From its establishment on the peninsula in 1784 to Pope Francis’s visit to beatify 124 martyrs, in 2014, 230 years later, the Catholic Church in Korea has experienced massive change as it has sought to navigate persecution, imperialism, national division, war, dictatorship, and democratization. Despite the challenges it has faced, the Korean Catholic Church has managed to transform itself from a tiny, marginalized community into a highly respected part of Korean society with millions of members. This history can be divided into four periods: the time of hope, in which some Koreans came to believe that Catholicism would bring both spiritual salvation and this-worldly knowledge (the early 16th century to 1784); the time of persecution in which Catholics on the Korean peninsula suffered and died for their faith (1784–1886); the time of imperialism (1886–1945), during which Catholics had to balance the demands of nation, state, and faith in the face of increasing Japanese control of their country; and the time of development (1945–2014) as the Catholic Church in South Korea (the Catholic Church in North Korea being essentially destroyed) became an increasingly integral and active part of Korean society.
