The kingdom of caubul,in two volumes,(vol.1 422 pages and vol.11 465 pages )is a truely landmark book on the subject of afghanistan and Afghans.Its a master piece and can be called as an authority on the subject.It is an encyclopaedic writing which covers almost everything relating to afghans,viz,geography,history,culture,beliefs,ethnicity,trade and commerce,rivers,mountains,cities and towns,climate,law ,military,Afghan"s neighbours etc.Though written in 1808 by the celebrated
Mounstuart Elphinistone, it is still very much valid,its indeed a treasure of information.The style of the book is also very attractive.It appears that the book was primarily written with the idea of occupying that country which actually happened subsequently in the shape of 1st and 2nd Anglo- Afghan wars,entailing catastrophe for afghan and english people.While dealing with history,the sources have not been mentioned which may be because of abscence of written material in afghani language at that period of time.The book can really be called the single most important authortative account of Afghan-Pukhtun nation even this day.
