristic of the group was to criticize all traditions and customs. This group did not have any permanent impact on the residents of Bengal because it lacked organizational framework and did not have any constructive programme of reform. But Rama Mohan Roy was the best representative of the rational thought which was a direct result of the Young Bengal Movement. He wanted to reform Hinduism in such a way that it might have a rational basis for all its principles and practices. He, therefore, laid emphasis on the essential unity of the three main religions. And these are Hinduism, Islam and Christianity.
