Kalinjar town, then the capital, was unsuccessfully besieged by Mahmud of Ghazni in A.D.
Sher Shah was killed at the storming of Kalinjar (1545), and Humayun, returning to India with Akbar, then only thirteen years of age, defeated the Indo-Afghan army and reoccupied Delhi (1555).
The mines of Maharajpur, Rajpur, Kimera and Gadasia have been famous for magnificent diamonds; and a very large one dug from the last was kept in the fort of Kalinjar among the treasures of Raja Himmat Bahadur.
In 1809 Ajaigarh was besieged by a British force, and again three years later Kalinjar was besieged and taken after a heavy loss.
But Sher Shah was killed at the storming of the rock-fortress of Kalinjar, and Humayun, after many vicissitudes, succeeded in re-establishing his authority at Lahore and Delhi.
