On Easter Sunday, April 21, 1946, the year after liberation and the centenary of the martyrdom of St. Andrew Kim Tae-gon, the first Korean priest, Fr. Leo Bang Yu-Ryong, together with his then-students Teresa Yoon Byeong-Hyeon and Marie Teresa Hong Eun-Soon, founded the Congregation of the Sisters of the Blessed Korean Martyrs for which they had been preparing in their parish in Kaesong. It is the "first religious congregation founded by a Korean" in Korea, and it was founded to live the spirit of the Korean martyrs and to fit the Korean mindset.

Soon after the founding of the Congregation, the political situation under the communist regime became severe, and the sisters left their home and their first religious community in Kaesong and moved to Cheongpa-dong, Seoul, in March 1950. On June 25, the Korean War broke out, and in the midst of the difficulties of war and refugee life in the early years of when the Congregation was putting down roots, the sisters continued their religious life without being scattered.

Despite the financial independence of the Congregation being difficult, Fr. Bang Yu-Ryong committed himself to training the sisters in the unique spirituality of the Congregation, “dot nature, silence, face-to-face communion with God and Kenotic Eucharist,” relying on the Gospel words, “Seek first the kingdom (of God) and his righteousness.” (MT 6,33)

As the number of members grew, we sent members for mission around the world beginning with Osaka, Japan, in 1967. In 2007 we established the Daejeon and Suwon Provinces and in 2009 the Region of the Americas (predecessor of the Quasi-Province of the Americas) in order to "start anew in the spirit of the Founder" while "dedicating ourselves to evangelizing the whole world by spiritual maturity through self-emptying and making fraternal communities."

We began as a religious Congregation founded by a Korean for Koreans but were reborn as an "Institute of Pontifical Rite" with the approval of the Holy See on September 20, 2021, the feast of St. Andrew Kim Dae-gon and St. Paul Cheong Ha-sang and their companion martyrs, so that the charism of the Congregation could be a gift to the universal Church.
