ソンツェン・ガンポ
The Tang Empire competed with the Tibetan Empire for control of areas in Inner and Central Asia, which was at times settled with marriage alliances such as the marrying of Princess Wencheng (d. 680) to Songtsän Gampo (d. 649). A Tibetan tradition mentions that Chinese troops captured Lhasa after Songtsän Gampo's death, but no such invasion is mentioned in either Chinese annals or the Tibetan manuscripts of Dunhuang.
