조선 태조
General Yi Seong-gye (posthumously known as Taejo of Joseon) established the "Kingdom of Great Joseon" in 1392–1393, and he founded the Yi dynasty which would retain power on the Korean peninsula for five hundred years. An early achievement of the new monarch was improved relations with China; and indeed, Joseon had its origin in General Yi's refusal to attack China in response to raids from Chinese bandits. The Joseon foreign policy would evolve from pre-existing foundations. For example, Goryeo envoy Jeong Mongju travelled to Japan in 1377; and the consequences of his efforts were only seen later.
