Sultan Muhammad-bin Tughluq has been described by some as a
‘mad king’. For, all his projects like the transfer of capital from Delhi
to Daulatabad, introduction of token currency, experiment in Doab
and expedition to Kangra were all unsuccessful.
Not only that, his experiments set those forces into play which
eventually led to the disruption of the Delhi Sultanate. Also the Delhi
Sultanate was financially ruined. Despite all this modern historians
point out the intrinsic merits of some of his projects. It has been
pointed out by Satish Chandra that Muhammad-bin Tughluq
actually wanted to establish a second capital, not transfer of capital
from Delhi to Daulatabad.
Again, the introduction of the token currency was a modern
concept. Where he failed was not being able to take proper
measure to prevent imitation of the currency.....................go through the book and find his doings.
