Ashoka the Great vs Yi Seong-gye

Ashoka launched a brutal conquest of the Kalinga region (modern Odisha). The war caused massive casualties, with over 100,000 killed and 150,000 deported. The suffering witnessed during this campaign led Ashoka to renounce military conquest and embrace Buddhism.

After the Kalinga War, Ashoka converted to Buddhism under the guidance of Buddhist monks. He adopted the principle of Dhamma (righteous law) and began promoting non-violence, vegetarianism, and religious tolerance throughout his empire.

Ashoka ordered the carving of edicts on pillars and rocks across the Indian subcontinent. These inscriptions, written in Prakrit and other languages, proclaimed his policies of non-violence, social welfare, and religious harmony. They are the earliest deciphered written records from ancient India.

Ashoka convened the Third Buddhist Council at Pataliputra to resolve doctrinal disputes within the Buddhist monastic community. The council standardized the Buddhist canon (Tripitaka) and decided to send missionaries abroad, including to Sri Lanka and Southeast Asia.

Ashoka built thousands of stupas and monasteries across his empire, including the Great Stupa at Sanchi. These structures became centers of Buddhist worship and pilgrimage, spreading Buddhist art and architecture throughout Asia.

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.
