Muhammad Bin Tughlaq shifted his capital from Delhi to Daulatabad. It appears that the Sultan wanted to make Deogir second capital so that he might be able to control south India better. Deogir was named Daulatabad. However, after a couple of years, Muhammad Tughlaq decided to abandon Daulatabad largely because he soon found that just as he could not control south India from Delhi, he could not control North from Daulatabad.
