context_page_description: The Joseon dynasty was a Korean dynastic kingdom that lasted for approximately five centuries. Joseon was founded by Yi Seong-gye in July 1392 and was replaced by the Korean Empire in October 1897. It was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amnok and Tuman through the subjugation of the Jurchens. Joseon was the last dynasty of Korea and its longest-ruling Confucian dynasty.
  During its reign, Joseon encouraged the entrenchment of Chinese Confucian ideals and doctrines in Korean society. Neo-Confucianism was installed as the new dynasty's state ideology. Buddhism was accordingly discouraged and occasionally faced persecutions by the dynasty. Joseon consolidated its effective rule over the territory of current Korea and saw the height of classical Korean culture, trade, literature, and science and technology.
context_section_description: Throughout Korean history, there was frequent piracy on sea and brigandage on land. The only purpose for the Joseon navy was to secure the maritime trade against the wokou. The navy repelled pirates using an advanced form of gunpowder technologies including cannons and fire arrows in form of singijeon deployed by hwacha.
  During the Japanese invasions in the 1590s, Toyotomi Hideyoshi, plotting the conquest of Ming China with Portuguese guns, invaded Korea with his daimyōs and their troops, intending to use Korea as a stepping stone. Factional division in the Joseon court, inability to assess Japanese military capability, and failed attempts at diplomacy led to poor preparation on Joseon's part. The use of European firearms by the Japanese left most of the southern part of the Korean Peninsula occupied within months, with both Hanseong (present-day Seoul) and Pyongyang captured.
  However, the invasion was slowed when Admiral Yi Sun-sin destroyed the Japanese invasion fleet. The guerrilla resistance that eventually formed also helped. Local resistance slowed down the Japanese advance and decisive naval victories by Admiral Yi left control over sea routes in Korean hands, severely hampering Japanese supply lines. Furthermore, Ming China intervened on the side of the Koreans, sending a large force in 1593 which pushed back the Japanese together with the Koreans.
  During the war, Koreans developed powerful firearms and the turtle ships. The Joseon and Ming forces defeated the Japanese at a deep price. Following the war, relations between Korea and Japan were completely suspended until 1609.
