Yi Hoe-yeong
Sold his family estate with his five brothers and founded the Gyeonghaksa and Sinheung school in western Jiandao
Known as Udang, he was the fourth son of Yi Yu-seung, Minister of Personnel, in a distinguished Seoul family descended from Yi Hang-bok. Holding that status should not divide people, he is said to have freed the family's slaves. In 1907 he founded the Sinminhoe with Ahn Chang-ho, Yang Gi-tak and others, and worked behind the scenes with Yi Sang-seol on the mission to The Hague.
After the annexation he and his five brothers, including Yi Seok-yeong and Yi Si-yeong, sold their vast estates and moved with dozens of family members to Samwonbo in western Jiandao. In 1911 he founded the Gyeonghaksa with Yi Sang-ryong and others and opened the Sinheung School (later the Sinheung Military Academy) to train independence fighters. In 1918 he planned to bring the former emperor Gojong into exile in Beijing as a rallying point, but Gojong's sudden death ended the plan.
He later embraced anarchism, founding the League of Korean Anarchists in China in 1924 and supporting militant actions in Beijing and Shanghai. With the brothers' fortune spent, his family often went hungry. In 1932, on his way to set up a base in Manchuria, he was arrested at Dalian and died under torture in Lüshun Prison on 17 November, aged sixty-five. He was posthumously awarded the Independence Medal in 1962.
