Laoshang Chanyu vs Tuoba Tao

Laoshang Chanyu succeeded his father Modu Chanyu as ruler of the Xiongnu Empire in 174 BC. He inherited a powerful confederation that dominated the steppe and maintained the tribute system with Han China established by his father.

Laoshang Chanyu launched a major campaign against the Yuezhi, a powerful nomadic group in the west. He defeated them decisively, forcing the Yuezhi to migrate westward into Central Asia, which reshaped the balance of power on the steppe.

Laoshang Chanyu renewed the Heqin treaty with the Han Dynasty, securing continued tribute payments and marriage alliances. This maintained peace between the Xiongnu and Han, allowing Laoshang to focus on expanding Xiongnu influence in other directions.

Laoshang Chanyu extended Xiongnu control over the Tarim Basin city-states, securing tribute and controlling the Silk Road trade routes. This expansion increased Xiongnu wealth and influence, making them the dominant power in Central Asia.

Emperor Taiwu of Northern Wei (Tuoba Tao) conquered the last rival state, Northern Liang, unifying all of northern China under the Northern Wei dynasty. This ended the Sixteen Kingdoms period and established Northern Wei as the dominant power in the north.

Emperor Taiwu issued an edict suppressing Buddhism, ordering the destruction of monasteries, scriptures, and images. He favored Daoism and sought to reduce Buddhist influence on state affairs. This was the first major persecution of Buddhism in Chinese history.

Emperor Taiwu was assassinated by his eunuch Zong Ai, who feared punishment for his misdeeds. The assassination plunged Northern Wei into a succession crisis, but Zong Ai was soon killed by other officials, and a new emperor was installed.
