On what legal grounds does India claim the region of Kashmir ?
Akhand Bharat , literally Undivided India , is an irredentist call to reunite Pakistan and Bangladesh with India to form an " Undivided India " as it existed before partition in 1947 ( and before that , during other periods of political unity in South Asia , such as during the Mauryan Empire , the Gupta Empire or the Mughal Empire ) .
