What happened
In the wake of the Imjin War and the Manchu invasions, Joseon pursued the strictest policy of isolation of any state in the region, earning the Western nickname the "Hermit Kingdom." Koreans were forbidden to travel abroad except on official diplomatic missions to China or Japan; Chinese merchants could trade at a couple of designated border towns, and Japanese merchants were confined to a single walled compound at Pusan. Korea viewed China as the seat of civilization, though compromised in Joseon eyes by Manchu rule, and viewed Japan as less than fully civilized; contact with Europeans was limited to occasional Jesuit missionaries encountered on diplomatic trips to China, and few Koreans took European visitors seriously as representatives of a great civilization. Meanwhile domestic life remained stable and even flourished: a Sirhak, or Practical Learning, movement of scholars examined science, economics, and society, and figures such as the polymath Tasan and calligrapher Kim Chong-hui produced significant scholarly and artistic work even as the country stayed closed to the wider world.
Why it matters
Korea's deliberate isolation preserved Confucian orthodoxy and internal stability for generations but left the country badly unprepared for the imperial pressure that Western powers, Russia, and a rapidly modernizing Japan would all bring to bear on the peninsula in the second half of the 19th century.
How we know
Joseon's isolation policy is documented directly in the dynasty's own foreign relations records and corroborated by the frustrated accounts of Western and Japanese ships and diplomats who were turned away from Korean ports throughout the 18th and 19th centuries.
