was peace and happiness. As a reward, the Jade Emperor had Guo guided to heaven and bestowed the Celestial post of "God of Prosperity and Happiness" to him. Legacy Guo Ziyi has been credited by many historians with putting down the An Lushan Rebellion, characterizing him as the man who single-handedly saved the Tang dynasty. His impact on East Asia was also dramatic in that he renewed Tang relations with many of its Uyghur allies, who later supported the dynasty in campaigns against the Tibetan Empire. After his various victories over the Tibetans they were never able to restore their military might and lost much of their political strength in Asia. In 757, or thereabouts, Guo Ziyi saved the renowned poet Li Bai from a death sentence for treason by offering Emperor Suzong of Tang his own official rank in exchange for Li Bai's life. In the event, Suzong commuted Li Bai's sentence to exile, and later pardoned him, and Guo Ziyi was allowed to retain his rank. Future members of his family would also go to become famous generals, among them Guo Puyo, a general greatly used by Genghis Khan, and Guo Kan, one of the best generals of the Mongol Empire, who was instrumental in the Mongol Siege of Baghdad (1258) and the destruction of the Abbasid caliphate which saw the execution of the last Abbasid caliph and the slaughter of 800,000-2,000,000 Arab Muslim civilians in Baghdad, with only the Nestorian Assyrian Christians being spared.
