Then, the term was used by Bengali patriotic songs like Namo Namo Namo Bangladesh Momo, by Kazi Nazrul Islam, and Aaji Bangladesher Hridoy, by Rabindranath Tagore.[34][35] Bangalees, an exonym for Bengalis, was used between 1972 and 1978 by the Constitution of Bangladesh for all citizens of Bangladesh, despite 2% of the population being indigenous and immigrant non-Bengalis. Under President Ziaur Rahman, the constitutional term was changed to Bangladeshi, as part of efforts to promote Bangladeshi nationalism.[36] The term "Bangalee" is still used to denote people of Bangladesh as a nation.[37]
