The Sultanate of Delhi, 711–1526 A.D. c19.s6.4

c19.s6.4

Seeing that huge Mongol armies had twice reached Delhi without any hindrance or opposition on the way, Ala-ud-din took effective measures to protect the frontier so as to prevent a future raid on his capital. He repaired the old forts in the Panjab, Multan and Sindh, and built new ones. All these were garrisoned with powerful troops. Besides, he posted an additional army charged with the duty of guarding the frontier. He appointed a special governor of the frontier region who became known as the Warden of the Marches.
