Abd-er-Rahman, a brave prince of a family that had ruled Damascus, was born in troubled times in the camp before that city. Es-Deffah had seized upon the throne; the family of the Omeyyads was hurled from power. While under sentence of death for his attempt to restore the fortunes of his family, Abd-er-Rahman passed a period of wandering among Arab herdsmen. His dream was of Andalusia, where the supporters of the Omeyyads were still numerous and powerful; and by dint of energy and enthusiasm the young prince contrived to form a corps of one thousand Arabs. Abdulmalek Ibn Kattan, who had usurped rulership in Cordova, had been defeated by the adventurous Balj at the head of a troop of Syrians. The luckless Abdulmalek, after falling into the hands of Balj, was crucified in a field outside Cordova, with a hog on one side and a dog on the other. Until recovered by friends and removed for burial, the body of the conquered sultan was left upon the cross as a menace to his followers. But Balj enjoyed only a short spell of power, for at the end of eleven months he was forced to encounter the redoubtable prince of the Omeyyads, whose army of Arabs was largely augmented by fierce partisans in Spain. Marching upon Cordova, Abd-er-Rahman besieged the city. Balj was wounded, and his injuries caused his death. From this time, for about three centuries, the capital of Andalusia was held by the Omeyyad line, and during this rule the city reached the highest stage of its might and magnificence. The Arab writers state that the independent khalifate of Cordova was founded by Abd-er-Rahman I., after conquering Yusuf, who reigned in the city. Yusuf resisted the Omeyyad troops outside the walls of Cordova, and, being worsted, he retired. Abd-er-Rahman then entered the city, and appointing the command to Abu Othman, went in pursuit of the remnant of Yusuf’s army. Meanwhile Yusuf counter-marched, returned to Cordova, and assailed Abu Othman, promising him future security for himself and his relatives if he would surrender. It is said that Othman refused to accept the terms of surrender. But eventually Yusuf and Abd-er-Rahman came to an agreement, and both monarchs lived in the city (A.D. 757) in amity. The treaty was, however, afterwards broken by Yusuf, who left his palace, collected a force, and made war in Andalusia. He was frustrated by the Governor of Seville, but after the conflict Yusuf escaped to Toledo. Here he was recognised in the street, and murdered, by spies who hoped to receive reward for their fealty to Abd-er-Rahman. Yusuf’s head was sent to Cordova, and nailed to an arch of the bridge, together with the head of his son.
