Genghis Khan left his empire with such a firm foundation that it continued growing for another 150 years. Then, in the centuries that followed its collapse, his descendants continued to rule a variety of smaller empires and large countries, from Russia, Turkey, and India to China and Persia. They held an eclectic assortment of titles, including khan, emperor, sultan, king, shah, emir, and the Dalai Lama. Vestiges of his empire remained under the rule of his descendants for seven centuries.
