Liu Jun, Emperor Xiaowu of Liu Song: Emperor Shizu Xiaowu as Depicted in "Zizhi Tongjian"

Brief Introduction

Liu Jun (430–464) was the third emperor of the Liu Song dynasty during the Southern Dynasties. His temple name was Shizu, and his posthumous name was Emperor Xiaowu, hence the combined title "Emperor Shizu Xiaowu". He reigned for fourteen years (453–464), marking a critical turning point from prosperity to decline for the Liu Song regime. In his early years, Liu Jun campaigned alongside his father and possessed military talent. Initially, he ruled diligently, attempting to restore the prosperity of the "Yuanjia Era". However, in his later years, he indulged in pleasure, leading to court chaos and laying the groundwork for the fall of the Liu Song dynasty.

Core Knowledge Points

* Path to Succession: In the 30th year of Yuanjia, Crown Prince Liu Shao killed his father and usurped the throne. Liu Jun raised an army to punish him, killing his brother to ascend the throne. This is known as the "Jinghe Rebellion," which established the foundation of his rule.
* Northern Expeditions: During his reign, he launched multiple wars against Northern Wei, such as the Northern Expedition at the end of the Yuanjia era. Although some local victories were achieved, it drained national strength and failed to change the North-South confrontation pattern.
* Yongming Reforms: Initially, he rectified official administration and implemented policies under the "Yongming" era name, attempting to restore the economy, but enforcement weakened in later years.
* Later Indulgence: In his later years, he lived extravagantly, trusted sycophants, and alienated the imperial clan. This intensified internal conflicts, triggered multiple rebellions, and weakened centralization.
