郭子仪
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.
