Yi Hwa (1348–1408) or formally called Grand Prince Uian, was a warrior and scholar in the late Goryeo periods[3] who became part of the early Joseon dynasty royal family member as the fourth son of Yi Jachun,[1][3] making him half younger brother to Yi Seonggye, its founder.
He served as an assistant commander to his half older brother, Yi Seong-Gye (이성계), then after he founded the Joseon dynasty[4] in 1392, Yi Hwa was honoured as Count Uian (의안백, 義安伯)[5] and after helped his half nephew, Yi Bang-Won (이방원) in defeated in the 1st rebellion, Uian become Jeongsagongsin (정사공신).[6]
Later in 1400 during the 2nd rebellion, Yi went out again under the command from Bang-Won. Uian, along with Yi Suk-Beon (이숙번; formally called Prince Anseong, 안성군) and Yi Baek-Gang (이백강; formally called Prince Cheongpyeong, 청평군) were got the target[7] and succeeded in defeated Yi Bang-Gan (이방간; formally called Grand Prince Hoean, 회안대군) and Yi Maeng-Jong (이맹종; formally called Prince Uiryeong, 의령군), then he was promoted to Jwamyeonggongsin (좌명공신, 佐命功臣)[8] along with 47 others.[9]
From all of his successions include in defeated Jeong Mong-ju with Bang-won, Yi Hwa then became the richest nobleman in the Early Joseon period and often got promoted until passed the 4 positions in military. Although he had title, such like: "Count Uian" and "Duke Uian", but after Bang-won (a.k.a. Taejong) reorganized the royal titles system and abolished the 5 Deungjak (오등작[10]), Yi Hwa then was elevated to Grand Prince Uian (의안대군, 義安大君). According to the old tradition that an illegitimate child (especially son) couldn't had the same rank like the legitimate one, Yi Hwa became the one who was actually the illegitimate heir of Hwanjo whom his rank was elevated and same like Hwanjo's legitimate heir for seeing about his contributions in helped Seong-gye established the new dynasty.[11]
Although his descendants had time to suffered a lot from their fate to just became a farmer until King Jeongjo of Joseon and King Sunjo of Joseon's reign, their lives be more better than before. It is said that in nowadays, almost of Yi Hwa's descendants live better now and have the nice home in Seoul City, South Korea.[11]
