When British archaeologist Sir Mortimer Wheeler was commissioned in 1947 by the government of Pakistan to give a historical account of the then new nation, he entitled his work Five Thousand Years of Pakistan. Indeed, Pakistan has a history that can be dated back to the Indus Valley civilization,the principal sites of which lay in present-day Sindh and Punjab provinces. Pakistan was later the entryway for the migrating pastoral tribes known as Indo-Aryans, or simply Aryans, who brought with them and developed the rudiments of the religio-philosophical system of what later evolved into Hinduism. They also brought an early version of Sanskrit, the base of Urdu, Punjabi, and Sindhi languages that are spoken in much of Pakistan today.
The pride that Pakistan displayed after freedom in its long and multicultural history has disappeared in many of its officially sponsored textbooks and other material used for teaching history .As famous anthropologist Akbar S. Ahmed has written in History Today, "In Pakistan the Hindu past simply does not exist. History only begins in the seventh century after the advent of Islam and the Muslim invasion of Sindh."
