His early reign, the Kaiyuan era (713–741), is remembered as the high point of the Tang. In later years he left the government to his ministers and doted on
杨贵妃. When
安禄山 rebelled in 755 he fled toward Sichuan; at
马嵬坡 his troops forced him to have her killed, and he soon gave up the throne to his son.
白居易's 《
长恨歌》 tells the story.
