The confrontation made little progress but finally a revolt in Bukhara and Samarkand turned Ulugh Beg's attention back to those cities. It's not clear how or why the revolt of Bukhara and Samarkand took place but what is known is that Abdal-Aziz Mirza was a bad administrator and had irritated the military establishment some how. The Arghuns were the chief men of this group in Samarkand and the Bukhara clergy (Naqshbandi Sufis) are known to be promoters of the revolt as well.
