Xiao Zhaoye (蕭昭業; 473–494), often known by his posthumously demoted title of Prince of Yulin (鬱林王), courtesy name Yuanshang (元尚), nickname Fashen (法身), was an emperor of the Chinese dynasty Southern Qi. He is known as the Prince of Yulin because that was the title he was posthumously demoted to after his granduncle Xiao Luan assassinated him in 494. During his brief reign, he was known as overly devoting his time on games and pleasure, unaware that the ambitious Xiao Luan had targeted him for removal, and after his death, Xiao Luan briefly made his brother Xiao Zhaowen emperor, but then seized the throne himself.
Xiao Zhaoye was born in 473, when his great-grandfather Xiao Daocheng was a Liu Song general. Initially, after Xiao Daocheng seized the throne in 479, ending Liu Song and establishing Southern Qi (as its Emperor Gao), Xiao Zhaoye's father Xiao Zhangmao, as the oldest son of the crown prince Xiao Ze, was created the Prince of Nan Commandery. Xiao Zhaoye's mother Wang Baoming, Xiao Zhangmao's wife, was created the Princess of Nan Commandery. Xiao Zhaoye himself was not given any titles at the moment. He was the only son of Xiao Zhangmao born of Princess Wang, as she was not much favored by her husband.
In 482, after Emperor Gao died, Xiao Ze succeeded him as Emperor Wu. Xiao Zhangmao was created the Crown Prince, and Xiao Zhaoye, as Xiao Zhangmao's oldest son, was given his father's old title of Prince of Nan Commandery. In 484, at age 11, he married He Jingying as his princess.
On the surface, when Xiao Zhaoye was the Prince of Nan Commandery, he was thought to be studious, careful, filially pious, elegant in his behavior, and dexterious. Therefore, his grandfather Emperor Wu favored him greatly. However, when not in the presence of his grandfather or father, Xiao Zhaoye was instead frivolous and spending time with people who were bad influences. During this time, he lived with his uncle Xiao Ziliang (蕭子良) the Prince of Jingling in Xifu (西府), an important suburb of the capital Jiankang. As Xiao Zhangmao often limited his activities and budget, Xiao Zhaoye often borrowed money from rich households, who would not dare to refuse. He also duplicated a set of keys for the fortress gates so that he could spend night time in games at various military camps. Exasperated, his teachers Shi Renzu (史仁祖) and Hu Tianyi (胡天翼), believing that they and their households would be in trouble regardless of whether they informed this to Emperor Wu or Crown Prince Zhangmao or not, both committed suicide. Xiao Ziliang's wife Princess Yuan raised him with love, but Xiao Zhaoye, as he grew, became suspicious that his uncle was interested in taking the throne himself.
