Why might location have played a role in the split between Pakistan and Bangladesh?

Answer 1

Pakistan got Bangladesh because they both were Muslim's land. But Bangladesh is similar to India. There were 35% people Hindu in Bangladesh. Pakistan forced Bangladesh to speak Urdu which one is official language of Pakistan. But Bengali is more traditional and older than Urdu. After Tamil is Bengali in older language of South Asia. Bengali is 6th largest worldwide language. Pakistani culture is differ than Bangladesh. West Bengal, Tripura, Assam & some other states speak Bengali and they were separated from Bangladesh because they didn't like Pakistan. That's why Bangladesh got help from India.

Answer 2

There are main two reasons which I believe are responsible for the separation of east and west Pakistan:

1) Geographical area between East and west Pakistan

2) Sheikh Mujib's 6 point formula (which is totally against Pakistan) like shift capital from Islamabad to Dhaka (somehow agreeable), his own force, his own tax system, own currency ( that time your part of Pakistan) etc., and above all the role of Hindu teachers (90% of teachers in east Pakistan are Hindu, the role of Mukhti bhani (the so called freedom fighters) and the role of India also.

This terrorist wing is responsible of killing of Shieikh Mujib also.

North Pakistani forces had lost contact with west Pakistan due to that they get a chance to hold Pakistan army.
