This paper endeavours to explore and evaluate the identical topics Nirad C Chaudhuri deals with in his Bangla and English writings. As a versatile writer, Chaudhuri brought about multifarious issues in his Bangla and English writings. Of his writings in these two languages, some are similar and some are dissimilar in topics. Why he made this difference while writing is a logical question to answer. Certainly, he did not write for the same audience. He wrote in Bangla for the Bangla-speaking people and in English for the English-speaking people. He wanted to share his ideas with these two communities and to remind them of their lost glories. His major identical topics are nationalism, Rabindranath, imperialism, Indo-British relations, Hindu-Muslim relations, marriage, love, sex and conjugal life, life and culture in Bengal, India and England, biographies of famous personalities etc. He thought that these topics were of common interest to both streams of readers and they will suit their mental faculties in order to awaken them from their slumber.
