Greater Bangladesh (Bengali: বৃহত্তর বাংলাদেশ, romanized: Brihôttôr Bangladesh; among other names, see below) is a theory that the People's Republic of Bangladesh has aspirations of territorial expansion, to include the Indian states of West Bengal, Tripura and Assam's Barak valley, Hojai and Undivided Goalpara as part of its own territory. Some proponents also claim that Sheikh Hasina, Prime minister of Bangladesh and Mamata Banerjee, Chief minister of West Bengal, are involved in trying to create Greater Bangladesh.
