Sun Hao, born in the year two hundred forty-three, was the fourth and final emperor of the Eastern Wu state during China's tumultuous Three Kingdoms period. Originally named Sun Pengzu and later known by the courtesy name Yuanzong, he was the son of Sun He, who had once been the heir apparent to the founding emperor, Sun Quan.
Ascending to the throne in September of two hundred sixty-four following the death of his uncle, Sun Xiu (Emperor Jing), Sun Hao was initially seen as a preferable choice by the populace, who yearned for a more mature leader in the wake of the fall of Wu's ally, Shu Han. However, his reign quickly became marked by cruelty, extravagance, and a profound inability to manage domestic affairs.
As a result of his misrule, the Eastern Wu state faced dire consequences, ultimately leading to its conquest by the Jin dynasty in the year two hundred eighty, which signaled the end of the Three Kingdoms era. Sun Hao's legacy is further complicated by the titles he held, including Marquis of Wucheng before his ascension, and later, the titles of Marquis Guiming, Later Lord of Wu, and Last Emperor of Wu, which historians have used to refer to him.
