Emperor Xuanzong of Tang
Tang emperor whose reign saw golden age then sharp decline.
Li Longji, known as Emperor Xuanzong of Tang, was born in 685 in Luoyang, the eastern capital. He was the third son of Emperor Ruizong and his concubine Consort Dou. Described as handsome with a "majestic and beautiful" appearance, he was also musically gifted. His reign, from 712 to 756, lasted 44 years—the longest of any Tang emperor. He came to power through two palace coups, taking over an empire still in its golden age. Initially, he relied on capable chancellors such as Yao Chong, Song Jing, and Zhang Yue, who had served before his rule. However, his later trust in chancellors Li Linfu and Yang Guozhong, along with the general An Lushan, led to political errors that caused the empire to turn sharply toward decline and near collapse. The Tang golden age ended with the An Lushan rebellion.

Lore & Background
Li Longji was the third son of Emperor Ruizong, and his mother was Consort Dou. He was said to be handsome, with an appearance that was 'majestic and beautiful', and was talented in music. Li Longji's father Emperor Ruizong then retook the throne. Li Longji was made crown prince after his older brother Li Chengqi declined consideration, stating that in times of danger, achievement should be considered first. Li Longji became active and powerful in politics, while Princess Taiping also held great influence.
Reader's Guide
He initially benefited from capable chancellors like Yao Chong, Song Jing, and Zhang Yue, who were already serving before his ascension. However, his later over-trusting of chancellors Li Linfu, Yang Guozhong, and general An Lushan led to the An Lushan rebellion, which ended Tang's golden age and brought the empire to near collapse. His seizure of the throne through two palace coups—first against Empress Wei and later consolidating power under his father—demonstrates the turbulent politics of the era. His legacy is thus a turning point: from a golden age to sharp decline, marking a critical transition in Tang history.
