Having rebuilt the mausoleum of the Imaum Hanbal, which had been ruined by the inundations of the Tigris, Timur marched into Georgia, in 1394, and drove all who opposed him into the fastnesses of the mountains. He sent the different corps of his army in various directions, to reduce the people to submission, while he relaxed the toils of conquest, by hunting and festivity. At this time the births of his two grandsons, Ulugh Beg and Ibrahim Sultan, were celebrated, with great splendour, on the plains of Kars. The throne of Timur was raised in the midst of magnificent tents, with lovely damsels ranged around it. Musicians and singers were grouped behind, and the Meerzas, Amirs, Nevians, and foreign lords from Iran and Touran, joined their voices in prayers for the prosperity of the mighty sovereign. The festivities lasted for eight days. This short relaxation was interrupted by an irruption of the army of Toktamish through the gates of Derbent, in the Caucasus. The Khan of Kapchak had recovered from the chastisement inflicted on him, during Timur's memorable campaign, and had once more renewed hostilities. The conqueror, therefore, again prepared for war, and reviewed his vast army, on a plain about twentyseven miles south of Derbent, in a line extending from the Caucasus to the shores of the Caspian. He then led his forces over the pass near Mount Elbourz, and again encountered the army of Toktamish. The cavalry, on both sides, fought fiercely, and charged each other with desperate speed; but victory again declared on the side of her favourite, Toktamish fled into the wilds of Siberia, and Timur, halting on the plains of Astrakhan, installed a son of Urus Khan, as the new Khan of Kapchak.
