Sejong the Great (Korean pronunciation: [sʰe(ː)dʑoŋ]; 15 May 1397 - 8 April 1450) was the fourth king of Joseon-dynasty Korea. Born with family name Yi (pronounced [i(ː)]; Hangul; Hanja), given name Do (; ), family origin Jeonju ([tɕʌndʑu]; 전주; 全州), sobriquet Wonjeong (원정; 元正). He was the third son of King Taejong and Queen consort Min. He was designated as heir-apparent, Crown Prince, after his older brother Jae was stripped of his title. He ascended to the throne in 1418. During the first four years of his reign, Taejong governed as regent, after which his father-in-law, Sim On, and his close associates were executed.

Sejong reinforced Confucian policies and executed major "legal amendments" (공법; 貢法). He also created the Korean alphabet Hangul, encouraged advancements of scientific technology, and instituted many other efforts to stabilize and improve prosperity. He dispatched military campaigns to the north and instituted the Samin Policy (사민정책; 徙民政策) to attract new settlers to the region. To the south, he subjugated Japanese raiders and captured Tsushima Island.
