The partition of Pakistan

When present day Pakistan was formed in 1947 it was known as west Pakistan. Two thousand kilometres east is present day Bangladesh, formerly east Pakistan (formerly east Bengal). For 23 years, two states constituted Pakistan, but appear to have little in common, besides religion reportedly.
The partition of India and Pakistan was masterminded by the British. It is called the 3 June plan.
Colonial rule in India may have begun with control of the affluent region of Bengal. Wealthy landowners were relocated, leaving their property behind. According to British sources, properties were leased to poor Muslims who were unable to pay.
During British rule, millions of people were displaced and there were many uprisings leading to millions of deaths.
