These usurpers were completely extirpated by the house of Merini, which family in its turn was overcome by _Muley Mahomet_, a Xeriffe of the same tribe, who seized the reins of government. His successors did not long enjoy the fruit of their usurpation, but were most dreadfully disturbed by a series of revolutions and murders, fomented and perpetrated by the mountaineers, a resolute, ferocious, and restless people, who, after raising the various parts of the country in arms one against the other, and subjecting them to all the calamities of civil war, cruelly butchered _Muley Achmet_, the last of the sons of _Muley Sidan_ and proclaimed their chief, _Crom-el-Hadgy_, a bloodthirsty ruffian, of low birth, and eminent in cruelties, in his stead. This tyrant, to secure his new acquisition, inhumanly massacred all the male descendants of the Xeriffes. He soon became the object of universal detestation, and was poignarded by his Sultana on the day of marriage. She was of the family of the Xeriffes, and consented to marry him, only that she might have a better opportunity of sacrificing him to her revenge, for the murder of her family. After the tragical end of the descendants of the Xeriffes, these countries, but more especially the province of Tafilet, experienced all the horrors of famine and pestilence, for several years. The people of Tafilet considered it as a judgment from their Prophet for their injustice; and, to appease him, they made a pilgrimage to Mecca, and easily prevailed on a Xeriffe, a descendant of Mahomet, named _Muley Aly_, who resided in a town near Medina, to accompany them back to this country. In the mean time, the seasons having become more genial, the harvests were so abundant, that this credulous and superstitious people attributed the change entirely to the arrival of the pious Xeriffe. He was unanimously proclaimed King of Tafilet, by the name of _Muley Xeriffe_; and as such acknowledged by the other provinces, with the exception of Morocco and its environs, which were then in the possession of _Crom-el-Hadgy_, who having ended his career in the manner described, was soon followed by his son; and the ancient families who had ruled the empire being completely extinct, the new King of Tafilet, from his birth, religion, and the public election, was confirmed the legitimate Sovereign of the whole county.
