Why did Muhammad bin Tughlaq transfer his capital from Delhi to Devagiri? Did he shift the entire population? Why?

Muhammad bin Tughlaq transferred his capital from Delhi to Devagiri (Deogir), which he renamed Daulatabad. This he did for two reasons. First, Daulatabad was centrally located from where he could have control over the Deccan territories. Second, he wanted to protect his capital from the continuous raids of the Mongols. Daulatabad was situated 1500 km away and was at a safe distance from the invaders. He did not shift the entire population but ordered his officers and leading men to shift to Daulatabad .
