During the terrible persecutions in Korea (in 1839, 1866, and 1867), 103 Christians were martyred. The martyrs included a few bishops, priests and many lay people. Among them were the first Korean priest Andrew Kim Taegon, and the lay apostle, Paul Chong Hasang. All suffered greatly for the Faith and consecrated the rich beginnings of the Church of Korea with their blood as martyrs. St Pope John Paul II, canonized these martyrs on May 6, 1984.
