The Japanese Invasion of Korea in 1592, from May 23, 1592 to December 16, 1598, was a war between Joseon and Ming China versus Japan.
It was an international war that shook the history of East Asia in the 16th and 17th centuries, with tremendous influence not only on Joseon but also Ming and Japan, which were the main stages of the war.
From the Japanese perspective, although the original purpose of 'conquering Joseon and entering the continent' was not achieved, it also gained cultural benefits such as pottery manufacturing techniques, looting metal types, and inflow of Neo-Confucianism by looting various human and material resources from Joseon.
It also re-emerged as a major player in the international situation in East Asia a thousand years after the Battle of the Baekgang River in the 7th century. The beginning of the fall of the Ming Dynasty, which had reigned as an absolute hegemonic power in East Asia, was also foreign exchange, including the Japanese Invasion of Korea in 1592.
It is no exaggeration to say that the Korean peninsula was devastated by the war.
There are many legends about Yi Sun-sin, who is revered as a sacred hero, as well as about various righteous army generals throughout the country, and it is still being handed down to this day.
