the article can not be comprehensive without the summary of history in the relevant landmass prior to its formation as a modern state The title History of Pakistan implies the History of the political entity Pakistan and not necessarily the geographical landmass Any pre 1947 events relevant to the formation of the entity must be mentioned in the article for the article to be comprehensive That s the standard practice with most if not all encyclopedias although I m proposing this here not because many others do it but because it makes a lot of sense
