What it is

Joseon's rulers saw Catholicism as a threat because converts refused ancestral rites, the heart of Confucian order. In 1791 Yun Ji-chung was beheaded for burning his late mother's ancestral tablet. Major persecutions followed in 1801, 1839, 1846 and 1866. Andrew Kim Dae-geon (김대건), the first Korean-born priest, was executed in 1846. The 1866 Byeongin persecution alone killed an estimated 8,000 or more, including nine French missionaries. Pope John Paul II canonized 103 martyrs in Seoul in 1984.

Why it matters

The martyrs became central to Korean Catholic identity and gave Korea one of the largest groups of Catholic saints of any country; Pope Francis beatified 124 more in 2014.

Sources and history

Joseon court annals and interrogation records, Hwang Sa-yeong's 1801 'Silk Letter', French missionaries' letters, Bishop Daveluy's collected martyr accounts, and Vatican canonization files.

Questions and debates

Total deaths are uncertain; estimates for all the persecutions together are commonly put at 10,000 or more, and many victims' names were never recorded.

▸Joseon Korea's Confucian state persecuted Korean Catholic martyrsHistorical record

The connection

Joseon's Neo-Confucian order rested on ancestral rites and loyalty to king and family. When Catholics stopped performing those rites, which their church ruled idolatrous, they seemed to attack the state itself. Court factions also used anti-Catholic purges against rivals. The result was waves of arrests and executions from 1791 to 1866.

When and where

Across Joseon Korea, especially around Seoul and in Chungcheong and Jeolla provinces; persecutions of 1791, 1801, 1839, 1846 and 1866, the last under the regent Heungseon Daewongun.

Historical evidence

Joseon royal annals and interrogation records list charges and executions; Catholic accounts and French missionaries' letters describe the same events.

Questions and debates

Historians weigh how much the purges were about faith versus factional politics, as in 1801, when a rival faction targeted Southerner (Namin) officials with Catholic ties.

▸Pope John Paul II canonized 103 of the Korean Catholic martyrsHistorical record

The connection

On May 6, 1984, marking 200 years of Korean Catholicism, John Paul II canonized 103 martyrs at Yeouido Plaza in Seoul before a vast crowd. It was the first canonization held outside Rome in centuries. The saints included Andrew Kim Dae-geon (김대건), Korea's first native-born priest, and lay leader Paul Jeong Ha-sang (정하상).

When and where

Yeouido, Seoul, May 6, 1984; the martyrs died in persecutions of 1839, 1846 and 1866.

Historical evidence

Vatican canonization records and extensive press and film coverage; Pope Francis beatified 124 more Korean martyrs in Seoul in 2014.

Questions and debates

Thousands of other martyrs remain unnamed; the 103 were those whose cases had enough surviving documentation for canonization.
