Qin Shi Huang vs Yi Seong-gye

Qin Shi Huang commissioned a vast mausoleum complex near Xi'an, guarded by thousands of life-sized terracotta soldiers, horses, and chariots. The project employed hundreds of thousands of workers and reflected his obsession with immortality and imperial power.

From 230 to 221 BCE, Ying Zheng led the Qin state in a series of campaigns that conquered the Han, Zhao, Wei, Chu, Yan, and Qi states. This unified China under a single ruler for the first time, ending the Warring States period.

Qin Shi Huang ordered the standardization of Chinese script, currency, and weights and measures across the unified empire. This facilitated administration, trade, and cultural integration, laying a foundation for future dynasties.

After conquering the last independent state, Ying Zheng declared himself Shi Huangdi (First Emperor), founding the Qin Dynasty. He adopted a new title to signify his supreme authority and initiated centralized imperial rule.

Qin Shi Huang ordered the connection and extension of existing northern fortifications to create a unified defensive wall against nomadic Xiongnu raids. This project involved massive conscripted labor and became the precursor to the later Great Wall.

On the advice of Li Si, Qin Shi Huang ordered the burning of historical records and philosophical texts not aligned with Legalist doctrine. He also had 460 Confucian scholars buried alive to suppress dissent and consolidate ideological control.

Yi Seong-gye led Goryeo forces against Japanese pirates (wokou) at the Battle of Hwangsan. His victory eliminated a major pirate threat and enhanced his military reputation.

Yi Seong-gye turned his army back at Wihwado Island rather than invade Ming China as ordered by the Goryeo court. This act of defiance led to a coup that eventually brought him to power.

Yi Seong-gye overthrew the Goryeo dynasty and founded the Joseon dynasty, becoming King Taejo. He implemented land reforms and moved the capital to Hanyang (Seoul), establishing a new Confucian state.
