Many debates and discussions failed to establish unanimous acceptance of any theory. The split of Islamic pakistan proved one thing beyond any doubt that religion alone cannot unite nations/different territories. Language, culture, local scenerio, geographical conditions etc have their impact. East Bengal and West Pakistan were alienated in early 50's when the west wanted the east to give up their rich language, Bengali/ the Bengali-literature, their folk music, dance etc; and accept Urdu. People of west were stronger built, fair-complexioned, taller and they looked down on the eastern people. Finally, in spite of getting majority in their Parliamentary election the eastern leaders were refused to form the government by the western leader and the army that was dominated by the west, the final nail was driven in to split the Two Parts.
