why did mohd bin tughlaq change his capital from delhi to daultabad ?why did he shift it back?

Mohammad bin Tughlaq shifted his capital from Delhi to Daulatabad in order to control the Deccan region more effectively and establish a capital that was geographically closer to the centre of his kingdom. He shifted it back to Delhi as the northern regions of the country started to go out of his control and the people disliked the forced migration from Delhi to Daulatabad.
