I've made an edit that includes the rest of what was said in that entry about the Ghurids in the reference section and I’ve made the edit to the main article to reflect the uncertainty of the reference.  

 I'll continue to do research as I have strong doubts about the Ghurids being composed primarily of "Tajiks", currently numbering approx 20 million, compared to the current 40 million Pashtuns whose culture was much more militaristically oriented and who had occupied much of the area that the Ghurid Empire encompassed. . 

 I have less of a doubt that the founder of the Ghurids was of Tajik origin, although born and raised in the borders of modern day Afghanistan. The meaning of “Tajik” has been given a fairly liberal definition but a distinction should be realized for Pashtuns due to distinct genetics, culture and society. Short of this would be a disservice to the readers.  

 I stand open to correction. Thanks.
