A brief interregnum ensued, during which the all-powerful Saiyids sought to administer the powers of sovereignty behind the screen of any royal scion they could find of the requisite nonentity. But there was a Nothing still more absolute than any they could find; and after two of these shadow-kings had passed in about seven months, one after the other, into the grave, the usurpers were at length constrained to make a choice of a more efficient puppet. This was the son of Bahadur Shah's youngest son, who had perished in the wars which followed that emperor's demise. His private name was Sultan Roshan Akhtar ("Prince Fair Star"), but he assumed with the Imperial dignity the title of MOHAMMAD SHAH, and is memorable as the last Indian emperor that ever sat upon the peacock throne of Shah Jahan. The events mentioned in the preceding brief summary, though they do not comprehend the whole disintegration of the Empire, are plainly indicative of what is to follow. In the final chapters of the First Part we shall behold somewhat more in detail the rapidly accelerating event. During the long reign of Mohammad foreign violence will be seen accomplishing what native vice and native weakness have commenced; and the successors to his dismantled throne will be seen passing like other decorations in a passive manner from one mayor of the palace to another, or making fitful efforts to be free, which only rivet their chains and hasten their destruction. One by one the provinces fall away from this distempered centre. At length we shall find the throne literally without an occupant, and the curtain will seem to descend while preparations are being made for the last act of this Imperial tragedy. CHAPTER III. A.D. 1719-48 Muhammad Shah — Chin Kulich Khan, his retirement from Dehli — Movements of the Mahrattas — Invasion of Nadir Shah — Ahmad Khan repulsed by the Moghuls.
